    摘要： A water treatment system (1) includes a deionization unit (10) and an ion-selective removing unit (20). The deionization unit (10) includes a pair of opposing electrodes that is charged to have polarities opposite to each other, a flow passageway positioned between the electrodes and enabling passage of water containing ions, and an ion-exchange membrane that is disposed on the flow passageway side of each of the electrodes, and performs a deionization process of deionizing the water containing the ions by allowing the ions to be adsorbed onto the electrodes and a regeneration process of eliminating the ions from the electrodes. The ion-selective removing unit (20) is disposed on the downstream side or upstream side of the deionization unit (10) to separate and remove divalent or more ions from the water containing the ions because the ratio of removing the divalent or more ions that are the scale component among the ions is relatively higher than the ratio of removing monovalent ions from the water containing the ions. The water treatment system (1) can increase the ratio of removing scale component ions.

    摘要： 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.
