Effectiveness of Electrocoagulation Method in Processing Integrated Wastewater Using Aluminum and Stainless Steel Electrodes

Industrial liquid waste is one type of waste that can pollute the aquatic environment. For this reason, we need a method that can be used to treat wastewater by electrocoagulation method. Electrocoagulation is a method of coagulation by using electric current through electrochemical events. In this research, the treated wastewater by electrocoagulation method was integrated wastewater. This process was carried out where wastewater was placed in electrochemical cells containing electrodes with dimensions of 15 cm x 15 cm. Parameters of varied are electrode types of aluminum and stainless steel sensors with varied voltages of 6, 9 and 12 volts, and varied processing time of 30, 60, 90, 120 and 150 minutes. The optimum conditions for the aluminum and stainless steel sensors are 12 volt voltages and 150 minutes process time. The effectiveness of electrocoagulation of integrated wastewater using aluminum sensor was TDS 88.96%, 50% TSS, COD 87.96%, BOD5 52.98%, PO4 35.37%, Fe 62.5% and Pb 85% with efficiency of current 78, 91%. The effectiveness of using stainless steel ensemble was TDS 80.27%, TSS 57.5%, COD 88.43%, BOD5 74.86%, PO4 42.20%, Fe 46.86% and Pb 88.57% with efficiency current 81.25%. The research has fulfilled the environmental quality standard
