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 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 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) separates and removes 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.

摘要： A suspended-matter removing method and a suspended-matter removing apparatus are disclosed that require no sludge treatment facility, and inexpensively provide filtrate satisfying a water quality standard. The suspended-matter removing method includes: feeding a protrusion element to a filter layer formed by filling a solid filter material, adding a protrusion to a surface of the solid filter material; after feeding protrusion element, determining whether a protrusion has been added to the surface of the solid filter material, and when it is determined that the protrusion has been added, reducing a feeding amount of the protrusion element as compared with when adding the protrusion; forming a biofilm on the surface of the solid filter material; and passing water to be treated containing suspended matters through the filter layer having the solid filter material added with the protrusion in a state in which the feeding amount of the protrusion element is reduced.
