Wastewater Treatment

The water which flows down the drain after being used is called wastewater. It contains various impurities. Most of the cities have a complicated network of sewer lines which finally ends in a reservoir. Before releasing the wastewater into a water body, it is necessary to treat wastewater. Wastewater treatment plants use various physical, chemical and biological processes to purify water. Once wastewater is treated thoroughly, it is channelized into the water body.
