APPARATUS FOR MANUFACTURING REFINED WATER

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing refined water capable of reducing the stagnation of water in the apparatus with lesser energy and of suppressing the propagation of bacteria and the generation of endotoxins. SOLUTION: This apparatus for manufacturing the refined water has a softening means for softening raw water and a refining means for filtering the softened raw water by a reverse osmosis membrane to obtain the refined water. The refining means consists of a reverse osmosis membrane module 12 having a raw water inlet through which the softened raw water is introduced, a refined water outlet through which the resulted refined water is discharged, and a concentrate outlet through which the concentrate unpermeated through the reverse osmosis membrane is discharged. The raw water inlet side and the concentrate outlet side are connected by a circulation line 91 provided with a circulating pump 90 for circulating the liquid. COPYRIGHT: (C)2004,JPO
