WTP Wastewater Treatment

Sewage and Industrial Wastewater Treatment – Understanding the STP/ETP…

What is Wastewater?

Wastewater is a mixture of water and a variety of pollutants, including suspended solids, dissolved organic compounds, nutrients, and microorganisms. Domestic wastewater is typically composed of human waste, food waste, and paper products. Industrial wastewater may include toxic chemicals, heavy metals, oil and grease, and other pollutants.

wastewater

Suspended solids are the largest component of wastewater and can include anything from toilet paper to food scraps. Dissolved organic compounds, such as detergents, food waste, and solvents, can also be found in wastewater. Heavy metals, salts, and nutrients are also present. Nutrients, such as nitrogen and phosphorus, are the primary sources of energy for microorganisms in wastewater. These microorganisms are responsible for breaking down organic matter, which in turn produces carbon dioxide and other gases. This decomposition is essential for the removal of some pollutants, such as ammonia and phosphorus from wastewater.

Health, Environment, and Social concerns associated with wastewater:

  • Health: Wastewater contains bacteria, viruses, and parasites that can cause diseases such as cholera, dysentery, hepatitis A, and typhoid. These diseases can spread through contaminated water. Wastewater also contains toxic chemicals, such as lead, arsenic, and mercury, which can cause serious health problems if ingested. Poorly treated wastewater leads to water pollution on its release, creating an even greater risk to public health.
  • Environment: Wastewater can have a damaging effect on the environment if it is not properly treated or disposed of. Untreated wastewater can pollute drinking water sources and contaminate soil, which can lead to water-borne diseases and the destruction of natural habitats. Wastewater can also cause algal blooms and oxygen depletion in water bodies, which can kill off fish and other aquatic life.
  • Social: Wastewater can have a significant impact on communities. Poorly treated or disposed wastewater can cause an increase in health risks to local residents. If wastewater is not managed properly, it can create an unpleasant living environment due to odor and the presence of vermin. Furthermore, wastewater has an adverse impact on the local economy, as it can contaminate agricultural land and decrease crop yields.

Precautionary measurements are taken to avoid wastewater-related issues

Precautionary measures are taken because untreated wastewater can cause a variety of negative environmental and health impacts.

To prevent these issues, precautionary measures are taken to ensure that wastewater is collected and disposed of properly. The collection of wastewater is usually done through sewer systems, septic tanks, or catchment basins. These systems allow for the safe collection and transport of wastewater to a treatment facility to remove pollutants and contaminants. Then water is released back into the environment.

Disposal of wastewater is also important in avoiding wastewater-related issues. Depending on the type of wastewater and the level of treatment it has undergone, it can be disposed of in various ways. Treated wastewater may be discharged into a local waterway, sprayed onto land, or recycled for use in industrial processes.

Wastewater collection

Wastewater collection systems typically include a network of pipes, manholes, and other structures such as pumping stations, treatment plants, and storage tanks. The collection systems are responsible for transporting wastewater from residences and businesses to a central drainage system. 

Wastewater specific treatment

STP process

STP

A sewage treatment plant is a facility where wastewater is processed to remove pollutants and produce a treated effluent that is safe to return to the environment. Treatment processes may include physical, chemical, and biological processes to remove suspended solids, nutrients, and other pollutants. The treated effluent is typically discharged to a receiving water body such as a river, lake, or ocean.

Primary, Secondary, and Tertiary treatment process in STP:

Primary Treatment

It involves the physical removal of solids from wastewater. This is typically accomplished by screening, grit removal, and primary sedimentation. This is usually done by passing wastewater through large screens or grit channels to remove large debris, such as plastic, sticks, and rags. The wastewater is then pumped through a settling tank, which allows suspended solids to settle to the bottom and the clarified water to flow out of the tank. The settled sludge is usually sent to a secondary treatment process, such as anaerobic digestion or activated sludge. Primary treatment involves the addition of a coagulant and aims at removing grits, coarse solids, oil, and grease if any are present. 

Secondary Treatment

This process uses bacteria and other microorganisms to break down organic matter from wastewater, such as food waste, soaps, and detergents, and convert it into a form to be released into the environment. The process usually involves aeration and clarification, using tanks, basins, and biological filters.

  • Membrane bioreactors (MBRs): Another wastewater treatment option is MBRs. These systems use membranes to separate suspended particles from the wastewater and then allow aerobic or anaerobic bacteria to break down the organic material. The end result is a stabilized effluent that meets environmental standards for safe discharge.
  • Sequential Batch Reactor (SBR): The SBR cycle is composed of several steps: fill, react, settle, decant, and idle. During the reaction stage, the wastewater is aerated and circulated to mix with the microbial population, allowing it to break off the organic matter. In the settling stage, the mixture is settled, allowing lighter biomass and organic matter to rise to the surface and be removed. In the idle phase, the tank is allowed to sit without any aeration or mixing, allowing the biomass to settle and the organisms to rest.
  • Moving Bed Biofilm Reactor (MBBR): MBBR is a type of wastewater treatment system that uses suspended carriers to provide a large surface area for the attached growth of biofilms. The carriers used in MBBRs provide a large surface area for biofilm growth, which helps to reduce the biomass size required for effective treatment.
  • Fluidized Bed Bioreactors (FBBR): FBBR is a type of secondary treatment for the removal of organic pollutants from wastewater. This allows microorganisms, such as bacteria and fungi, to colonize the particles and break down the organic pollutants. It is used in conjunction with primary treatment processes to achieve the highest level of pollutant removal possible.

Tertiary Treatment

The tertiary or chemical treatment process of sewage treatment plants typically involves the addition of chemicals such as calcium oxide, sodium hydroxide, and sodium carbonate to the wastewater. This process helps to break down organic matter and remove suspended solids and other contaminants. The process also helps to balance the pH of the water, reduce odors (Activated charcoal), and reduce the level of disease-causing organisms.

  • Activated charcoal is a carbon filtration that works to remove odor and color by adsorbing and trapping contaminants on the surface of its tiny pores. Activated carbon needs replacement as its capacity to work reduces gradually.
  • Chlorination: The process involves the addition of chlorine or chlorine-based compounds to the water to kill bacteria and other disease-causing microorganisms. The chlorine kills any disease-causing organisms, which helps to reduce the risk of water-borne diseases.
  • Ozonation is a form of the advanced oxidation process that produces extremely reactive oxygen species. Ozone is very reactive and readily oxidizes microorganisms, effectively killing them. Ozone oxidizes the cell wall, membrane, and internal components of microorganisms, damaging their structure and function. Ozone also disrupts the microorganism`s metabolic pathways, leading to cell death.
  • UV treatment – UV water disinfection technique disinfects by penetrating microorganisms and destroying their DNA. Chlorine and other disinfectants can produce toxic disinfection byproducts (THMs or Halo-acetic acids) as well as the dangers that come with their presence on site. Because UV light disinfection is a chemical-free method, it effectively eliminates any concerns about these byproducts.

The important water discharge parameters in STP are biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP), and fecal coliform bacteria.

difference

ETP

An effluent treatment plant (ETP) is a facility used to treat wastewater that is produced by industries and other sources. The treated wastewater (or effluent) is then released into the environment, usually a nearby river, lake, or ocean. ETP reduces the number of pollutants in the wastewater to the levels required by national and local environmental regulations.

In comparison with STP, ETP focuses more on reducing the number of chemical pollutants present in wastewater during its secondary treatment process.

Primary, Secondary, and Tertiary treatment process in ETP:

Primary Treatment

The primary treatment process in ETP typically involves the removal of suspended solids, oils, and other physical contaminants from wastewater. Wastewater is Treated by physical processes such as sedimentation, flocculation, clarification, and filtration.

Secondary Treatment

In secondary treatment, industrial effluent processes are modified as per the content and level of certain chemical pollutants. Following some of the industrial wastewater treatment processes will help to understand this concept better. 

Oil and petroleum industry:

A vast amount of wastewater is generated from the extraction, refining, and transportation of petroleum products. This contains a variety of contaminants, including oil, grease, heavy metals, and other hazardous substances or pollutants. It helps to reduce the concentration of pollutants and contaminants in the effluent to a level that is safe for discharge into the environment. This is achieved through coagulation, flocculation, and biological treatment. The coagulation/flocculation process involves the addition of a coagulant, such as aluminum hydroxide chloride or aluminum sulfate, to the wastewater to remove suspended solids.

The biological treatment process utilizes microorganisms to break down organic material in the wastewater and reduce the concentration of pollutants. Finally, the N:P ratio is an important parameter for the treatment of oily wastewater by using oil-degrading bacteria. By using these techniques, secondary treatment can effectively reduce the contamination level of effluent and make it suitable for discharge into water bodies.

Example: Microorganisms to remove oil contaminants such as Bacteria, Pseudomonas aeruginosa: P. aeruginosa bacteria are able to break down oil and petroleum products due to their ability to produce enzymes that are specific to hydrocarbons. Pseudomonas bacteria are usually introduced into wastewater as slurry. This slurry is made up of a combination of Pseudomonas bacteria, nutrients, and a carbon source. The carbon source is important because it provides the bacteria with the energy they need to break down the oil and petroleum-based pollutants.

Other common microorganisms used in the oil and petroleum industry for wastewater treatment include bacteria such as Acinetobacter, and Bacillus, and fungi such as Aspergillus and Trichoderma.

Textile industry (Dyes and paints, colorants,):

The main purpose of secondary treatment is to provide BOD removal beyond what is achievable by simple sedimentation. It also removes appreciable amounts of oil and phenol. The dissolved and colloidal organic compounds and color present in wastewater are removed or reduced to stabilize the organic matter. Textile processing effluents are amenable to biological treatments.

Textile waste also contains significant quantities of non-biodegradable chemical polymers. For non-biodegradable pollutants, filtration technologies are utilized in the textile industry to clean wastewater. Traditional membrane processes in textile wastewater treatment include the use of ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes. The selection of membrane technologies for textile effluent relies on costs based on the balance between water flux and solute retention. RO also becomes less effective when osmotic pressure, is caused by high salt concentration in the feed wastewater. Becomes too high to obtain a reasonable transmembrane permeate flux without applying excess transmembrane hydraulic pressure.

The membrane filtration system typically consists of a series of membranes with differing pore sizes and compositions that are used to remove particles from the wastewater. The membranes are typically made from polymeric materials such as polyvinylidene fluoride (PVDF), polysulfone, or polypropylene.

Metallurgic, chemical, and Fertilizer industry:

This is usually done through the application of an activated sludge process, trickling filter, rotating biological contactors, and oxidation ponds. The activated sludge process is used to remove organic pollutants from wastewater by using a variety of microorganisms. Trickling filters use a bed of media on which microorganisms grow to degrade the organic pollutants. Rotating biological contactors use a series of rotating plastic disks on which microorganisms grow and degrade organic pollutants. Finally, oxidation ponds are used to provide long-term biological treatment.

Tertiary Treatment

The tertiary treatment or biological treatment process in an ETP is designed to remove organic and inorganic pollutants from wastewater. This process is typically used in applications where the effluent needs to be treated to a high level of purity. The water is then treated with chlorine, ultraviolet light, or ozone to kill any remaining bacteria, viruses, and other pathogens before it is released into the environment. Primary and secondary treatment typically gets wastewater only clean enough to discharge safely into the environment. Tertiary treatment can achieve levels of water purification that make the water safe for reuse in water-intensive processes or even as drinking water.

Tertiary wastewater treatment often works by using a combination of physical and chemical processes to remove harmful microbiological contaminants. The process usually involves filtration followed by additional disinfecting treatment. In some cases, tertiary treatment may also use other specialized treatments like lagoon storage, biological nutrient removal, and nitrogen and phosphorus removal.

Final water disposal activities:

All water either from STP or ETP is finally safely disposed into the environment or reused depending upon the quality of wastewater as follows.

  • Filters: Tertiary filtration components can contain a few different materials. Sand and activated carbon filters are common, and filters can also contain fine woven cloth. The filters come in a few types, including bag filters, drum filters, and disc filters. Backwash cleans the media components to ensure their continual functioning.
  • Disinfecting: The process of tertiary disinfection may take a few different forms. Chlorine is one of the most commonly used disinfectants in wastewater treatment. Ultraviolet light is a common disinfectant in tertiary treatment. Ozone is highly reactive and can destroy most microorganisms it comes into contact with.
  • Discharge: Once the wastewater has undergone tertiary treatment, it is ready for discharge back into the environment. Many municipalities have specific requirements for the discharge of treated water. Tertiary treatment should be sufficient to meet those standards, keep the environment clean and preserve human health, experts say.
  • Reuse: Many treatment plants use tertiary treatment specifically to make the water safe for human ingestion. Water that has received tertiary treatment is also suitable for numerous operations that require clean water. These include industrial and manufacturing processes, oil and gas extraction and refining, utilities cooling, and agricultural practices like irrigation.
Wastewater Treatment

Wastewater Management and Its Important Components

The drainage systems and wastewater collection are important components of proper collection and disposal of the city’s infrastructure. They are responsible for maintaining a safe and healthy environment by preventing the spread of diseases and pollutants. The drainage systems and wastewater collection are most often divided into two main components. The collection system includes sewers and pipes, and the treatment system, which includes wastewater treatment plants. The drainage system collects rainwater runoff and sewage from homes, businesses, and other sources. Then transports the collected wastewater to a treatment plant, where it is treated, cleaned, and released back into the environment.

Drainage System:

The drainage system is a network of pipes, drains and other structures used to collect and remove surplus water and waste from buildings, roads, and other areas. It is an integral part of modern life, allowing for the removal of rainwater, sewage, and other waste materials.

drainage

The drainage system is typically composed of two components. A surface drainage system collects and disposes of rainwater and surface runoff. A subsurface drainage system collects and removes waste water from buildings.

Surface drainage systems are designed to collect and convey excess water away from roads, buildings, and other areas. They usually consist of a series of underground pipes and channels that collect runoff from rooftops, driveways, and other surfaces. The collected water is then directed to a storm sewer, which carries it away from the area. In some cases, the water is directed to a nearby water body or a natural wetland.

Subsurface drainage systems are designed to collect and remove wastewater from buildings. These systems are typically comprised of a series of pipes and drains that collect wastewater from plumbing fixtures, such as toilets and sinks. It is then directed to a septic tank or a public sewer system, where it is treated before being discharged into a nearby water body.

Wastewater Collection:

Wastewater collection systems typically include a network of pipes, manholes, and other structures such as pumping stations, treatment plants, and storage tanks. The pipes are usually constructed from PVC, concrete, or iron and they come in a variety of sizes and shapes to accommodate different types of wastewater. The manholes are used to allow access to the pipes for cleaning and maintenance, and they are usually equipped with safety equipment such as gas detectors and airflow monitors.

Wastewater collection systems are responsible for transporting wastewater from residences and businesses to a central drainage system. In most cases, wastewater is collected through a network of underground pipes that lead to a sewage treatment facility. The drainage system works in conjunction with the wastewater collection system by receiving wastewater from the collection system and then distributing it to the treatment facility. The drainage system removes excess water from the surrounding area and provides a safe and efficient disposal of wastewater.

Wastewater Collection Categories:

Wastewater collection systems can be divided into two categories: sanitary sewers and combined sewers. Sanitary sewers are wastewater systems that collect it from homes and businesses and transport it to a wastewater treatment plant, while combined sewers collect both stormwater and wastewater and transport them to a wastewater treatment plant. The drainage flow rate is the amount of water that is discharged from a drainage system over a given period of time. This rate is usually expressed in cubic feet per second (CFS). The drainage flow rate can be affected by factors such as the size of the drainage system, the slope of the terrain, the amount of rainfall or snowmelt, and any obstructions in the flow.

The volume of water collected in wastewater treatment plants (WTPs) is determined by the size of the plant and its capacity. Normally, the size and type of treatment process used will determine the volume of water that can be processed in a given period of time. The capacity of WTPs can range from 1.9 million liters per day to over 80 million liters per day. Water collected by WTPs depends on the amount of wastewater generated by the community and precipitation in the area.

Treatment and Discharge:

Pumping stations are used to move wastewater from low-lying areas to higher points where it can be more easily transported. Treatment plants used to clean and treat wastewater involves a combination of physical, chemical, and biological processes.

Physical processes involve the removal of large suspended solids, such as sand, gravel, and other debris. This is usually done through sedimentation, filtration, or centrifugation. Chemical processes involve the addition of chemicals, such as chlorine or alum, to break down organic matter and other pollutants. Biological processes involve the use of microorganisms, such as bacteria, to break down organic matter in wastewater.

The treated wastewater is then discharged into a receiving water body, such as a river, lake, or ocean.

Tabulation of general wastewater parameters

parameters

By tabulating general wastewater parameters, Population Control Board is able to understand the impact of wastewater on the environment. This information can then be used to develop measures to reduce the negative impacts of wastewater on the environment.

Wastewater management systems must be designed and operated to ensure that they adequately collect, and treat the wastewater and prevent environmental contamination.

Wastewater management systems should also be designed to prevent flooding and maintain an acceptable level of water quality. This may include the installation of pumps, detention basins, and other structures to reduce the effects of flooding. It may also include the use of stormwater management systems to prevent soil erosion and runoff of polluted wastewater.

In nature, wastewater treatment occurs in natural ponds, wetlands covered with mangroves, and heavy plantation and water lagoons.

Similarly, when these natural phenomena are applied for wastewater treatment by artificial means, both natural, as well as artificial resources are utilized. At the beginning of the process, wastewater is allowed to stabilize and remove suspended solids particles by aggregation, flocculation, and sedimentation in waste stabilization ponds. Then the water slowly flows to artificial wetlands where the plantation of diverse phytoremediation plants sequesters many pollutants and clears water to the maximum extent by phytoremediation process. Furthermore, in natural processes, the wastewater from wetlands enters the natural water bodies and water streams. 

wastewater

Constructed wetlands:

Constructed wetlands are artificial wetlands that are specifically designed to treat wastewater. They consist of a shallow body of water with a bed of gravel or sand and vegetation planted in them. As wastewater is pumped into the wetland, it flows slowly through the gravel or sand and is filtered by the plants, soil, and microorganisms. The microorganisms break down organic matter and suspended solids, while the plants and soil filter out pollutants and heavy metals.

Water Lagoons:

Lagoons are made up of a series of interconnected ponds, which are designed to capture, store, and treat wastewater. Each lagoon is filled with wastewater that is circulated and aerated, allowing beneficial bacteria and enzymes to break down harmful contaminants. This process helps to reduce the amount of organic matter, toxins, and other pollutants in the water, making it safe for reuse or discharge. As the water moves through the lagoons, suspended solids settle to the bottom, providing a nutrient-rich environment for beneficial bacteria and other organisms to thrive. The bacteria and other organisms help to further break down the contaminants and create a clean, safe effluent.

Importance of Wastewater management

  • Conservation of Resources: It helps to conserve valuable resources, such as energy and water, by recycling.
  • Preservation of Human Health: Wastewater management reduces the risk of water-borne diseases and helps in preserving public health.
  • Reduced Pollution: It helps to reduce the pollutant level in water sources and helps to protect aquatic ecosystems and wildlife.
  • Improved Water Quality: Water quality in rivers and lakes can be improved and making them safer for human use.
  • Reduced Contamination: It helps to reduce contamination of drinking water sources and ensure that they are safe for human consumption.
  • Economic Benefits: Proper wastewater management can help to reduce the costs of water treatment and disposal, providing economic benefits.

Conclusion:

Wastewater management is a complex process to manage. The infrastructure of a drainage system in wastewater management is a basic requirement. Improper drainage and wastewater management lead to wastewater-related issues in society that affects the quality of life. Poorly designed drainage systems can lead to poor sanitation, water pollution, and various serious water-related health hazards. Impotent drainage system flooding during rainy seasons may occur due to water logging which causes life and economic losses. Proper management is essential to avoid above mentioned damages. By investing in an efficient infrastructure and technology, wastewater can be well managed and we can enjoy a hygienic life.

Innovation in waste management techniques is a continuous process due to emerging novel waste categories.  Recently, the development of new technologies, such as 3D printing has been used to create new items from waste materials. This helps to reduce the amount of waste going to landfills and encourages manufacturers to use recycled materials in their production processes.

Overall, innovation in waste management is helping to reduce the environmental impact of waste and make the world a cleaner and healthier place.

Ways of Waste Management:

1. Reduce: Reducing the amount of waste produced is the first step in waste management.   This involves making changes to the way people consume products, such as buying items with less packaging, using reusable items instead of disposable ones, and buying in bulk.

2. Reuse: Reusing items is a great way to reduce waste. Items that can be reused include plastic bags, water bottles, and food containers.

3. Recycling: Recycling is a process of collecting and sorting materials, such as paper, plastic, and metal, to be reused. Recycling helps reduce the amount of waste that needs to be disposed of and can also help conserve natural resources.

4. Waste Collection and Transportation: Waste collection and transportation is the process of collecting and transporting waste to designated areas where it can be properly disposed of. This process helps keep communities clean and free of waste.

These ways of waste management are to reduce the amount of waste produced and to ensure that waste is managed safely and responsibly. This also includes the prevention of pollution and the protection of human health and the environment. Waste management also helps to ensure that waste is disposed of in an environmentally sound manner, while also helping to reduce the costs associated with waste disposal.

The basis of these waste management concepts following some innovative, & futuristic solutions is being explored. Apart from this, already-known environmental solutions are implemented for the management of biodegradable waste and some of the potential biological solutions are discussed in this context.

A. Innovative Solutions:

Waste-to-Energy Technology:

energyfromwaste

Waste-to-energy (WTE) technology is a process of converting non-recyclable waste into usable energy. This process is often done by burning the waste in an incinerator. The resulting energy can then be used to generate electricity and heat.

Waste-to-energy technology is a popular solution for municipal solid waste, but can also be applied to agricultural and industrial waste.

Bioenergy from methane and biogas is produced from the anaerobic digestion of biodegradable waste. Anaerobic digestion is a process by which organic matter is broken down by bacteria in the absence of oxygen. During this process, biogas is produced. Biogas can be used directly as fuel in domestic applications or processed further to produce heat and electricity on a commercial scale. The benefits of using biogas and methane from the anaerobic digestion of biodegradable waste include the reduction of landfill waste, the reduction of greenhouse gas emissions, and the production of renewable energy. Additionally, the process of anaerobic digestion can be used to produce other valuable products, such as nutrient-rich compost, which can be used to improve the fertility of agricultural land.

Smart Waste Bins:

Smart waste bins are an innovative tool in waste management that is designed to make waste collection and disposal more efficient and cost-effective. It uses sensors, wireless networks, and software to monitor and manage waste levels in real time. The data collected can be used to improve waste collection routes, identify problem areas, and help identify potential areas for improvement in the waste disposal process.

Smart bins can help reduce the amount of waste sent to landfills by alerting waste collectors when the bin is full and needs to be emptied. This can help to reduce the amount of waste that goes to landfills and provide a more efficient and cost-effective waste disposal system.

This also helps to reduce carbon emissions into the atmosphere by changing the fate of waste. Additionally, smart waste bins can be used to collect recyclable materials, making it easier for them to be sorted and recycled.

Overall, smart waste bins are an innovative tool in waste management that can help reduce the amount of waste sent to landfills, provide data to waste management companies and local governments to develop better waste management policies and strategies and help to reduce the environmental impact of waste.

Plasma Gasification:

Plasma Gasification is a cutting-edge innovation in waste management that uses high temperatures and electrical energy to convert organic waste into a gaseous fuel. This gaseous fuel can then be used for energy production, making it an efficient and sustainable way of managing the world’s waste.

Plasma Gasification works by vaporizing organic waste into its base elements. These elements are then converted into syngas, a mixture of hydrogen and carbon monoxide. The syngas can then be used to generate electricity, produce synthetic fuels, and create other useful materials. In addition, the process produces a solid residue, which can be used as an alternative fuel source or recycled back into the environment.

Plasma Gasification is an extremely efficient way to manage waste. This is because it has the ability to convert almost any kind of organic waste into a usable form of energy. This makes it a much more efficient way of managing organic waste than traditional methods such as burning or landfilling. In addition, the process produces far fewer emissions than burning organic waste, making it a much more environmentally friendly option.

Plasma Gasification is already being used in some parts of the world and is expected to become more common as the technology continues to develop. This is a great innovation that provides a sustainable and efficient way of managing waste, and it is likely to become a major part of the global waste management landscape in the future.

Pneumatic Waste Collection:

pneumaticsystem

Pneumatic waste collection is an innovative and efficient way to manage waste. It is an automated system that uses a network of pipes to transport waste from one location to another, providing a more efficient, cost-effective, and environmentally friendly solution. This system is used in both commercial and residential buildings and is becoming increasingly popular due to its many advantages.

The main advantage of pneumatic waste collection is its convenience. Waste products are collected in containers which are then loaded onto a conveyor belt or other conveyance system. This belt or other conveyance system then transports the waste to a centralized collection point. From there, it is sorted before being transported to a waste-processing facility. This automated process eliminates the need for manual labour and reduces the risks associated with manual waste collection. It also reduces the amount of time and resources needed for waste collection, which in turn reduces costs for businesses and households.

Another advantage of pneumatic waste collection is its environmental benefits. By eliminating manual labour, it reduces the number of resources used in waste management, such as fuel and energy. It also reduces the amount of pollution from emissions from vehicles used for waste collection. Additionally, it allows for better waste segregation, meaning that recyclable materials are more easily separated from non-recyclable materials. This results in less waste going to landfills, resulting in a more eco-friendly waste management solution.

Overall, pneumatic waste collection is a highly efficient and cost-effective solution for waste management. It eliminates the need for manual labour, reduces environmental impacts and provides a more organized and efficient way to manage waste. It is an innovation that is quickly gaining popularity and is likely to become even more important in the future.

Fleet Management System:

Fleet management systems are playing an increasingly important role in the innovation of waste management. By providing real-time access to data about fleet vehicles, fleet management systems allow for more efficient operation of waste collection and disposal services. This data can be used to monitor and optimize routes, predict maintenance needs, and ensure fuel efficiency.

Advanced analytics capabilities have enabled fleet managers to gain insights into the performance of their fleets, helping them identify areas for improvement and cost savings. They can also use these insights to develop new strategies for managing waste disposal, such as reducing the number of vehicles used for collection or introducing more efficient collection methods.

Fleet management systems also allow for remote monitoring of waste collection and disposal services, allowing managers to track and monitor waste collection and disposal activities in real time. This data can be used to quickly identify problems and take corrective action.

Overall, fleet management systems are playing a key role in the innovation of waste management. By providing access to real-time data and advanced analytics capabilities, fleet managers are able to optimize waste collection and disposal operations, improve safety, and reduce costs.           

AI Waste Sorting:

Al waste sorting innovation is a revolutionary new approach to waste management that has been developed by the Al-Waste Group. The group is dedicated to finding ways to reduce the amount of waste that is sent to landfills, incinerators, and other disposal methods. Al-Waste’s sorting innovation is based on a combination of mechanical and optical sorting methods, which can separate and sort items of waste into different categories.

The sorting process begins by using a machine that sorts the waste into categories such as plastic, paper, glass, and metal. The machine then uses a series of optical scanners to identify and separate the different materials. This process is repeated several times to remove items that are too small to be sorted, and then the sorted items are further separated by weight and size. Finally, the materials are further sorted into various waste streams such as compost, recyclable, and hazardous materials.

Al-Waste’s sorting innovation is a great example of how innovative thinking can lead to more sustainable waste management solutions. By using the latest technologies and techniques, Al-Waste is helping to reduce the amount of waste sent to landfills, while also increasing the number of materials that can be recycled and reused. This is a great way to reduce the environmental impact of waste management while also helping to create a more sustainable future.

Bioremediation of waste dumping site to remove pollutants (Toxic and Heavy metals) by biomining and bioleaching

Bioremediation of waste dumping sites is a process used to reduce pollutants from contaminated areas and to restore them to a safe and usable condition. Biomining and bioleaching are technologies used in the bioremediation of waste dumping sites to remove heavy metals, such as lead, arsenic, and mercury, from these areas.

Biomining is a process that uses microorganisms (bacteria) to extract minerals of heavy metals from ore deposits. In this process, microbial cells (Prokaryotes and fungi) are used to break down the minerals, and also form complexes with metal ions by secreting chelating substances to chelate them. These metal microorganism complexes are then extracted from the ore through a process of leaching. This technology is used to extract heavy metals from waste dumping sites, which are then reused as resources.

Bioleaching is another bioremediation process that uses certain species of microorganisms to oxidize heavy metals. Microorganisms are then released and collected in a solution leading to the removal of the pollutant from the contaminated site.  This solution can then be treated to remove the heavy metals for recycling purposes or safe disposal.

These two technologies are effective in removing heavy metals from waste dumping sites and restoring them to a safe and usable condition. They are also relatively inexpensive, making them an attractive option for waste management and restoring polluted land.

B. Other Modern Technologies:

One of the most innovative novel technologies in waste management is the use of intelligent monitoring technology. This technology is used to detect, track, and analyse the sources of waste and how it is being managed. It utilizes smart sensors and artificial intelligence algorithms to detect and track the sources of waste, analyse its composition, and identify the best methods for managing it. This technology can be used to help cities and businesses better manage their waste.

robot

Another novel technology in waste management is the use of robotic waste collectors. These robots are equipped with sensors and cameras to detect and collect waste from areas that are hard to reach. They utilize GPS technology to accurately track and collect waste and can be programmed to perform tasks autonomously. This technology has the potential to reduce the amount of human labour needed for waste collection, thereby improving the efficiency and cost-effectiveness of waste management operations.

Finally, there is the use of cloud-based waste management technology. This technology allows businesses and cities to efficiently manage their waste using a cloud-based platform. It enables them to track and monitor waste streams, set up alerts for when waste needs to be collected, and use predictive analytics to forecast future waste needs. This technology can help businesses and cities reduce their waste generation and save money.

C. Technological interventions in Biological and biochemical Solutions:

Localized Composting Models:  

For domestic organic waste management, modern tools are developed to offer a localized solution. This helps to convert and reduce organic waste produced in houses and small businesses. Composting is a process of breaking down organic kitchen waste, food, vegetables left over, and yard waste, into nutrient-rich soil. Composting can reduce the amount of waste that needs to be disposed of as well as provide fertilizer for plants. Furthermore, to improve compost quality, techniques like vermicomposting are also followed.

Anaerobic Digestion (AD) of Environment Polluting Biowaste:

Biowaste containing pathogenic bacteria if dumped openly in the environment can pollute waterbodies and spreads diseases. To avoid this proper disposal of biological waste is very much essential. Anaerobic digestion is a process of breaking down organic waste in the absence of oxygen. This process produces biogas, which can be used to generate electricity and heat. Faecal waste, farm animal excreta, and water treatment plant (STP/ETP) sludge are anaerobically digested to produce energy and nutrient-rich manure. Government authorities help rural communities to implement basic anaerobic digestion technologies by providing funds and subsidising the construction cost. This is to promote the application of available technology for hazardous waste management and also to promote rural development.

 Agricultural waste for bioenergy generation: 

Bioenergy generation technology is a viable option for the conversion of agricultural waste into energy. Second-generation (2G) biofuels majorly focused on the production of ethanol as a liquid fuel from agricultural residues. The acid, alkali or enzyme-based digestion of cellulosic agricultural residue is performed to produce fermentable sugar from complex lignocellulosic biomass. In the subsequent fermentation step, the produced sugar broth is utilized for the production of ethanol as a transportation fuel. This innovative solution will reduce the great issue related to agricultural waste otherwise which is burned in the fields promoting more pollution.

As explained earlier anaerobic digestion is also performed with various types of easily digestible agricultural waste to produce methane-rich biogas. This biogas can be used to generate electricity or heat, as well as used as a transportation fuel.

Liquid Waste:

Scrubbing of Environmental Pollutants from the Industrial Effluent and Stack Gases:

These processes use a combination of filtration and scrubbing technology to reduce harmful gases and liquids from stack and effluents respectively. Pollutants are collected from the exhaust by passing it through a filter material, such as an activated carbon filter, which captures the pollutant particles. The captured pollutants are then removed from the filter material through a scrubbing process, which involves the use of a liquid or gas scrubbing solution.

The scrubbing solution is typically a combination of water and a chemical that reacts with the pollutants to neutralize them. Activated carbon filters are also used to reduce the emissions of volatile organic compounds (VOCs). The captured pollutants are then further processed in a reaction tank where they are converted into harmless compounds.    

In biological methods, microorganisms are used to sequester poisonous gases and Heavy metal ions from air and water respectively. These organisms utilize a variety of chemicals as their nutrients and can be embedded into filter material for treatment. These bacteria embedded into filter material start utilizing pollutants after placing the filters in liquid waste. The filter material acts as a substrate, providing microbes with the necessary nutrients and environment to grow and thrive.

Use of Enzymes in Wastewater Treatment:

Enzymes are biological molecules that catalyse chemical reactions in living organisms. They are essential in all biochemical pathways and are used in a variety of industrial processes. They can be produced from a variety of microorganisms through industrial fermentation processes. In wastewater treatment, enzymes break down organic waste into smaller molecules that are easily removed in further treatment. Enzymes also remove oil and grease, as well as inorganic compounds such as heavy metals.

Ex. Proteases: Proteases break down proteins in sewage sludge to make it easier to handle and dispose of. Lipase breaks down lipids and fats in wastewater, which can reduce odours and help to improve water quality.

Phyto, Phyco, and Microbial Remediation:

Phytoremediation is the use of plants to remove pollutants from contaminated water. This process involves growing plants that are able to absorb pollutants from the water and contain them within their tissues.

Phycoremediation is the use of algae to remove pollutants from contaminated water. Algae can absorb and contain pollutants like heavy metals, organic compounds, and nutrients.

Microbial remediation is the use of microorganisms to degrade pollutants contained in water. Microorganisms can break down pollutants such as oil, pesticides, and solvents, making them less harmful and easier to manage.

These methods of liquid waste management are all effective in reducing the number of pollutants that enter the environment.

Green House Gases (GHGs) – CO2 sequestration using Phycoremediation and Phytoremediation:

co2sequestration

The most abundant GHGs Carbon dioxide (CO2), is one of the most significant contributors to global warming. It has become crucial to find ways to reduce emissions and sequester the CO2 already present in the atmosphere. Direct Air Capture (DAC) by physical and chemical means to concentrate and store CO2 is one option. Where, captured CO2 can be stored in gaseous, liquid or solid form under the earth’s crust, and many other places.

Amongst the all-potential CO2 sequestration technologies environmental solutions are more economic and promising (for example Phycoremediation and Phytoremediation). These methods involve the use of plants, microorganisms, and algae to capture CO2 from the atmosphere. In the end, this absorbed CO2 is stored in the form of biomass. This biomass can then be used to produce biofuels and a variety of biocommodity products.

Conclusion and Future Prospects:

A variety of solutions are available for waste management and many innovation options are added with novel research every year. But the major constraints related to technology implementation always remain unresolved. In many cases, waste managing authorities fail to estimate the scale at which waste is generated. They also fail to determine the technology required to manage the waste.

Novel technological interventions are quite promising to resolve waste generation and its management issues. In the future improvement in waste management can be seen if timely adaptation and implementation of novel solutions are made. Furthermore, the exploration and execution of more environmental solutions in the waste management sector would lead to sustainable developments.

Waste and Its Management

What is Waste?

Waste is any material that is discarded or left unused after its initial purpose has been served. It is a major problem in the world today, with large amounts of waste created by human activities. Waste can be found in many forms, including solid, liquid, and gaseous. It can be hazardous or non-hazardous and can come from a variety of sources, such as industrial processes, agriculture, and domestic activities. The improper disposal of waste can have serious environmental and health consequences. Solid waste can contaminate groundwater and soil, while liquid waste can pollute rivers and other bodies of water. In addition, some forms of waste can release toxic substances into the atmosphere, causing air pollution. Waste can also lead to the spread of disease, as some types of waste can be a breeding ground for bacteria and viruses.

The most effective way to address the issue of waste is to reduce, reuse, and recycle. Reducing waste means using less of the resources available and cutting down on the amount of waste produced. Reusing materials instead of buying new products can help reduce the amount of waste produced. Finally, recycling waste can help to reduce the amount of waste that needs to be disposed of, as materials can be processed and reused. Waste is an ever-growing problem that needs to be addressed urgently. By reducing, reusing, and recycling, we can all do our part to help reduce the amount of waste produced.

Classification of Waste

Classification Depending upon the Waste Types:

Solid Waste:

Solid waste is any type of waste material that is discarded after use and cannot be reused or recycled. This type of waste is usually composed of common items such as food scraps, packaging materials, paper and cardboard, and other items that are no longer needed. Solid waste is the most common form of waste and accounts for over two-thirds of all waste produced. Solid waste is a major threat to the environment, as it can contaminate soil and water, pollute the air, and create health risks.

Liquid Waste:

Liquid waste refers to waste materials in liquid forms, such as wastewater, sewage, and industrial effluents. this type of waste can come from a variety of sources, including homes, businesses, and industries. It is generally composed of a mixture of organic and inorganic substances, including oils, grease, detergents, suspended solids, and other contaminants. Liquid waste is considered hazardous when it contains any type of pollutant that can be harmful to humans, animals, and the environment.

Classification Depending upon the Source:

  • Industrial waste is generated by commercial and industrial processes, such as manufacturing, mining, and energy production.

  • Municipal waste is generated by households and businesses, including packaging, food waste, and other household items.

  • Construction and demolition waste is generated from the construction and demolition of buildings and other structures.

  • Agricultural waste is generated during agricultural practices of growing, harvesting, and recovering food grains. This waste is mostly organic and manageable at the source of its production in many conventional ways. 

Depending upon its Management:

  • Recyclable waste is any material that can be reused or repurposed for another purpose.

  • Compostable waste is any material that can be broken down into organic matter and used as fertilizer or soil conditioner.

  • Landfill waste is any material that cannot be recycled or composted and must be disposed of in a landfill.

Classification by the Categories:

Furthermore, all types of waste can be divided into two main categories: hazardous and non-hazardous.

  1. Hazardous waste is any material that is toxic, flammable, corrosive, radioactive, or otherwise dangerous to human health or the environment. Examples of hazardous waste include industrial chemicals, medical waste, electronic waste, etc.

  2. Non-hazardous waste is any material that is not hazardous and poses no risk to human health or the environment. Examples of non-hazardous waste include paper and cardboard, food waste, yard waste, etc.

Waste Management

The most common methods of solid waste management include recycling, composting, incineration, and landfilling. Each of these methods has its own benefits and drawbacks. Recycling involves reprocessing and reusing discarded materials while composting is the process of breaking down organic materials into a soil-like material. Incineration is a method of burning waste materials to reduce their volume while landfilling involves burying the materials in a designated area.

solidwastemanagememt

In addition to these methods, there are several other strategies for managing solid waste. These include source reduction, reuse, and energy recovery. Source reduction involves reducing the amount of waste produced in the first place, while reuse involves finding new uses for existing materials. Energy recovery involves burning waste to create energy. Regardless of the strategy used, it is important to ensure proper solid waste management. This includes establishing regulations and policies that promote proper waste management, as well as educating the public on the importance of waste reduction and recycling. Proper waste management can help to reduce air and water pollution, conserve resources, and reduce the amount of landfill waste. Additionally, proper disposal of solid waste is essential to ensure that it does not end up in landfills or waterways.

Liquid Waste Management:

The management of liquid waste is important in order to protect public health and the environment. Liquid waste must be properly collected, treated, and disposed of in order to reduce potential risks to human health and the environment. Treatment options vary depending on the type and composition of the liquid waste. Common methods of treatment include physical, chemical, and biological processes. The disposal of liquid waste is regulated by local and state laws, which specify the types of waste that must be disposed of in a certain manner and the methods that must be used to do so. In most cases, liquid waste must be disposed of in accordance with federal and state regulations and must be managed in a manner that does not pollute the environment or pose a threat to public health.

Impact of hazardous waste:

The most immediate effect of hazardous waste is the contamination of land, air, and water. Hazardous waste can contain a variety of harmful chemicals that can be released into the environment and can cause a wide range of health problems. Long-term exposure to hazardous waste can lead to cancer, birth defects, and other serious health problems. Hazardous waste can also contaminate nearby groundwater and surface water, creating a risk of contamination for drinking water sources. This can lead to a host of health problems, such as poisoning, gastrointestinal and respiratory illnesses, and even death.

The presence of hazardous waste can also impact the local ecology. It can contaminate soil, killing off beneficial organisms and disrupting the natural balance of the ecosystem. Hazardous waste can leach into rivers and streams, killing off fish and other aquatic life. Additionally, improper handling of hazardous waste can lead to accidental spills, which can have a devastating effect on the environment. Spills can contaminate the soil, water, and air, leading to long-term damage. Overall, hazardous waste can have a devastating effect on human health and the environment. It is important to take steps to ensure that hazardous waste is properly managed and disposed of in order to minimize its potential impacts.

How to Manage Hazardous waste:

hazardouswaste

  • Identify Hazards: Identify the type of hazardous waste you are dealing with and its associated risks. This information should be documented and kept on file.

  • Contain and Label: Contain the hazardous waste in a secure area and use appropriate labels. The labels should specify the type of waste, the quantity, and any safety precautions.

  • Develop a Management Plan: Develop a plan for the safe storage, transport, and disposal of hazardous waste. Make sure the plan is in compliance with any applicable regulations.

  • Monitor and Document: Monitor the hazardous waste to ensure it is stored safely and that it is not released into the environment. Document any changes in the hazardous waste and its storage.

  • Train Employees: Train all employees on the safe handling and disposal of hazardous waste. Make sure they are aware of any safety precautions and regulations.

  • Dispose of Properly: Dispose of hazardous waste in a way that is safe and compliant with all regulations. This could include recycling, incineration, or other means.

  • Audit and Review: Perform regular audits and reviews to ensure the hazardous waste is being managed properly. Document any changes or improvements that need to be implemented.

Impact of Non-Hazardous Waste:

Non-hazardous waste, such as plastics, can have a devastating effect on the environment. Plastic consumption has skyrocketed over the past few decades and continues to be a major contributor to pollution. One of the main ways that non-hazardous waste is bad for the environment is through the release of toxins and chemicals. When plastic is not disposed of properly, it can leach toxins into the environment. This can cause soil contamination, air pollution, and water contamination, leading to serious health and environmental issues. Non-hazardous waste can also be bad for the environment when it is not properly recycled or disposed of. When plastic waste is not recycled, it often ends up in landfills or in the ocean, where it can take hundreds of years to decompose. This can cause serious damage to the surrounding environment, leading to water and air pollution, as well as the release of dangerous toxins.

Non-hazardous waste also contributes to global warming. As plastic breaks down, it releases greenhouse gases, which can contribute to the warming of the planet. It can also cause significant damage to local wildlife, as animals can become trapped in the plastic or ingest it, leading to serious health issues. Overall, non-hazardous waste can lead to serious environmental damage if it is not disposed of properly. It can cause air and water pollution, contribute to global warming, and lead to serious health issues for animals and humans alike. To help protect the environment, it is important to make sure that non-hazardous waste is properly recycled or disposed of.

How to manage Non- hazardous Waste:

resuserecycle

  • Reuse: Reuse of non-hazardous waste should be encouraged whenever possible. Items such as paper, cardboard, plastic, aluminum, glass, and other materials can be recycled or reused in new products.

  • Reduce: Minimizing the amount of non-hazardous waste generated is one of the best strategies for managing it. This can be done by reducing the number of products purchased, reusing items, and avoiding single-use items.

  • Recycle: Recycling non-hazardous waste is one of the best ways to manage it. Recycling not only helps reduce waste but also conserves resources and energy.

  • Compost: Composting non-hazardous waste helps create a nutrient-rich soil amendment that can be used in gardens and landscaping.

  • Donate: Donating non-hazardous waste to organizations such as Goodwill and the Salvation Army can help reduce waste and provide a valuable service to the community.

  • Dispose of: When non-hazardous waste cannot be recycled or reused, it should be disposed of properly. This can include taking it to a landfill or hazardous waste facility.

Future of waste management:

With technological advancements in waste collection, sorting, and disposal, all the processes can be managed with advanced instruments and robotics. Some of the futuristic solutions for waste management are smart waste bins, plasma gasification, pneumatic waste collection, fleet management systems, al waste sorting. These all options can help to make waste management sustainable and environmentally friendly but, the infrastructure required to produce and implement these technologies need to be developed.

Chlorophyll Rich Diet for Good health – Reality or…

There is a piece of scientific evidence to support the claim that chlorophyll improves hemoglobin. Chlorophyll has a very similar structure to hemoglobin, which is an essential functional part of red blood cells that carries oxygen. Because of this similarity, chlorophyll is thought to contribute to hemoglobin production and increases RBC count in the blood. There are many different ways to get chlorophyll into the body, i.e. through nutritional supplements, vegetable juice, and eating green leafy vegetables.

The research behind chlorophyll improving hemoglobin dates back to the 1930s. Dr. Ann Wigmore, from Boston, was one of the first to suggest that chlorophyll could help improve hemoglobin levels. She noticed that people who ate a lot of dark green leafy vegetables had higher hemoglobin levels. Some laboratory experiments and animal trials also suggest the same. Many other researchers all over the world are trying to find out exactly what triggers hemoglobin production on the consumption of a chlorophyll-rich diet.

Chlorophyll

Chlorophyll is a green pigment found in plants that is essential to the process of photosynthesis. It absorbs light from the sun and uses it to convert carbon dioxide and water into glucose and oxygen. Plants use glucose for energy and release oxygen as a by-product. Chlorophyll is what gives plants their green color. It is also found in algae and cyanobacteria for the same function as that of plants. Apart from photosynthesis chlorophyll also helps to protect plant cells from damage by ultraviolet light called photoinhibition of the cells.

Molecular Structure: The chlorophyll molecule is a large, complex molecule composed of a porphyrin ring. The porphyrin ring of chlorophyll is what gives the molecule its distinctive green color. Its structure includes a long carbon-based “tail” and a large “head” group. The head group contains a magnesium atom at its center.

hemoglobin-and-chlorophyll

How Chlorophyll is similar to hemoglobin?

  • Chlorophyll and hemoglobin both have four pyrrole rings.
  • Both chlorophyll and hemoglobin have a central metal ion (Mg2+ for chlorophyll, Fe2+ for hemoglobin) that is essential for their function.
  • The structure of chlorophyll is very similar to that of hemoglobin, with the only major difference being the type of atom that is bonded to the central metal ion.
  • The chlorophyll molecule is distinctly planar, while hemoglobin is more three–dimensional in structure.
  • Due to these significant structural similarities, it is considered that chlorophyll must be having a direct contribution to hemoglobin synthesis.
  • But there are iron-rich plastids (chloroplast) that must be helpful in providing the required iron to the human body on the consumption of green leafy vegetables. Iron is the essential metal ion that actively contributes to hemoglobin production by supplying hemoglobin’s structural component.
featured-heme-chloro

Apart from these important health contribution by chlorophyll it also has many other health benefits

Health Benefits of Chlorophyll

ROS (reactive oxygen species) in the human body: Chlorophyll is a potent antioxidant that can neutralize the damaging effects of ROS. ROS (reactive oxygen species) are a group of chemically reactive molecules that contain oxygen. They have been shown to play a role in a number of human diseases, including cancer and heart disease. They can damage cells and contribute to the development of chronic inflammation.

Cancer Treatment:  Chlorophyll has been shown to have some cancer-fighting properties. Researchers found that Chlorophyll can form a close bond to carcinogenic chemicals called Aflatoxins. When they bind, the Chlorophyll helps to block the absorption of the Aflatoxins (cancer-causing agents) in the intestines.
It is not yet known if chlorophyll can help treat cancer in people. More research is needed to learn more about this possible treatment. Chlorophyll may also help to protect healthy cells from damage caused by radiation therapy.

Improved digestion: Chlorophyll can help stimulate the production of enzymes that aid in digestion and absorption of nutrients.

Detoxification: Chlorophyll may help to remove toxins and heavy metals from the body. It is often used as a natural detoxifier in supplements and juices.

Boosted immunity:  Chlorophyll may help to fight infection and diseases, and boost the immune system. It can also help to reduce inflammation.

Industrial Application of Chlorophyll

In Pharmaceutical
  • Chlorophyll along with many other medicinal components from Alfalfa (Medicago sativa) and silkworm excrement are typically used in medicines.
  • Application of chlorophyll in foul odor removal: When chlorophyll is applied to foul odors, it acts as a natural deodorizer. This magnesium atom is surrounded by four nitrogen atoms. These nitrogen atoms have a strong affinity for sulfur-containing compounds, which are the main cause of foul odors. When the chlorophyll molecule comes in contact with these sulfur-containing compounds, the nitrogen atoms bind to the sulfur atoms, effectively neutralizing the odor.
  • Also, Chlorophyll can be used as a natural dye in the pharmaceutical industry. It can be used in color capsules, tablets, and other pharmaceutical products.
Food and Cosmetics
  • Chlorophyll is a natural colorant that also can be used to add color to food and cosmetics. It is safe and non-toxic and it can be used to create a wide range of colors.
  • Anti-aging remedy: A gel containing chlorophyll to the skin reduced signs of photoaging, which is aging that results from sun exposure. 
  • Acne treatment: A gel containing chlorophyll helped reduce facial acne and large, visible pores.

In the end, we learned that chlorophyll is basically a photosynthetic color pigment that has some structural similarities with hemoglobin. But, it may not be directly contributing to producing hemoglobin after dietary consumption. Rather, the chloroplast which is a photosynthetic plastid contains a high amount of iron, magnesium, zinc, etc. that must be having a significant role in providing metal ions to animals. Chloroplast is the essential iron-rich plant cell organelle and is important for treating iron deficiency and increasing hemoglobin production. Chlorophyll has always been thought to be the essential component of plants that might have a role in hemoglobin production due to its structural similarities, but scientific evidence is not enough to prove it. Therefore, it can be concluded that not chlorophyll as such but chloroplast whole along with chlorophyll, which helps to treat iron deficiency and improves the production of hemoglobin and red blood cells.

Algae- Potential Revolutionizer Of The World

Water bodies, swamps, slippery footpaths, sewers, etc. all are generally laden with green, slimy growth of algae. Such sites usually remain ignored, and perhaps most of the time algae are eradicated to clean the habitats. Why algae are important? How they evolved? What is their role in nature and why even existed throughout billions of evolutionary years? Many questions are there in curious minds. However, algae had played a significant role in developing the earth’s environment to make it suitable for all living creatures. Nevertheless, they are still doing it.

Algae evolved around 3.5 billion years ago as single-cell autotropic creatures, with the ability to synthesize organic food from inorganic resources. Then it colonized all over the earth and even evolved into the varieties of terrestrial plants we see today. During their colonization, they produced a lot of oxygen that paved the way for the evolution of higher organisms. The oxygen produced was the key component that gave the earth its Ozon layer. Further, it protected all the creatures that evolved after it from lethal sunrays.

What are algae and their types?

Algae originated as a single-cell photosynthetic organism, furthermore evolved to form diverse groups of micro and macro species. Their varieties flourished all over the globe in diversified geographical locations. That includes deep sea, hot water springs, soil, deserted locations, ice glaciers to mountain tops. They thrive in marine as well as freshwater in numerous morphological forms. They are classified as Macroalgae and Microalgae. Macro forms include all the seaweed species that grow very large from a few centimeters to several meters and which are eukaryotic. While microalgae are unicellular or multicellular and prokaryotic as well as eukaryotic. The Department of Botany, Smithsonian National Museum of Natural History, has given the following divisions of algae classifications.

Bacillariophyta (diatoms),

Charophyta (stoneworts),

Chlorophyta (green),

Chrysophyta (golden),

Cyanobacteria (blue-green),

Dinophyta (dinoflagellates),

Phaeophyta (brown),

and Rhodophyta (red),

Human interference in nature’s course

Algae play a major role in sequestering environmental pollutants and maintains the balance in global ecosystems. However, their importance was never recognized until this era of global warming. In the last four centuries, industrialization led to the haphazard utilization of natural resources along with fossil fuels. This liberated tremendous anthropogenic carbon dioxide and greenhouse gases into the environment, which is now a consequence of global warming. The human population failed to limit their desires and never participated significantly to play their role in environmental conservation. Moreover, this has given rise to more complex issues including climate change. Global crises related to freshwater scarcity, food and nutritional security, and breaking the deadliest pandemics are some of those.

Multiple options are put forward to deal with this scenario and comprehensive research is being undertaken to tackle the issues. But, none of it has provided the potential permeant solution. World environmentalists, researchers, public leaders, and economists are working on finding alternative options for sustainable development. Sustainability solutions promise to bring some balance to the above-mentioned world scenario.          

How algae will help?

Algal Exploitation has been made for many centuries for a variety of applications for mankind. Oceans are primary in carbon sequestration and algae play a key role in it. Algae-based CO2 sequestration on an industrial scale has proven to be one of the promising ways to deal with climate change. Apart from this, algae are known for their potential applications in wastewater treatment, food, feed and fodder, biofuels, nutraceuticals, biofertilizers, and pharmaceuticals. This has led to the development of the algal biorefinery concept for biofuel and bio-commodity. Successful implementation of this technology will be a remarkable milestone in the process of overcoming many current global issues. Natural selection always defines the fate of any era. Algae thrived in all, supporting another life form all the way. Hence, algae are nature’s potential key players. Man has an opportunity to sustain and revolutionize his future with the help of algae.
