WIPO Patent Application WO/2019/167335
Kind Code:
A1
Abstract:
An ion removing system according to the present invention is provided with: an ion removing apparatus that is provided with a microbubble-generating part for generating microbubbles and removing metal ions in hard water by causing the metal ions in the hard water to be adsorbed to the microbubbles by supplying the microbubbles generated by the microbubble-generating part to the hard water; a primary-side channel for supplying the hard water to the ion removing apparatus; a separating apparatus that causes the metal ions removed from the hard water by the ion removing apparatus to crystalize and that separates the precipitated crystals of the metal components; and a secondary-side channel for removing the treated water, from which the crystals have been separated, from the separating apparatus, wherein the primary side channel is provided with a supply-side backflow preventing mechanism.
