Pengolahan Leachate Tempat Pembuangan Akhir Sampah Menggunakan Kombinasi Teknologi Membran Mikrofiltrasi Dan Nanofiltrasi

(LANDFILL LEACHATE TREATMENT BY USING COMBINED TECHNOLOGY OF MICROFILTRATION AND NANOFILTRATION MEMBRANE)Landfill leachate treatment in Jatibarang still use the conventional system which consist of collecting pond, anaerobik pond, aerobik pond, sedimentation pond, and then discharge into the Kreo River. However, the effluent of this treatment still unqualified the permitted standard. The landfill leachate treatment by using combined technology of microfiltration and nanofiltration membrane has been chosen due to the ability to reduce Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) and its ability to remove divalent heavy metal content (Mulder, 1996). This study has been conducted to analyze the difference two type of membranes (NF99HF, NF99) on varied pressure (4, 5, 6 kg/cm2). Furthermore, the membrane performance stated by calculate the value of permeate flux and the ability to reduce COD, TSS, and Iron. According to the analysis, almost all of the parameter has reached the quality standard on Perda Prov. Jawa Tengah No. 5/2012. Optimum condition reached by membrane NF99 at 4 kg/cm2 pressure. The rejection on membrane NF99 at 4 kg/cm2 pressure are 94,22% (COD), 58,69% (TSS), and 99,72 (Total Iron). Over all, the effluent by using combined technology of microfiltration and nanofiltration membrane has better quality than used existing installation leachate treatment
