Title:
電気式脱塩装置
Document Type and Number:
Japanese Patent JP4065664
Kind Code:
B2
Abstract:
The object of this invention is to provide an electrical deionization apparatus with which various feed water types ranging from water of high ion concentration to water of low ion concentration can be consistently deionized with high efficiency. At least part of cation-exchange membranes and anion-exchange membranes alternate between electrodes to form an alternating array of deionization and concentration compartments and the deionization compartment contains a woven or non-woven fabric made of cation-exchange fiber that is placed on the cation-exchange membrane side in a face-to-face relationship with a woven or non-woven fabric made of anion-exchange fiber that is placed on the anion-exchange membrane side, with the passageway of feed water between the two woven or non-woven fabrics containing an ion-conducting spacer provided with an ion-exchanging capability.
