<P>PROBLEM TO BE SOLVED: To prevent a reverse osmosis membrane from contaminating with microbes in a water processing device using the reverse osmosis membrane. <P>SOLUTION: The water processing device consists of a reverse osmosis membrane module, and a supply pump for supplying processed water to the module and/or a high-pressure pump. A column in which a contact material for removing phosphorus in water is filled is disposed upstream of the supply pump and by passing an entire amount of processed water through the phosphorus removing column, the concentration of phosphorus in the processed water is reduced and phosphorus is supplied to the reverse osmosis membrane. <P>COPYRIGHT: (C)2012,JPO&INPIT |
