Wastewater Treatment


It is astounding how for over centuries we have been exploiting available natural resources creating scenarios of acute scarcity. Water is no exception to this practice and we have now hit upon a point-of-no-return! Reuse and recycling has emerged as credible solutions to surmount the problems of water scarcity.

Wastewater treatment is gaining popularity as a source of usable water in different countries across the globe. In India, where the disparity in demands and supply is extremely high, wastewater management can be revolutionary with its economic benefits and importance as a coping strategy for the poor.

Wastewater treatment and reuse augments water scarcity giving a dependable and sustainable resource for applications requiring large volumes of water consumption. It has transformed into an indispensable solution to meet the water demand not just in the residential segments but also for agriculture, irrigation and industrial operations.

In India, large volumes of wastewater are discharged unprocessed by industries and the available sources for treatment of domestic and industrial wastewater are underutilized. EverythingAboutWater has been constantly aiming at imparting information on the practical methods for wastewater management that may be adopted by various industrial units. Our publication and training sessions focus exclusively on which type of wastewater treatment plants and methods would be suitable for usage by multiple segments all parts of the country.

There are a variety of operations available for wastewater treatment. Each method has to be combined in the most efficient possible manner to achieve technically, economically and ecologically viable solution for a complete wastewater management system. To define these operations, a wastewater treatment specialist would refer his tool-box with:
