flocculants and coagulants

Flocculants and Coagulants

Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping colloids apart.
