Application of membrane filtration for large–scale drinking water treatment plant has been significantly expanded in recent years. In addition, development of membrane module for small–scale decentralized water treatment plants is also required. We have developed the submerged membrane module that adopts a PVDF hollow fiber membrane, suitable for the decentralized water treatment plants. By using the lake water, pilot test was conducted with the developed module for membrane performance evaluation. The raw water quality was varied with seasons and rain fall. We demonstrated continuous stable filtration for 6 months under the condition of constant flux (1.2 m3/m2/d) and water recovery rate (98%).
