    Abstract: An ion removing system having an ion removing apparatus that includes a fine bubble generating part generating fine bubbles and that causes the fine bubbles to adsorb metal ions to remove the metal ions from the hard water due to supply the fine bubbles generated by the fine bubble generating part into the hard water. In addition, the ion removing system includes a primary-side flow path to supply the hard water to the ion removing apparatus, a separating apparatus that separates crystals of a metal component deposited by crystallizing the metal ions removed from the hard water by the ion removing apparatus, and a secondary-side flow path that takes out, from the separating apparatus, treated water obtained by separating the crystals. The primary-side flow path is provided with a supply-side backflow prevention mechanism.

    Abstract: An ion removal system includes: an electrolysis device configured to generate alkaline water and acidic water by electrolysis; a first flow path and a second flow path through which the alkaline water and the acidic water generated by the electrolysis device are alternately allowed to flow; a hard water flow path connected to the electrolysis device to supply the electrolysis device with hard water; and a fine bubble generation device configured to generate fine bubbles in a flow path upstream or downstream of the electrolysis device, wherein a first flow-rate adjustment valve is connected to the first flow path, and a second flow-rate adjustment valve is connected to the second flow path.

    Abstract: An ion removal system includes: an electrolysis device configured to generate alkaline water and acid water by electrolysis; a hard water flow path to supply the electrolysis device with hard water; a first flow path and a second flow path through which the alkaline water and the acid water generated by the electrolysis device can alternately flow; a fine bubble generation device configured to generate and supply fine bubbles to the hard water flow path, the first flow path, or the second flow path so as to adsorb and remove metal ions in water by the fine bubbles generated; and a controller, wherein the controller controls the electrolysis device to perform a first mode in which the alkaline water is allowed to flow through the first flow path and the acid water is allowed to flow through the second flow path and a second mode in which the acid water is allowed to flow through the first flow path and the alkaline water is allowed to flow through the second flow path.
