摘要：The aim of this work was to treat wastewater from industrial pulp and paper recycling using electrocoagulation. Aluminum (Al) and Iron (Fe) electrodes were used as the electrochemical cell set up. Factors of initial pH and initial voltage were tested during the process and optimized. Tests were done on different initial pH values of 5, 7 and 9 and initial voltage levels of 20, 40 and 60 mv. All samples were analyzed according to standard methods. Result showed that initial pH 7 and initial voltage 60 mv had better removal efficiency for COD and color removal. In these conditions, COD and color removal efficiency with the Fe electrode were 92% and 100%, respectively. Al electrodes had lower efficacy for COD and color removal than the Fe electrode.
