What happens to the solids during flocculation?

During flocculation, solids in water clump together to form larger aggregates, or flocs. This process typically involves the addition of chemicals known as flocculants, which help to neutralize the charges on suspended particles. As these particles collide, they stick together more easily, resulting in the formation of larger and heavier aggregates that can subsequently be removed through sedimentation or filtration.

The process is a critical step in water treatment, as it improves the efficiency of subsequent processes like sedimentation and filtration, allowing for clearer water and the effective removal of contaminants. Understanding the mechanism of flocculation is essential for those working in water treatment facilities, as it directly impacts the quality of the final water product.
