Abstract

THE PROCESSING OF LEACHATE WASTEWATER USING ELECTROCOAGULATION METHOD (Eva Febrianti Prihantini, 2014, 51 pages, 12 tables, 19 pictures, 3 appendixes) Leachate is wastewater decomposition of organic waste that is not handled properly and can contaminate soil and groundwater. Contamination by leachate can be reduced, it would require an effort that pollutant levels in the leachate can be reduced before it reaches the ground. One of the methods used is electrocoagulation method. Electrocoagulation is an electrochemical water treatment method where in anoda occured the release of active coagulant as metalic ion, while in cathode occured the electrolysis reaction in a form of the release of hydrogen gas. In this research, the processing of leachate with electrocoagulation method using aluminium electrode has been done with the dimension of electrode 16,5 cm x 7 cm x 0,2 cm. There are some parameter of analysis such as pH, Total Suspended Soid (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Pb, NH3-N, and also 15, 30, 45, 60 minutes of time process variation and 30A/m2, 50 A/m2, 70 A/m2, 90 A/m2 of current density. Optimum conditions and the effectiveness of electrocoagulation for each parameter are in the current density 30 A/m2 with 60 minutes of time process. The effectiveness from electrocoagulation method reduced the value of TSS 46,80%; BOD5 71,33%; COD 73,77%; Pb 62,5%; NH3-N 57,92%; and for the increased of pH from 8,03 to 8,95. Electrocoagulation method can reduce levels of pollutants in accordance with environmental standard. Keywords: leachate, eletrocoagulation, aluminium electrode
