Description of the Related Art As described in "Chemical Handbook, Applied Chemistry Edition 1" edited by The Chemical Society of Japan (1988, published by Maruzen), pages 196 and 203, ion exchange membranes are used in desalination of seawater and production of salt. The electrodialysis method using is used. In addition, electrodialysis, which does not require regeneration of the resin, has begun to be used instead of the ion exchange resin for the production of deionized water or ultrapure water. That is, as shown in FIG. 1, water containing electrolyte such as seawater or industrial water is passed through a pair of diaphragms, usually between a cation exchange membrane and an anion exchange membrane, and between electrodes arranged on both sides of the membrane. It is a method of applying a voltage equal to or lower than the electrolysis voltage of water to move anions and cations in water through the diaphragm to both sides of the electrodes for desalting. On the other hand, Kubota "New Basic Knowledge of Water" (1993, published by Ohmsha) 80
In the alkaline ionized water production apparatus described on page 82, electrodes are arranged on both sides of a diaphragm composed of a porous membrane or an ion exchange membrane as shown in FIG. 2, and a voltage equal to or higher than the electrolysis voltage of water is applied, N tap water on both sides of the diaphragm
It collects cations such as a ions to make them alkaline, and at the same time, produces water having a low redox potential by electrolysis of water. At the same time, anions such as Cl ~ are collected on the anode side of this apparatus, and electrolysis of water produces acidic water having a high redox potential. As described above, conventionally, an apparatus for producing deionized water only produces deionized water, and an apparatus for producing alkaline ionized water exclusively produces alkaline ionized water and acidic ionized water. It was necessary to purchase both devices in order to obtain both the water and the acidic ionized water, which was uneconomical in terms of price and installation place of the device.
