摘要：An apparatus for producing deionized water comprising an electrodialyzerhaving cation exchange membranes and anion exchange membranes alternately arrangedbetween a cathode and an anode to form demineralizing compartments andconcentrating compartments, and ion exchange resin particles packed in the
demineralizing compartments, wherein the ion exchange resin particles are a mixture ofat least two groups of ion exchange resin particles having a particle size distribution suchthat particles having particle sizes of from 75 to 125% of the average particle size, are atleast 85 wt % of the total amount, and the average particle size of a group of ionexchange resin particles having the maximum average particle size, is at least 1.5 timesthe average particle size of a group of ion exchange resin particles having the minimumaverage particle size.
