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.
