Studies were conducted on the synthesis, characterization and water ultrafiltration properties of a composite membrane consisting of a thin silver film supported on the outer surface of a porous ceramic cylinder. The support was obtained by slip-casting using materials easier to prepare and less expensive than commercial supports, Ag films were coated on the surface of support using electroless plating and cathodic electrodeposition techniques. Cross-flow ultrafiltration was used to treat water from a public water supply. The experimental results indicated the efficiency of the composite membrane. Treatment quality was evaluated on removal turbidity, heterotroph plate counts and humics as determined by removal of substances absorbing UV light at 254 nm.
