Abstract: PURPOSE: Provided are an ultra-pure water manufacturing device and a method for manufacturing ultra-pure water by using the same which recover treated water to a raw water supplying tank or automatically control the discharge amount of the supplied treated water and concentrated water when the salt removing rate is abnormal compared to the reference value. CONSTITUTION: The device(1) comprises a pre-treating filter(7) primarily filtering fine particles contained in raw water supplied from a raw water supplying tank(3), a first reverse osmotic membrane device(11) removing salts contained in the water filtered through the pre-treating filter, a second reverse osmotic membrane device(13) removing salts contained in the concentrated water separated by the first reverse osmotic membrane device, a salt removing rate tester(19) installed on a treated water supply line(15) to check the salt removing rate of the treated water, a treated water supply valve(21) equipped at the treated water supply line to switch on and off the treated water supply line, a return valve(25) opening and closing a return line(23) connected from the treated water supply line between the treated water supply valve and the second reverse osmotic membrane device to the raw water supply tank, a concentrated water control valve(29) equipped at a concentrated water discharge line(27) where the concentrated water separated by the second reverse osmotic membrane device passes through and a controller(31) comparing data regarding the salt removing rate checked by the salt removing rate tester to generate an opening and closing signal of the treated water supply valve, return valve and concentrated water control valve.
