PROBLEM TO BE SOLVED: To provide an ion removing system enhancing a metal ion removal effect.
SOLUTION: An ion removing system comprises: an electrolysis device generating alkaline water and acidic water by electrolysis; a hard water flow passage connected to the electrolysis device and supplying hard water to the electrolysis device; a batch processing tank mounted in the middle of the hard water flow passage and housing the hard water; a return flow passage connected to the batch processing tank so as to return the alkaline water or the acidic water generated by the electrolysis device to the batch processing tank; and a fine bubble generator generating fine bubbles in a circulation flow passage including the batch processing tank, the electrolysis device and the return flow passage, and adsorbing metal ions in the water by the generated fine bubbles to remove the metal ions from the water.
