Characterization of Leachate at Simpang Renggam Landfill Site, Johor Malaysia

Abstract

Nowadays, the world facing a major problem in managed solid waste due to the increasing of solid waste. Malaysia, one of the country also involves in this matter which is 296 landfills are open to overcome this problem. Currently, the best alternative option to manage solid waste is by using landfilling method because it's have low costing advantages. The negatives side of landfill method, its might cause a pollution by producing leachate that will give an effect to the ground and surface water resources. This study focuses on analyzed the leachate composition at Simpang Renggam Landfill(SRL) site for seven parameter included COD, BOD, SS, turbidity, pH, BOD5/COD, and ammonia (NH3-N). All the data obtained were compared with previous researcher and MEQA (1974). From the result, SRL site was categorized as partially stabilized leachate with the parameter of BOD5/COD > 0.1. SRL site are recommended to use a physical-chemical method for a better treatment because the leachate composition is classified as old leachate and aerated lagoon method are not satisfied to be use in treating the old leachate at SRL site.
