Title:
WATER SOFTENER
Document Type and Number:
Japanese Patent JP2023034382
Kind Code:
A
Abstract:
To provide a water softener which can suppress degradation in regeneration efficiency of other ion exchange resin generated by completion of regeneration processing of one ion exchange resin, in regeneration processing of a weakly acidic cation-exchange resin and a weakly basic anion-exchange resin.SOLUTION: A water softener 1 includes a water softening tank 3, a neutralization tank 4, and an electrolytic cell 9. The electric cell 9 generates acidic electrolytic water for regenerating a weakly acidic cation-exchange resin 7 and alkaline electrolytic water for regenerating a weakly basic anion-exchange resin 8. The water softener 1 has an acidic electrolytic water circulation flow channel 40 for circulating and distributing the acidic electrolytic water in the electrolytic cell 9, a first discharge port 13, the water softening tank 3, and a first water intake 12 in this order, and an alkaline electrolytic water circulation flow channel 44 for circulating and distributing the alkaline electrolytic water in the electrolytic cell 9, a second discharge port 17, the neutralization tank 4, and a second water intake 16 in this order.SELECTED DRAWING: Figure 1
