Although membrane filtration plants were introduced to purification plants in recent years, prevention from Cryptosporidium, pollution of tap water source, rationalization of management, etc is still remarkable. And those 84% of all are small-scale plants which treatment capacity is less than 1,000m^3/d. Recently, it is considered that membrane filtration plant will be introduced for more large scale plant where it is necessary to conserve energy and achieve space saving system. Authors are now studying the establishment of large capacity membrane system with energy and space saving by introducing monolith ceramic MF membrane. Until now, TMP has been stable at Flux 4m/d for about three months in a small-scale test plant.
