This research has been done to determine the effectiveness of nylon 6,6- kaolin hybrid membrane in reducing the intensity of peat water color . The effectiveness of membrane can be known from membrane permeability and selectivity. Membrane permeability of nylon 6,6-kaolin hybrid was 2x10-5 mL/cm2s bar . Application of nilon 6,6-kaolin hybrid membrane for treating peat water color at various pressures showed a good membrane performance in reducing the intensity of the color ranges from 97-99%. Decrease in color intensity was the highest at a pressure of 1.5 bar . Nilon 6,6-kaolin hybrid membrane effectively was used in treatment peat water. Quality of membrane processed peat water is in compliance with clean air standards by PERMENKES No.492/MENKES/PER/IV/2010 about drinking water quality requirements.otherNylon 6,6 membrane -kaolinPeat waterPermeabilityOther
