Abstract: Disclosed is a side stream flow-type reverse osmosis membrane filter with an increased purified water recovery rate. The filter comprises: a filter housing with a raw water port, a purified water port, and a concentrated water port; an RO filter to purify raw water, thereby sending purified water to an inside thereof and discharging concentrated water, which is filtered out; a central tube for collecting the purified water; a raw water pipe arranged in the central tube and provided with a raw water flow channel in a center portion thereof, with a purified water flow channel formed between the raw water pipe and the central tube; and a raw water distributor for supplying supply a portion of raw water to the upper end of the RO filter and a portion of the raw water the lower end of the RO filter and supplying the purified water to the purified water port.
