%X Copper in effluent from an etching process was removed by a combined process of electrodialysis and ion exchange. The closed system made the treated water(less than 1mg/L Cu) reuseable and provided a way of recovering the metallic copper by using replacement reaction with scrap iron. The system was operated smooth without deposition of copper on the cathode or the ion exchange membrane. The escape of chlorine gas from the anode chamber was provented. The energy consumption was less than 3kWh per cubic meter wastewater treated and the cost for metallic copper recovery was about 1 yuan per kilogram.
