Foremost Sewage Treatment Plants in India

Not only India, but the entire world faces the problem of untreated sewage polluting the natural water bodies. However, the work has already begun in India and elsewhere to treat this untreated sewage and make it as much less harmful as is chemically possible. The work is essentially important to establish a comprehensive mechanism that would purify the sewage system and recycle the treated sewage for further industrial utility. There are multiple parameters that should be considered in devising an effective mechanism for sewage treatment in India.

The sewage treatment plants in India work on the parameters of the type of sewage system and the quantity of sewage that needs to be treated. There are many such plants operating in India, but the best among them works through multidisciplinary teams evaluating the chemical nature of sewage and thereby devising effective solutions to the problem of sewage treatment. The final objective is to create a mechanism that would make the treated sewage suitable for industrial recycling, horticultural use or plain safe disposal. In essence, the final objective is to create a recycle system for the sewage and/or safely dispose it causing minimum ecological harm to the natural water resources where the sewage is disposed. 

The sewage treatment plants India work by a set of mechanisms or combination of mechanisms that would be particular to a specific industry. Polluting industries like the textiles, leather, food processing, pharmaceuticals and bulk drugs manufacturing, petrochemicals, mining, power etc have different chemical nature of sewage and the sewage treatment plants India works by devising customized solutions after analyzing the chemical nature of these specific waste disposal systems. 

The mechanisms utilized for the treatment of sewage system in India include a diverse collection of procedures that are used selectively depending on the chemical nature of the waste and the final objective that needs to be achieved. The operational mechanisms may include oil and grease separators, coarse screens, fine screens, pumping stations, grit separators, bioreactors, clarifiers, polishing treatment, disinfection and also advanced treatment methods like ultrafiltration and reverse osmosis. By the effective combination of these methods depending on the nature of sewage, both domestic and industrially polluted effluents can be treated to be rendered useful in a recyclable manner.
