The laundry wastewater produced by laundry service becomes a pollutant of the water. The main characteristics of laundry wastewater are a high value of BOD dan COD. This research is aimed to study the utilization of ceramic hybrid membranes for laundry wastewater treatment. The ceramic hybrid membrane was produced from natural zeolite that coated with polyvinyl alcohol (PVA). The results show that the average percentage of the decreasing value of BOD reaches 83.37% and the average percentage of the decreasing value of COD is 89.86%. Based on turbidity, the higher rejection is obtained at the pressure of 5 bars with the value of rejection of 96.85%.
