The aims of this research is to produce clean water from Sekanak River by using the ceramic membrane. Also, this study is to analyze the performance of ceramic membranes in terms of its ability to reduce the pollutants contained in water from Sekanak River. The ceramic membrane was tube-shaped, made from clay (87.5 %w), iron powder (2.5 %w) and activated carbon of oil palm empty bunch (10 %w). The operation condition of membrane separation was of 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, 90 minutes and the applied pressure was of 1.0 bar, 1.5 bar and 2.0 bar. The reduction pollutants (Fe, Mn, Zn, NH 3 -N, NO 2 -, PO 4 -3 , H 2 S, BOD 5 , and TSS) concentration increased with increasing the pressure and the operating time of membrane separation. After treating by the ceramic membrane, the average rejection of Fe, Mn, Zn, NH 3 -N, NO 2 -, PO 4 -3 , H 2 S, BOD 5 , and TSS are 81.22%,
