Most of the ground water in Indonesia region contain iron (Fe) and manganese (Mn). The Water which contain the iron and manganese can’t be used directly for daily consumption. This problem can be solved using porous ceramic based membrane. <br /> <br /> <br /> In this research, the synthesizing process of calcium aluminosilicate or zeolite is done by using direct foaming method. The purpose of using zeolite ceramic based membrane is to reduce the metal content contained in groundwater. The membrane is added with activated carbon in order to reduce the turbidity and odor of the ground water. Bonding agent used in this research is geopolymer made from metakaolin, sodium silicate with NaOH 12 M as the activator. <br /> <br /> <br /> Material characterization techniques used in this research are XRD, SEM, FTIR, BET dan water quality test. Data gained from XRD indicates that zeolite used in this research is mordenit which has calcium as it’s cation. Data(s) gained from SEM shows that macropores are not spreaded evenly. The FTIR spectra shows the geopolymer as the bonding agent is succesfuly formed. Ground water used has a rate of 7.74 NTU turbidity, iron content (Fe) of 0.852 mg / L, the content of manganese (Mn) of 2,082 mg / L. Water quality testing that has been done shows sample A could reduce the turbidity of 2.15 NTU to 5.59 NTU, reducing the Fe content of 0.236 mg / L to 0.616 mg / L, and reduce the content of Mn to 0.596 mg / L. Water filtration results using sample B has a rate of 5.36 NTU turbidity, Fe content of 0,580 mg / L, Mn content of 0.327 mg / L. Water filtration results using sample C has a turbidity of 3.48 NTU, Fe content of 0,270 mg / L, and Mn content of 0.480 mg / L.
