An electrochemical method in conjunction with chemical coagulation and ion-exchange treatment is employed to treat the wastewater effluent from a large chemical fiber plant. The effectiveness of the combined methods in treating the wastewater effluent was assessed in terms of water quality for reuse in the manufacturing process, Experiments were conducted to examine the effects of various operating variables of the electro-chemical method, chemical coagulation and ion exchange on the water quality and the optimum operating ranges of those variables were identified. The quality of wastewater effluent after the combined treatments was found to be excellent, better than the reuse standards for the chemical fiber industry.
