Abstract: An ion removal system includes: an electrolysis device configured to generate alkaline water and acid water by electrolysis; a hard water flow path connected to the electrolysis device to supply the electrolysis device with hard water; a batch treatment tank provided in the hard water flow path to store the hard water; a return flow path connected to the batch treatment tank to return the alkaline water or the acid water generated by the electrolysis device to the batch treatment tank; and a fine bubble generation device configured to generate fine bubbles in a circulation flow path including the batch treatment tank, the electrolysis device, and the return flow path, the fine bubble generation device being configured to adsorb and remove metal ions in water by the fine bubbles generated.

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.
