What is the process of coagulation in water treatment?

Coagulation is a crucial process in water treatment that involves the addition of chemicals to the water. These chemicals, known as coagulants, serve to destabilize the colloidal particles and suspended solids present in the water. When coagulants are introduced, they create small aggregations by binding these particles together, forming larger clumps known as flocs. The formation of these flocs facilitates the subsequent sedimentation and removal of these impurities during the water treatment process.

This step is essential in enhancing the efficiency of filtration and ensuring that the water meets safety and quality standards before distribution. By effectively binding suspended particles, coagulation helps in reducing turbidity and eliminating contaminants, contributing to the overall effectiveness of the water treatment process.
