| The purpose of this research is to investigate characteristics of landfill leachate treatment by the existing leachate treatment system which consists of nitrification and denitrification processes, biofilm treatment process, flocculation-sedimentation process, sand filtration process, and granular activated carbon (GAC)adsorption process and to evaluate the effect of the advanced treatment system added membrance process to the existing system in terms of wastewater reuse. The results presented that the removal rate of the existing system were than 95% for BOD, COD, SS, and Nitrogen, while the efficiency of Cl^- and Ca^(2+) removals was relatively low as approximately 20%. Added membrane process-electrodialysis to the GAC beds, Cl^- and Ca^(2+) removals were very effective as more than 98% of removal rates. Therefore, this indicates that the application of the reuse of treated water by advanced treatment system the existing system plus the membrance process is feasible. |
