<p>In order to enable the production of high-purity deionized water and inhibit scale formation, an electric device for producing deionized water is provided with at least one desalination treatment unit, said desalination treatment unit being provided between a cathode chamber (E1) and an anode chamber (E2), and being formed from a desalination chamber (D) and a pair of concentration chambers (C1, C2) which are provided on both sides of the desalination chamber (D) and into which an anion exchanger is filled. The desalination chamber (D) is partitioned, by an ion exchange membrane, into a first small desalination chamber (D-1) which is adjacent to one side of one of the concentration chambers (C1), and a second small desalination chamber (D-2) which is adjacent to the other concentration chamber (C2); the anion exchanger is filled into the first small desalination chamber (D-1), and the anion exchanger and a cation exchanger are filled into the second small desalination chamber (D-2) in an order such that the last ion exchanger through which the water which is undergoing treatment passes is the anion exchanger; and on the cathode side of the anion exchanger filled into the second small desalination chamber (D-2) a bipolar membrane (4a) is arranged in an orientation such that the anion exchange membrane surface thereof faces the anion exchanger.</p> |
