DIRECT REVERSE OSMOSIS MEMBRANE WATER PURIFICATION APPARATUS WITH REGENERABLE REVERSE OSMOSIS MEMBRANE

摘要

[Problem] To provide a reverse osmosis membrane water purification apparatus in which the capacity of a used reverse osmosis membrane can be regenerated. [Solution] A direct reverse osmosis membrane water purification apparatus (100) for forming purified water (63) from raw water (61) is provided with: a reverse osmosis membrane module (20); a raw water supply line (25a) connected to a raw water supply port (25) of the reverse osmosis membrane module (20); a permeate line (24a) connected to a permeate port (24); and a concentrated water line (23a) connected to a concentrated water port (23). The concentrated water line (23a) is provided with a flow adjustment valve (64) (valve (64) with a resistance (64a)) and a rinsing water line (54) through which rinsing water (55) passes is connected to the permeate port (24) of the reverse osmosis membrane module (20).
