- 摘要:
PROBLEM TO BE SOLVED: To improve the efficiency of filtration with a reverse osmosis membrane by beforehand reducing endotoxin in raw material water before reverse osmosis treatment for obtaining purified water used for an artificial dialysis solution.
SOLUTION: In water treatment method for producing purified water by passing water to be treated through a reverse osmosis treatment apparatus 4 comprising reverse osmosis membranes, an electrolyzer 2 is installed which has a working electrode 11 where a diamond thin film is formed on a substrate, and a counter electrode 13 facing the working electrode 11 so as to leave a space of 0.05 or 1.0 mm between them, and uses the space as a passage of the water to be treated, a voltage less than a voltage causing water electrolysis is applied between the working electrode 11 and the counter electrode 13 to electrolyze the water to be treated, and the water to be treated whose endotoxin content is reduced to 1,000 unit/L or less is supplied to the reverse osmosis treatment apparatus 4.
