Which method of water treatment is used to remove turbidity?

The method of water treatment used to remove turbidity is coagulation and sedimentation. This process involves adding chemical coagulants to the water, which causes small particles and impurities to clump together, forming larger aggregates known as flocs. These flocs then settle to the bottom of the treatment container during the sedimentation phase, effectively clearing the water of suspended particles that contribute to turbidity.

Coagulation and sedimentation are essential for improving water quality as they not only reduce turbidity but also help in removing pathogens and various contaminants. While filtration is also a method that can reduce turbidity, it primarily serves to filter out particles after they have been clumped together. Chlorination and boiling are methods focused on disinfection rather than turbidity reduction, targeting the elimination of microbes rather than the physical clarity of the water.
