Abstract: Coagulation and flocculation are two of the most common chemical treatment methods used in wastewater treatment. The objective of this research is to study the effectiveness of coagulation-flocculation method for the color removal from industrial wastewater by using a different type of coagulants. In this research, we had study and compare the five types of coagulants that were used in past experiment which are Magnesium Chloride (MgCl2), Aluminium sulphate (Alum) and Polyaluminium Chloride (PAC), Ferric Chloride (FeCl3) and Ferrous Sulphate (FeSO4) to remove Remazol Black B (RBB), Remazol Brilliant Blue (RBBR), Remazol Brilliant Red F3B (RBRF3B), leachate, Disperse Red 60 (DR 60) and Brilliant Green (BG) dye. As the coagulant aid, polyelectrolyte, Koaret PA 3230 and Praestol was used. To obtain the optimum condition of the highest color removal of reactive dye, this research focuses on the effect of pH, coagulant dosage, settling time and mixing time. Among all the studies, we have come to a conclusion and conclude that PAC was the most effective coagulant in treating each dye with the color removal among the coagulants used.
