Abstract

Leachate or three years old active landfill was identified to have a very low biodegrability (low BOD/COI). Ozone-based on Advanced Oxidation Process (AOI') techniques have been currently developed by utilizing heterogeneous catalysts. This study treated leachate from an active landfill with the O:/ H:0 2 with addition of natural zeolites as catalysts. It was done lo show some effect of natural zeolites mass to accelerate the formation of OII-; the response of leachate matrices; and the effectiveness of the process. The study was conducted on a semi-batch rc11ctor with volume of 500 mL. Oxygen from the ambient air was supplied using an aerator into ozone generator to produce ozone al rate of 3 L/min. Al the ozone contactor ozone was contacted with 250 mL of leachate samples and 1.197 g / L Ih0 2. The addition of zeolite was done by varying its mass at O 5 grams, 2.5 grams and 4.5 gram inside the ozone contactor. The results showed that the pH increased gradually. The best results were shown on the addition of 4.5 gram zeolites (AOP-K- 4.5) which was capable of removing as much as 23% electrical conductivity, 57.14% turbidity, 28.68% organic aromatic as UV254 and 88.89% COD. The results showed, the more zeolites was added the higher the removal efficiency, but in this study the addition of optimum mass of zeolites was not yet have been found.
