    • PROBLEM TO BE SOLVED: To provide a water treatment system using reverse osmosis membrane, which can precisely and safely suppress the occurrence of fouling in a reverse osmosis membrane used for purifying water.SOLUTION: The water treatment system includes: a first flow meter; an ultraviolet irradiating lamp; an ultraviolet dose controller; a high-pressure pump; an electrolytic apparatus; and a reverse osmosis membrane module. The first flow meter measures the flow rate of water to be treated. The ultraviolet irradiating lump irradiates the water to be treated with ultraviolet rays. The ultraviolet dose controller controls the dose of the ultraviolet rays by the ultraviolet irradiating lamp based on the measured flow rate of the water to be treated. The high-pressure pump boosts the pressure of the water to be treated after irradiated with the ultraviolet rays. The electrolytic apparatus has electrodes for generating copper ions or active oxygen for electrolyzing the water to be treated. The reverse osmosis membrane module passes the electrolyzed water to be treated through for removing solute.
