From the above figure 2 chitosan ,dosage, between 12 mg/l– 30 mg/l, % reduction of COD increases. From 30 – 66 mg/l, the % reduction of COD decreases due to electrostatic repulsion of colloidal particles based on charge density effect. The optimum chitosan ,dosage, for effective coagulation and flocculation process is 30 mg/L.
