Abstract : The electrocoagulation studies of distillery spentwash using copper anodes were utilized to demonstrate the usefulness of Box–Behnken experimental design of response surface analysis to derive a statistical model and the optimum parameters for color removal. The current intensity (1.5 A), dilution (10%) and time of electrolysis (5 h) had been found to be the optimum conditions for maximum 77.11% color removal. The actual color removal at optimized conditions was found to be 78.26%, which is to the predicted response using response surface methodology. The energy consumption and current efficiency were determined from reduction in chemical oxygen demand.
