All over the world, the existing process of water purification needs more flocculants and chlorine due to a gradual decline in the quality of source water. Therefore, the problem of the remaining aluminium and DBPs in purified water is on the rise. To solve this problem, the process of membrane filter has recently come into the spotight. This study reaches the following conclusions concerning TMP variation in order to solve the dropping of flux throgh a membrane filter when operating a membrane filter system in the process of water purification.
1. In case that a cohesion-precipitation process was introduced to pre-treatment of a membrane filter, initial TMP was very satisfactory(0.27㎏/㎝) in producing the constantly safe quality of water, 0.04~0.1(mean 0.05) NTU by pouring 2㎎/1 of PACI(10% Al₂ O₃) used for the existing process of water purification in high-density turbidity at a dry or flood season and at occurrence of high algae.
2. As flux increased at 0.5m/day.m, TMP increased 0.05 ㎏f/㎝.
3. As filtering, operation mode of PVDF MF membrane filtering was 48 minutes and 1 cycle of back washing was 42 minutes, flux was increased 1.5m/day.m and TMP increased 0.25~0.27㎏f/㎝. Without back washing, TMP increased 0.03 ㎏f/㎝ per a cycle.
