Document Type and Number:

WIPO Patent Application WO/2013/018818

Kind Code:

A1

Abstract:

Provided is an electric deionized water production device in which electricity drift in a desalination chamber can be eliminated or reduced. At least one desalination processing unit, comprising a desalination chamber and a pair of concentration chambers disposed on both sides of the desalination chamber, is disposed between a cathode and an anode in the electric deionized water production device. Inside the desalination chamber, anion exchanger layers and cation exchanger layers are layered such that the last ion exchanger layer that water to be treated passes through is an anion exchanger layer; a bipolar membrane is provided on the cathode side of the anion exchanger layers inside the desalination chamber; and anion exchange membranes in the bipolar membranes are in contact with the anion exchanger layers.
