RO MODULE HAVING EMBEDDED CHECK VALVE AND WATER PURIFING SYSTEM HAVING SAME

摘要

The present invention relates to a water purifying system having a RO module having an embedded check valve, which stores purified water processed by the RO module in a storage tank and discharges the purified water to use if necessary. According to one embodiment of the present invention, the water purifying system having an RO module having an embedded check valve comprises: at least one pre-processing filter for filtering foreign substances in raw water supplied from a raw water supply source; a side flow type RO module for purifying raw water which has passed through the pre-processing filter and introduced to a side of a reverse osmosis membrane wound in a form of a bag to be moved in a longitudinal direction so as to separate the purified raw water into purified water and concentrated water and to discharge the same; a storage tank for storing the purified water which is purified by the pre-processing filter and the RO module; an automatic shutoff valve (ASV) for moving the raw water supplied from the raw water supply source to the pre-processing filter, and shutting off inflow of the raw water into the pre-processing filter when a pressure of the purified water stored in the storage tank exceeds a set value; a check valve embedded in an outlet of a central tube of the RO module, and preventing the purified water of the storage tank from flowing backward to a concentrated water side of the RO module when the pressure of the purified water stored in the storage tank exceeds the set value; and a water discharge unit connected to the outlet of the central tube and discharging the purified water discharged from the storage tank.;COPYRIGHT KIPO 2018
