Abstract: A softening apparatus including an ion exchanger that is repeatedly regenerated using electrolyzed hydrogen ions (H+). The softening apparatus includes a regeneration unit configured to produce regeneration water including hydrogen ions (H+) by electrolyzing water, a softening unit including an ion exchanger regenerated by receiving the regeneration water and configured to convert raw water including hardness components into soft water, and a controller configured to control the regeneration unit to produce regeneration water having a pH of 2 to 4. The ion exchanger has a Si/Al ratio of 1 to 5 and includes an inner pore with a diameter greater than 4 nm.

Abstract: A softening apparatus in which resistance applied between electrodes is decreased to reduce power consumption. The softening apparatus includes a regeneration unit and a softening unit. The regeneration unit includes at least one anode and cathode in a first space which generate regeneration water containing hydrogen ions (H+). The softening unit is disposed in a second space partitioned from the first space and includes an ion exchange body regenerated by the regeneration water.

Abstract: An apparatus for producing reducing water that maintains a neutral range of pH and exhibits superior reducing force. The apparatus for producing reducing water includes an electrolytic bath including a cathode chamber provided with a cathode, an anode chamber provided with an anode, and an intermediate chamber interposed between the cathode chamber and the anode chamber, wherein the cathode chamber and the intermediate chamber are provided with an inlet through which water is supplied, and an outlet through which water is discharged, a cation exchange membrane is provided between the cathode chamber and the intermediate chamber, and the intermediate chamber includes a cation exchange resin that dissociates hydrogen ions when the cation exchange resin reacts with water.
