    In this study,NF membrane was used for surface water treatment. The rejection of organic material, measured as Total organic carbon (TOC), by Nanofiltration was examined. The effectsof application ofpre-ozonation and pre-chlorination on TOCremovalare discussedand their performances are compared with the performances ofNanofiltraion system without pretreatment process. In NF, natural organic rejection is high and no pre-treatment are required. Coagulation targetslarge hydrophobic organicswhichfoulNF membranes byprecipitation and gel layerformation. The results showedthat TOC removalin Preozonation-coagulation was higher than prechlorinationCoagulation. In addition pretreatment increases Nanofiltration efficiency.
