Electrochemical Treatment of Oily Wastewater Using Three Dimensional Steel Wire Electrodes

Electrochemical technologies have been successfully applied for the removal of heavy metals, dyes, organics and oils from wastewater. In the present study, a sample of wastewater containing cutting oils were treated by applying potential difference to the electrodes, which were formed by two beds made of steel wire pieces. In order to improve separation efficiency different forms of electrode beds were tested. In addition, the experiments were performed by using steel plate electrodes under same operating conditions. The electrode configurations were compared depending flow characteristics, turbidity and COD removal efficiencies. The residence time distribution experiments were performed in the analysis of flow. The separation efficiency was also discussed based on operating parameters such as the strength of applied voltages, electrode area, pH, conductivity and volumetric flow rate. The highest attained turbidity and COD removal efficiencies were 85% and 80%, respectively, in the experiments. It has been observed that similar turbidity and removal efficiencies can be achieved with the use of the bed of steel pieces electrodes rather than plate electrodes by consuming less energy.
