| Abstract |
| This study was conducted to evaluate the treatment of copper in wastewater by using electrocoagulation. Most of industrial wastewater has treated to physical and chemical methods because industrial wastewater has biologic toxic. Therefore, electrocoagulation belonging to the electrochemical method is being used in variety of industrial wastewater treatment. It shows mainly high removal efficiency of heavy metal and turbidity. In this study, it was evaluated to copper removal efficiency by pH, reaction time and current density through jar-test experiment. In case of pH, copper concentration was slightly decreased at higher than pH 4. In case of reaction time, copper removal efficiency was 91.6 % at reaction time in 4 minute and more than 98 % at reaction time in after 6 minute. In case of current density, copper removal efficiency was rapidly increased to 0.0058 A/cm2. Base on value of jar-test experiment, continuous operating of electrocoagulation experiment was applied the hydraulic retention time(HRT) 4 minute and current density 0.0167 A/cm2. pH of wastewater was not changed. Results, average copper removal efficiency was 74.7 % and maximum removal efficiency was 79.1 % while operating 110 minute. |
