Which treatment method is primarily used to reduce turbidity in water?

Flocculation is a treatment method specifically designed to reduce turbidity in water by promoting the aggregation of suspended particles into larger clusters, known as flocs. This process involves the addition of chemical coagulants, such as alum, which help destabilize the particles suspended in the water column. Once the particles agglomerate into heavier flocs, they can then be removed more easily from the water through sedimentation or further filtration processes.

The effectiveness of flocculation in addressing turbidity is vital for improving water clarity and quality, making it a key step in water treatment. Other methods, while useful in the overall treatment process, do not primarily target the reduction of turbidity as their main function.
