Treatment of Paint (Emulsion) Industry Wastewater by Electrocoagulation

Abstract

Treatment of paint industry (emulsion) wastewaters by electrocoagulation using different electrode materials has been investigated in this paper. Several working parameters, such as pH, current density, operating time, types of electrodes and surface area were studied in an attempt to achieve a higher COD removal capacity. The electrolytic cell used was a 500 ml cylinder glass reactor with working volume 400 ml and equipped by magnetic stirrer without temperature control. The DC power supply was controlled by a voltmeter. The study also revealed that electrocoagulation with Al electrodes was more effective than MS and SS electrodes.
