Abstract

LEACHATE TREATMENT USING ADVANCE OXIDATION PROCESS BY OZONE. Landfilling technique gives negative impact due to its leacheate formation. Leacheate treatment in Indonesia is insiginificant because being dominated with biological system. This research aim is to find the effectivity of ozon process and its advance oxidation. Leacheate sample came from the inlet of the installation from Sarimukti Landfill which is being dilluted 10 times. The variation consists of O3, O3/H2O2 0.6 gr/L and O3/UV. The process runs for 3 hours with sampling every 30 minutes. The result shows that the leacheate have ratio of BOD/COD of 0.2. DHL values for three variations are decreasing with the same range of 8-11%. The highest efficiency removal came from the combination of O3/H2O2 0.6gr/L. Meanwhile the highest COD removal efficiency comes from O3/H2O2 28.9%. The excallation of BOD is given by variation of O3 and O3/UV which can be indicates that the process has been successfully to increase the biodegradability of leacheate. The H2O2addition and UV exposure plays as an initiatior to the decomposition of ozone which formed the OH· as the highest oxidator in water to enhance the better oxidation process. Meanwhile the complexity of leachate needs to be investigated further to shows its composition of organic compounds.
