Polyamine was synthesized for the drinking water treatment. Polyamine was produced by the two step polycondensation of dimethylamine(DMA) and epichlorohydrin(EPI) and its properties were characterized. The effects of mole ratio of [DMA]/[EPI], reaction temperature and reaction time on synthesis of polyamine were investigated. Polyamine flocculant was applied to Nak-dong river raw water to examine its efficiency in reducing turbidity. The synthesized polyamine was effective as flocculant for drinking water treatment. The addition of 1 ㎎/L of polyamine flocculant caused the reduction of 50% PAC (polyaluminium chloride).
