<p><P>PROBLEM TO BE SOLVED: To provide a means for stably supplying water suitable for drinking by using a reverse osmosis membrane and silver zeolite together. <P>SOLUTION: The water purifying method includes making water to be treated pass through the reverse osmosis membrane, adding cations (excluding silver ions) to the water to be treated which has passed through the reverse osmosis membrane, and bringing the water to be treated, to which the cations are added, into contact with particles containing the silver zeolite. In the method of manufacturing drinking water, the water to be treated is purified by the water purifying method. For the water purifying device and the method of manufacturing the drinking water, the reverse osmosis membrane and a silver-zeolite-containing particle filling part are provided. Between the reverse osmosis membrane and the silver-zeolite-containing particle filling part, a cation addition means for adding the cations (excluding the silver ions) to the water to be treated which has passed through the reverse osmosis membrane is included. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
