Zeolites are used as raw material to make nanofiltration membrane because they are easily obtained and cheap. The used of zeolite membranes can be an alternative wastewater treatment. One of the potential alternatives for wastewater treatment is nanofiltration membranes with pore size of 0.001 μm filtered high organic content of laundry which contained high turbidity and phospate. The content of turbidity and phosphate in the laundry wastewater is needed to treat before being discharged into river. The purpose of this study is to determine the value of rejection and flux for each variation of concentration. Variation of concentration that used were pure wastewater which dilluted with tap water in ratio 100%, 75%, and 50%. Based on this research, the characteristics of laundry waste water before filtration process are turbidity parameters showed for 100%, 75% and 50% are 151 NTU, 146 NTU, 143 NTU and for phosphate parameters are 31.30 mg/L, 25.8 mg/L and 11.49 mg/L. After filtration process, the highest rejection value of turbidity for each dilluted concentrations 100%, 75%, 50% are 88.46%, 87.82%, 87.58%. The highest flux value for each dilluted concentrations 100%, 75% and 50% are 7,22 L/m2.hour, 8,49 L/m2.hour and 11,04 L/m2.hour.
