The Use of Electrocoagulation Technique for Paper Mill Wastewater Treatment

Abstract:

Electrocoagulation technique has been widely used in wastewater treatment because it is considered as safe, efficient and environmentally friendly. In this research, electrocoagulation cell was constructed using aluminum and iron electrodes. These metal plates were cut into three parts and were arranged in parallel modes. The constructed electrocoagulation cells were then utilized for the treatment of wastewater obtained from local paper industry. Some operational parameters namely electrolysis time, pH, applied voltage, and electrode distance were analyzed. It was found that the optimum conditions were electrolysis time of 60 minute, pH of 7, applied voltage of 14 V and electrode distance of 1.5 cm. For iron electrode, percentage removals of conductivity, turbidity, COD and BOD were 62%, 97%, 37% and 30%, respectively. For aluminum electrode, the percentage removals of conductivity, turbidity, COD and BOD were 42%, 98%, 37% and 50%, respectively.
