APPARATUS FOR PRODUCING DEIONIZED WATER |
摘要 |
An apparatus for producing deionized water comprising an electrodialyzer having cation exchange membranes and anion exchange membranes alternately arranged between a cathode and an anode to form demineralizing compartments and concentrating compartments, and ion exchange resin particles packed in the demineralizing compartments, wherein the ion exchange resin particles are a mixture of at least two groups of ion exchange resin particles having a particle size distribution such that particles having particle sizes of from 75 to 125% of the average particle size, are at least 85 wt% of the total amount, and the average particle size of a group of ion exchange resin particles having the maximum average particle size, is at least 1.5 times the average particle size of a group of ion exchange resin particles having the minimum average particle size.
