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： A desalination apparatus includes a pretreatment device (13) having a pretreatment membrane (13a) that filters suspended matters in raw water (11) with added chlorine-containing water (12), a reverse osmosis membrane device (17) having a reverse osmosis membrane (16) that removes a salt content from filtrate water (14) supplied from the pretreatment device (13) to produce permeated water (15), and a reducing-agent injection device (30) that neutralizes the added chlorine on an upstream side of the reverse osmosis membrane device (17). The reducing-agent injection device (30) extracts a part (14a) of the filtrate water (14), adds metering SBS solution (18) to the part, obtains a maximum change point (equivalence point) of the oxidation-reduction potential of a reducing agent and chlorine, obtains reducing-agent additive concentration (Csm) corresponding to the equivalence point, and supplies the SBS solution (18) corresponding to the concentration to the filtrate water (14) to thereby neutralize the chlorine.
