Abstract
Ion removing system includes primary-side ion removing apparatus that includes primary-side hard water storage part storing hard water and primary-side fine bubble generating part generating and supplying fine bubbles to primary-side hard water storage part and that causes fine bubbles to adsorb first metal ions in hard water in primary-side hard water storage part to remove first metal ions from hard water, secondary-side pH adjustment apparatus increasing pH of hard water from which first metal ions are removed by primary-side ion removing apparatus, and secondary-side ion removing apparatus that includes secondary-side hard water storage part storing hard water having pH increased by secondary-side pH adjustment apparatus and secondary-side fine bubble generating part generating and supplying fine bubbles to secondary-side hard water storage part and that causes fine bubbles to adsorb second metal ions in hard water in secondary-side hard water storage part to remove second metal ions from hard water.
