Abstract
PURPOSE: To convert original water into pure water with high efficiency at lower cost by providing heater for entering water into reverse osmosis device before the front coagulating filter of reverse osmosis device.
CONSTITUTION: Fresh water used in the manufacture of semiconductor integrated circuit, etc., is manufactured by converting industrial water, well water, etc. In this case, the heater 21 is arranged at the front stage of the coagulating filter 11, and the original water W is heated to approx. 25°C and passed through the coagulating filter 11 to remove impurities, colloidal substances, etc., and then through reverse osmosis device 14 to remove impure ions, etc., to obtain the pure water Wp. The heating of the original water Wo before the coagulating filter 11 in this way prevents post-sedimentation and also blinding of the reverse osmosis device 14, permitting the production of pure water with high efficency and at lower cost.
