Abstract

This study was carried to investigate the effect of humic acid and kaloin which cause the turbidity and organic substance component for optimization of drinking water treatment process using the membrane separation. Also we were ovserved the optimum operating condition which flux was stabilized, while specific resistance value in membrane was minimized. As the result, the membrane separation was operated at low specific resistance value with the increase of the pressure. And then, cake load decreased by high velocity with the increase of the linear velocity, and the tendency in which specific resistance value and flux increased. Therefore, we confirmed the optimum operating condition as pressure $2.0 kgf/cm^2,$ 0.92 m/sec linear velocity.

분리막을 이용한 정수처리 공정의 최적화를 위하여 유기물 성분인 humic acid와 탁도를 유발하는 kaolin을 모사 용액으로 제조하여 막내 비저항 값을 최소화하면서 flux의 안정된 경향을 나타내는 최적의 운전 조건을 검토하여 보았다. 그 결과 압력이 증가함에 따라 낮은 비저항값에서 효율적인 분리막을 운전할 수 있으며 선속도가 증가함에 따라 높은 전단율에 의해 cake load는 줄어들었으며 이에따라 비저항값과 flux는 증가하는 경향을 나타내었다. 따라서 최적의 운전조건은 압력 $2.0 kg_f/cm^2,$ 선속도 0.92 m/sec으로 알 수 있었다.
