Top 10 Wastewater Treatment Companies in India

 

Wastewater, often also called sewage, is the polluted water that is formed as a result of human activities or rainwater runoff. Historically, such water was released into naturally occurring water bodies without much treatment. However, with increasing population and industrialisation, the pollution caused by human activities has increased. Thus, it has now become necessary to treat wastewater before it is released into the environment to avoid diseases and harm to humans as well as other organisms.

The process of wastewater treatment involves removing all the physical and chemical pollutants in the water to make it safe to use. This process protects the environment and reduces the strain that continuous human use creates on waterbodies.

The following are the leading companies providing wastewater treatment services to protect the environment and ecology of India.

Three Reasons Why Waste Water Treatment is Important

 

Waste Water Treatment is the process of removing any pollutants and contaminants from wastewater (also called sewage) and returning it to the environment. It involves removing all physical, chemical, and organic pollutants that contaminate the water. 

What happens if wastewater is left untreated?

If wastewater is dumped in natural water bodies untreated, the excess nitrogen, phosphates, and rotting organic matter in the sewage can cause abnormal plant growth. These plants then secrete toxins that deplete the oxygen in the water, leading to ‘dead zones’ – areas where no aquatic life can exist. Thus, untreated wastewater can make water bodies uninhabitable. 

The reasons why wastewater treatment is so essential to conserve our environment include:

The natural wastewater treatment process is overburdened 

Nature has its own ways of treating wastewater that end up in water bodies. However, with a population boom in the last two centuries and the rapid industrialisation of human society, we now produce more wastewater than nature can handle. This has caused significant strain on the aquatic ecosystems. This strain has made it necessary for humans to actively aid the natural process of wastewater treatment. 

Wastewater treatment facilities are designed to mimic these natural processes and thus reduce the harm caused to the environment. 

Protecting human life

Untreated wastewater released into rivers, lakes and streams also contaminates the drinking water supply for many people. The toxins can cause many deadly diseases in human beings. 

According to Cole-Palmer, unclean water causes 1.7 million deaths annually. 90% of these deaths take place in developing countries. It can also cause diseases such as Typhoid Fever, Gastroenteritis, E-Coli Diarrhoea, Encephalitis, Hepatitis A, and Cholera among others. 

Wastewater treatment can save human lives and improve the quality of life for people, especially in developing countries. 

Protecting natural ecosystems

As mentioned earlier, untreated wastewater can significantly alter underwater ecosystems. This can lead to a ripple effect in the food chain. Pollutants in natural water sources can contaminate aquatic plants and the fish that eat them. The polluted fish can in turn cause harm to the humans and animals that eat them. 

Wastewater can end up contaminating entire ecosystems if left untreated. Thus, wastewater treatment facilities not only save human and aquatic life but also end up preserving the environment. 

How is wastewater treated?

The process of wastewater treatment involves three stages – primary, secondary and advanced. The primary stage involves the screening and settlement of large particles. 

In the secondary stage, bacteria are introduced to break down the organic matter polluting the wastewater. Then, it is usually treated with chlorine to remove any remaining bacteria. 

The advanced stage is specific to the particular regions where the plants are based. It involves removing any particular pollutant, like nitrogen or phosphorus, which is of concern to that particular region. The purified water is then allowed to flow into local water bodies. 

As a developing country, India is no stranger to the damage that untreated wastewater can cause. Shapoorji Pallonji Group has been helping Indians overcome these perils for decades. With more than 145 billion litres of wastewater treated across India, Shapoorji Pallonji Group has helped improve the lives of Indians.

Common Wastewater Treatment Solutions

Water treatment is an important aspect to consider, no matter how we lead our lives. The water we use for various purposes can become an undesired by-product after use. This water can also contain harmful substances that could adversely affect humans, animals, and the aquatic environment. Proper treatment of used water is a responsibility for everyone to undertake.

In this article, we will understand some common ways of wastewater treatment.

What is wastewater treatment?

It is a process that removes contaminants and harmful substances from the water before releasing the water into the water cycle. The wastewater treatment process makes it possible for proper water treatment so that it can be reused.

Why is wastewater treatment necessary?

Wastewater treatment is necessary for many reasons. Some of them are:

• Protection of human health
• Protection of the environment
• Water conservation
• Compliance with regulations

What are some methods of wastewater treatment?

Some methods of wastewater treatment are as follows:

• Physical Treatment: Physical treatment involves removing large solids from the wastewater through processes such as screening and sedimentation.
• Biological Treatment: Biological treatment uses microorganisms to break down organic matter in wastewater through processes such as activated sludge, trickling filters, and anaerobic digestion.
• Chemical Treatment: Chemical treatment involves the use of chemicals such as chlorine, ozone, and hydrogen peroxide to disinfect the wastewater and remove contaminants.
• Membrane Filtration: Membrane filtration uses special filters to remove contaminants from the wastewater through microfiltration, ultrafiltration, and reverse osmosis.
• Advanced Oxidation Processes: Advanced oxidation processes use chemicals such as hydrogen peroxide and ozone to break down contaminants in the wastewater.
• Constructed Wetlands: Constructed wetlands are artificial wetlands designed to treat wastewater. The wetlands use natural processes to remove pollutants from the wastewater.
• Thermal Treatment: Thermal treatment involves heating the wastewater to high temperatures to destroy contaminants through processes such as incineration and pyrolysis.

These are just a few examples of wastewater treatment solutions available. Shapoorji Pallonji is known worldwide for top-quality resource creation to support safe access to water through effective wastewater treatment solutions. Shapoorji Pallonji has installed over 50 wastewater plants, with the iconic Malabar Hill Reservoir built in 1887.
