How Effluent Treatment Plant (ETP) works?
Coagulation and flocculation. It's a chemical process. Lime, Aluminum Sulfate are mixed with wastewater to destabilize the suspended solid particles in the water. As Alum is mixed with the water, it helps quicker bonding between solid particles and forms large solid particles. Lime is helping to reduce the pH value.
