ClarificationThe suspended matter can consist of large solid, settleable by gravity alone without any external aids, and non-settleable material, often colloidal in nature. ?Steps of ClarificationCoagulation Reduction of the surface charge of suspended solids and, reduction of forces of mutual repulsion results in the agglomeration of the particles. Flocculation The addition of a relatively small quantity of flocculating agent, consist of polymer of long chain containing active groups results in the agglomeration of the individual particles.
