PURPOSE:To enhance flashing effect, by performing the flashing of a RO membrane by transmitted water in a transmitted water tank arranged at a place higher than a RO module. CONSTITUTION:A transmitted water tank 18 is arranged at a place higher than a RO module 8 in the output side of said module to receive transmitted water C sent out from the RO module 8. When a RO membrane 9 was clogged in usual operation, a fifth valve 17 is opened and a sixth valve 19 is closed while a seventh valve 20 is fully opened to return a raw solution (a) from the RO module 8 to a second tank 4. At the same time, transmitted water C in the transmitted water tank 18 is sent into the RO module 8 under pressure by the head with the RO module 8 through the seventh vale 7 and a booster pump 5 to wash off the contaminant on the RO membrane 9 by transmitted water C having a high purified degree and easy to penetrate into the RO membrane 9.
