Popis:	Compact unit system is commercially provided for cut treatment of turbidity and bacteria in water from general source. Equipping with newly developed high performance hollow fiber ultrafiltration (UF) membrane in this system, compact system design can be succeeded to obtain high water quality and very stable operation in long term only with periodical back washing of the hollow fibers. Cellulose Acetate is selected as a membrane material of the hollow fiber in order to give the fiber anti-membrane fauling and easy cleaning natures because of its hydrophilicity. Furthermore high membrane water flux performs well not only on the water production but also on the effective back washing by asymmetric membrane structure designed very highly. This unit system is expected economically benefit from applying to the small and middle classed water purification market.
