In this study, the optimization of electrochemical oxidation techniques for textile wastewater treatment was experimentally investigated. After some preliminary study using copper and stainless steel were chosen as the best anode and cathode respectively. The effect of operational parameters such as supporting electrolyte (sodium chloride) concentration, initial pH and electrolysis time on pH changes and percentage of color, chemical oxygen demand (COD), biological oxygen demand (BOD), total organic carbon (TOC) were determined. The optimum range for each of these operating variables was experimentally investigated. The result obtained show that the percentage of color, COD, BOD, TOC in aqueous phase was removed effectively. Under the optimum operating conditions, sodium chloride concentration of 0.1 M, initial pH 7.67, electrolysis time of 105 minutes, percentage of color and COD removal efficiency reached 96.2%, while for BOD, TOC, removals the percentage is slightly lower.
