Polyamine 고분자 응집제의 합성과 상수처리의 적용

Abstract

Polyamine was synthesized for the drinking water treatment. Polyamine was produced by the two step polycondensation of dimethytamine(DMA) and epichlorohydrin(EPI) and its properties were characterized. The effects of mole ratio of (DMA1/1EPl), 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 mg/L of polyamlne flocculant caused the reduction of 50% PAC (polyaluminium chloride).
