WATER PURIFING APPARATUS

摘要

PURPOSE: An apparatus for purifying water is provided to filter metal ions included in raw water using a filtration membrane module, to solve problems that an ion exchange resin and an adsorber are frequently replaced and to prevent the holes of a reverse osmosis membrane from being blocked. CONSTITUTION: An apparatus for purifying water includes a contact layer module(30) which is arranged on the upstream of a filtering device The contact layer module is arranged within a pipe-shaped housing(31) and includes a plurality of hollow fiber type contact layers(32). The contact layers transmit gas without transmitting a liquid. Raw water, which is supplied from a raw water supply source, is injected into the filtering device. A part of oxidation inducing gas is contained in the raw water as dissolved gas.
