PROBLEM TO BE SOLVED: To simplify material structure, reduce material cost, processing cost and assembly cost, speed up movement of adsorbed ionic impurities to facilitate removal of adsorbed ions, and also due to swelling and shrinkage accompanying ion exchange reaction. To provide an electric deionized water production apparatus that does not cause poor contact with a single flow or an ion exchange membrane. A DC electric field is applied to a deionization chamber filled with an ion exchanger so that ions to be excluded migrate in the same direction or in the reverse direction with respect to the direction of water flow in the ion exchanger. In the electric deionized water production apparatus that excludes ionic impurities adsorbed on the ion exchanger out of the system, the ion exchanger is a mixture of a monolithic organic porous ion exchanger and a granular ion exchange resin. An electrical deionized water production apparatus. [Selection] Figure 2 |
