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.

摘要： One purpose of the present invention is to provide a system for producing a magnesium chloride aqueous solution, said system making it possible to further reduce drug-related costs compared to conventional methods. The present invention relates to a system for producing a magnesium chloride aqueous solution, said system comprising: a crystallization unit that adds a sodium hydroxide aqueous solution to to-be-treated water consisting of seawater as a feedstock material, and generates a reaction slurry having magnesium hydroxide particles dispersed therein; a precipitation unit that stores the reaction slurry, and causes the precipitation of particles to separate the reaction slurry into recovered slurry and a separated liquid; a removal unit that removes divalent positive ions from the to-be-treated water or separated liquid, and generates a reaction liquid; an acid-alkali generation unit that generates a sodium hydroxide aqueous solution and hydrochloric acid from the reaction liquid; and a reaction unit that adds the hydrochloric acid to the recovered slurry, and generates a magnesium chloride aqueous solution. The acid-alkali generation unit includes: a main unit that generates the sodium hydroxide aqueous solution and the hydrochloric acid from the reaction liquid; a first connection unit that supplies the sodium hydroxide aqueous solution to the crystallization unit; and a second connection unit that supplies the hydrochloric acid to the reaction unit.

摘要： In a method of desulfurization used at a geothermal power plant, stem removed from a production well, after being used for power generation, is condensed and separated into condensed water and hydrogen sulfide-containing gas, and the hydrogen sulfide-containing gas is treated at biochemical treatment tank. The initial cell density of the reactor liquid of the biochemical treatment tanks is adjusted by cell culture liquid obtained from a cell breeding culture tank provided independently of the biochemical treatment tanks and water or a part of hot water returning to a reduction well, hydrogen sulfide-containing gas is supplied thereinto and desulfurized thereat. With lowering of activation at the biochemical treatment tanks and with lowering of desulfurization ability there, the acidified reaction liquid is removed and is added to the hot water returning to the reduction well. Accordingly, addition of inorganic nutritive salt for cell breeding becomes unnecessary. A geothermal power plant desulfurization system is constructed so that cells are separated by use of a cell separation filter from the acidified reaction liquid removed from the biochemical treatment tanks and the cells so separated are returned to the biochemical treatment tanks.

摘要： Provided is a water treatment system in which the ratio of removal of ions of a scale component can be increased. A water treatment system is equipped with: a pair of electrodes (11, 13) which face each other and can be electrically charged so as to have opposite polarities to each other; an interelectrode flow path (15) which is arranged between the electrodes (11, 13) and through which water containing ions can flow; and ion exchange membranes (12, 14) each of which is arranged on the interelectrode flow patch (15) side of each of the electrode (11, 13) and enables the ions to flow to the electrode (11, 13) side. The water treatment system is also equipped with a desalination unit (10) in which a desalination treatment for adsorbing the ions onto each of the electrodes (11, 13) to desalinate the water and a regeneration treatment for desorbing the ions from each of the electrodes (11, 13) are carried out. One (14) of the ion exchange membranes enables bivalent cations, which are contained in the water containing the ions, to selectively flow to the electrode (13) side.
