Document Type and Number:
WIPO Patent Application WO/2015/163632
Kind Code:
A1
Abstract:
Disclosed is a reverse osmosis membrane filter for raising a purified water recovery rate by increasing a supply amount of raw water to a reverse osmosis membrane sheet. According to the present invention, provided is a side stream flow-type reverse osmosis membrane filter comprising: a filter housing provided with a raw water port, a purified water port and a concentrate water port; an RO filter for subjecting raw water to a water purification treatment, thereby discharging the purified water to the inside direction and discharging the filtered concentrated water to the outside direction; and a central tube for collecting inside thereof the purified water, to which the purification treatment has been subjected by the RO filter, via through-holes formed in the radial direction, wherein a raw water moving tube, formed to be spaced apart from the inside of the central tube, forms a raw water moving passage in the center thereof, and forms a purified water moving passage between the raw water moving tube and the central tube; and a raw water distributor, mounted on the top end of the raw water moving tube and the central tube, supplies water to the raw water moving tube to supply a part of the raw water to the top end of the RO filter and supply a part of the raw water to the bottom end of the RO filter, and supplies the purified water, collected in the purified water moving passage, to the purified water port.
