Abstract: The present invention relates to a water treatment system for removing at least some of ionic materials included in source water to provide soft water comprising less ionic materials than the source water to a demand source. The water treatment system may comprise: a filter module provided so as to remove at least some of ionic materials included in source water by means of an electrical force to discharge soft water; a supply channel provided so as to supply the source water to the filter module; a discharge channel provided so as to guide the soft water discharged from the filter module to a demand source; a circulation channel branched from the supply channel; a reclaim channel branched from the discharge channel; a connection channel branched from the reclaim channel and connected to the circulation channel; and a descaling part connected to the connection channel and provided so as to provide a descaling material for removing scale to the inside of the connection channel.

Abstract: A water-softening system includes a filter device including filter units that are provided in at least some of a plurality of supply channels arranged in parallel to supply raw water to a consumption site and that remove at least part of ionic matter contained in supplied raw water by electro-deionization and discharge soft water containing less ionic matter than the raw water, a plurality of supply valves provided in the plurality of supply channels to open or close the supply channels, and a processor connected to the filter device and the plurality of supply valves. The processor determines whether water is supplied to the consumption site and controls at least one of the plurality of supply valves to remain open to maintain a state in which water is allowed to be supplied to the consumption site, when it is determined that no water is supplied to the consumption site.
