Abstract :
Electrocoagulation is the process destabilization of suspensions, emulsions and solutions containing contaminan by means of electric with electrodes in water, causing the formation of clods that easily separated. This study aims to determine the level of efficiency decreased Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) contained in industrial wastewater Cold Storage after electrocoagulation process. This research was conducted in the laboratory by batch method using industrial waste from Cold Storage. Electrodes used are aluminum with a variation of a distance of 4 cm and 8 cm using variable sampling time 60, 120, 180 minutes. From this research obtained the best results with a variable voltage 18 volts, the sampling time 3 hours and a distance of 4cm electrode to reduce maximum COD of 1000 mg / liter with an efficiency decrease of 66.7% and a decrease in TSS of 40 mg / liter with an efficiency decrease 97.50% . Based on the results obtained for COD reduction not meet the standard of quality standards set by the S.K.Gubernur Jawa Timur No.45 th.2002.
