| Abstract |
| The electrochemical treatment is considered as one of the advanced oxidation processes, potentially a powerful method of pollution control, offering high removal efficiencies in compact reactors with simple equipments for control and operation of the process. The treatment process would be relatively non-specific, that is, applicable to a variety of contaminants but capable of preventing the production of unwanted side-products. In recent years there has been a growing interest in the treatment of industrial effluents by electrochemical methods as an alternative to traditional biological treatments. In this study, 2-step electrochemical treatment system which is made up electrochemical coagulation, electrochemical oxidation was developed for treatment of wastewater. Objectives of this study are develop lab-scale wastewater treatment system using electrochemical technology and evaluate organic pollutants removal efficiency. In the lab-scale test, 95% of SS was removed and removal efficiency of COD, TOC was above 90%, also. It means the 2-stage electrochemical system is effective on removal of organic pollutants, especially suspended solids. |
