A Study on Treatment of Wastewater using Electrochemical Oxidation Techniques

Electrochemical oxidation process has gained increasing interest due to its exceptional technical features to eliminate a wide range of pollutants exist in various types of wastewaters, e.g., refractory organic matter, nitrogen species, microorganisms, etc. Serve as a clean, adaptable and powerful tool in removing pollutants, this review paper focuses on the fundamental mechanisms of electrochemical oxidation process and provides discussions on the possible applications in wastewater treatment. Electrochemical technique is suitable for the removal of various pollutants from industrial wastewater. The effect of electrolytic treatment on the properties of different effluents was evaluated. Three different electrodes namely iron, aluminium and steel were used. Three factors pH, voltage and time were varied in each experiment and the results were evaluated on the basis of COD and metal removal efficiency.
