Poly(DADM) was synthesized for the drinking water treatment. Poly(DADM) was produced by the free radical polymerization of diallyldimethylammonium chloride(DADM) monomer and its properties were characterized. The effects of monomer concentration, initiator concentration and reaction time on synthesis of poly(DADM) were investigated. Poly(DADM) flocculant was applied to Nak-dong river water to examine its efficiency in reducing turbidity. The synthesized poly(DADM) was effective as flocculant for drinking water treatment. The addition of 1 ㎎/L.of poly(DADM) flocculant caused the reduction of 50 % PAC(polyaluminium chloride).
