(57) [Abstract] [Problem] To simplify the structure of the device, material cost, processing cost, Provided is an electric deionized water producing apparatus that reduces assembly costs and has no possibility of generating scale such as calcium carbonate and magnesium hydroxide. SOLUTION: Water is passed through a deionization chamber filled with an organic porous ion exchanger having a three-dimensional network structure to remove ionic impurities in water to produce deionized water, and a DC electric field is applied to the deionization chamber. In the electric deionized water producing apparatus for removing the ionic impurities adsorbed on the organic porous ion exchanger out of the system by applying the DC electric field, the ions to be removed are applied to the organic porous ion exchanger. The electrophoresis is performed so that the electrophoresis is performed in a direction opposite to the direction of water flow in the exchanger. |
