Abstract
Landfill leachate is a serious problem during treatment of municipal solid waste using landfill method. Less attention has been paid for the treatment of this leachate while this leachate is usually highly polluted. This study investigated the performances of nanofiltration membrane for treatment of landfill leachate (from Semarang, Indonesia). Landfill leachate was treated using NF99 nanofiltration membrane (pore size 200 Da). Synthetic leachate was used in this research which follows the characteristics of real leachate. Microfiltration (MF) membrane was used as a pretreatment before Nanofiltration (NF). The effect of pressure on membrane performance was observed. The membrane performance was examined for permeate flux and membrane rejection for TSS, TDS, and COD then compared to the effluent quality of existing leachate treatment. The rejection of COD, TSS and TDS were 96, 100 and 62%, respectively. The results suggest that the effluent had much better quality than the existing installation leachate treatment.
