Performance of filter media depended on both of the surface area and surface activities. Since, the surface area will be determining the numbers of contaminants, and the surface activities will conclude the types of contaminant that can be adsorbed. The surface area will be highest if the particle sizes were reduced. However, reducing the particle size will influences to the filtration rate. The research has been conducted for small particle size (<106 ,um) of carbon and silica sand. Then to optimize the filtration rate and strengthening the media, granulation process were done before the press-forming. Such that, water will through the media by both the inter-granular and trans-granular pores. The filter media were processed by varying the composition of additive (PVA-PEG 400 solution) in percent weight, as: 20%, 25%, 30%, 35%, and 40%.<p>TDS test on water filtered with activated carbon shows that the numbers of parameter are increase by increasing the additive composition, in the range of 360 mg/L to 560 mg/L. For Fe-Mn test conducted on activated silica filtering water showing a constant value of Fe content, that is <0.042 mg/L. But, the Mn content was decreased in the additive composition increased, by range of 0.829 mg/L to 0.687 mg/L. Flexural-strength test for carbon membrane shows that the strength was increase with increasing the additive composition, by range of 1.05 MPa to 2.09 MPa. In the other hand, the strength of silica’s membrane was decreased by the additive composition increased, in the range of 1.67 MPa to 0.23 MPa.
