6 Laboratory Exercise Acceleration of Settling Rates by Coagulants 

Coagulation and flocculation are used to increase the effective particle size, thereby improving sedimentation settling rates. Coagulation produces 

Five or six 1-L measuring cylinders are required. A concentrated suspension of a fine powder, for example, limestone or starch in water, is also necessary. Any known coagulant agent, such as Al2(S04)3 or Fe2(S04)3.
