Effluent Treatment Plant (ETP)

Sedimentation The flocs settle at the bottom of a tank, leaving cleaner water on top.

Coagulation and Flocculation These are the initial steps where chemicals are added to raw water to bind particles and impurities, forming larger clumps called flocs.

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
