Abstract

See full text

Provided is an electrodeionization apparatus for producing deionized water, capable of removing or reducing a biased flow of electric current in a deionization chamber. In the electrodeionization apparatus for producing deionized water, at least one deionization treatment unit including the deionization chamber and a pair of concentration chambers adjacent to both sides of the deionization chamber is disposed between a cathode and an anode. In the deionization chamber, anion exchanger layers and cation exchanger layers are stacked in an order in which a last ion exchanger layer through which water to be treated passes is an anion exchanger layer. A bipolar membrane is formed on the cathode side of the anion exchanger layer in the deionization chamber. The anion exchange membrane of the bipolar membrane is in contact with the anion exchanger layer.
