Wastewater treatment technology that commonly used is coagulation-flocculation. This method has weakness in processing costs and volume of sludge. Therefore, we use alternative method that more effective than coagulation-flocculation, it is electrocoagulation method. Electrocoagulation is a coagulation method using an electric current through an electrochemical reaction. The work principle of electrocoagulation is dissolving metal anode (M+) which then reacts with hydroxyl ions (OH-) that form a coagulant. The waste that will be processed by using this electrocoagulation method is an integrated liquid waste. This reseearch was conducted in a batch where the liquid waste will placed in an electrochemical cell which has the electrodes with dimensions of 15 cm x 15 cm. The parameters in this method will be varied. They are the type of electrodes, electrode aluminum and stainless steel and a voltage of 6, 9 and 12 volts, and the process time 30, 60, 90, 120 and 150 minutes. The optimum conditions for the aluminum electrodes and stainless steel was the voltage of 12 volts and processing time of 150 minutes. Effectiveness of the electrocoagulation to treat the integrated wastewater by aluminum electrodes are TDS 88.96%, TSS 50%, COD 87.96%, BOD5 52.98%, PO4 35.37%, Fe 62.5% and Pb 85% with a current efficiency of 78,91%. For the effectiveness of using stainless steel electrodes are TDS 80.27%, TSS 57.5%, COD 88.43%, BOD5 74.86%, PO4 42.20%, Fe 46.86% and Pb 88.57% with current efficiency 81.25%. The results of this research have fulfilled the enviromental quality standards.
