Performance on humic acid removal from natural organic matter using Nanofiltration (NF) has been investigated in this study. Since most of the organic matter in groundwaterhas smaller between 200-500 D of the pore sizes, the useof the NF process was proposed. Thin-film composite nanofiltration membranes were prepared via interfacial polymerization of triethanolamine and trimesoyl chloride with different concentration and reaction time. The separation process was conducted by separating solution that contains humic acid to get the best result based on varying the concentration and reaction time for interfacial polymerization. In term of concentration of monomers has shown that 4% TEOA has gives more rejection of humic acid. As for reaction time, meanwhile10 minutes of TMC reaction time shows higher performance in removing humic acid. Fouling is still occur because of the tendency of humic acids appears to be dueto their ability to bind to multivalent salts. 0aMembrane separation 0aSewagexPurification  00104071a10000b10000d2019-09-04l0oTP248.M46 N87 2012 rs Bc.p0000074950r2019-09-04 00:00:00t1w2019-09-04yPSM  00104071a10000b10000d2019-09-04l0oCD 7175 | TP248.M46 N87 2012 rs Bc.p0000074951r2019-09-04 00:00:00t1w2019-09-04yPSM  aVIRTUA40c3932d3938  aVTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5020*5040*5200*6500*6501*9992
