Title:
WATER SOFTENER
Document Type and Number:
Japanese Patent JP2023093807
Kind Code:
A
Abstract:
To provide a water softener which suppresses catalyst degradation and is capable of maintaining an electrolytic performance for an extended period.SOLUTION: A water softener 1 includes: a softening tank 3 for performing water softening treatment on raw water; a neutralization tank 4 for neutralizing pH of soft water passed through the softening tank; an electrolytic tank 9 for generating acidic electrolytic water and alkaline electrolytic water; and a control part 26 for controlling resin regeneration treatment for performing at least one of the regeneration of a weakly acidic cation-exchange resin 7 using acidic electrolytic water or the regeneration of a weakly basic anion-exchange resin 8 using alkaline electrolytic water. Also, the electrolytic tank 9 includes: a first chamber 76 having a first electrode 77; a second chamber 14 having a second electrode 11 and neighboring with the first chamber 76 via a diaphragm; and a third chamber 18 having a third electrode 15, not neighboring with the second chamber 14, and neighboring with the first chamber 76 via a diaphragm. Also, the control part 26, on resin regeneration treatment, allows the first electrode 77 and the second electrode 11 to function as an anode and allows the third electrode 15 to function as a cathode.SELECTED DRAWING: Figure 1
