Introduction to Coagulation and Flocculation

Coagulation and flocculation are used to remove particulate impurities (especially non-settleable solids) and color from the water being treated. Most surface waters require treatment of this type before distribution to the consumer. Turbidity and bacteriological stands must be met when treating surface water, but color from oxidation of inorganics such as iron and manganese in the water may be primarily aesthetic.
