Abstract
An ion removing system includes an electrolysis apparatus electrolyzing hard water to generate acidic water and alkaline water; and an ion removing apparatus that includes a hard water storage part storing the alkaline water generated by the electrolysis apparatus and a fine bubble generating part generating and supplying fine bubbles to the hard water storage part and that causes the fine bubbles to adsorb metal ions in the alkaline water in the hard water storage part to remove the metal ions from the alkaline water.
Claims7
An ion removing system comprising:
- an electrolysis apparatus electrolyzing hard water to generate acidic water and alkaline water;
- an ion removing apparatus that comprises a hard water storage part storing the alkaline water generated by the electrolysis apparatus and a fine bubble generating part generating and supplying fine bubbles to the hard water storage part and that causes the fine bubbles to adsorb metal ions in the alkaline water in the hard water storage part to remove the metal ions from the alkaline water;
- a primary-side flow path connected to the ion removing apparatus to supply the hard water to the electrolysis apparatus;
- a separating apparatus connected to the ion removing apparatus and separating crystals of a metal component deposited by crystallizing the metal ions removed from the alkaline water by the ion removing apparatus;
- a secondary-side flow path connected to the separating apparatus to take out, from the separating apparatus, treated water obtained by separating the crystals;
- and
- a return flow path connected to the separating apparatus to return a portion of the treated water containing the crystals to the primary-side flow path.
