Coagulation in water treatment results in the formation of what?

Coagulation is a critical process in water treatment that involves the addition of chemical coagulants to enhance the removal of suspended particles and impurities from water. During coagulation, these coagulants, typically aluminum or iron-based compounds, neutralize the negative charges of suspended particles. As a result, these particles begin to stick together, forming larger aggregates known as floc.

Floc consists of these combined particles, which can then be more easily removed from the water through sedimentation or filtration processes. This formation of insoluble solids is essential for improving water clarity and quality, making the water safer for consumption and use. Understanding this process is vital for water operators in ensuring effective water treatment and compliance with health regulations.
