    摘要： A method of reclaiming spent aqueous brine solutions used in the regeneration of water-softening resins is disclosed. An aqueous chloride or other brine solution is acidified with HC1 to a pH of between about 0.5 and 6 and a soluble sulfate salt, preferably Na2SO4 is added, together with a precipitation inhibitor of the type polyacrylamide. Following such treatment, the spent brine is pumped at high pressure axially through a spirally-wound nanofiltration-type membrane device which is effective to remove at least about 90 % of the divalent hardness while allowing passage therethrough of at least about 90 % of the monovalent cations. As a result of such treatment, about 90 to 95 % of the volume of spent brine can be efficiently and effectively reclaimed in a form in which it is suitable for use again in regenerating water-softening resins or the like.

    摘要： An improved method for regenerating ion exchange resin in a treatment tank having a flow direction, which includes the steps of providing a supply of regenerant under pressure into the tank, and introducing the regenerant into the tank in an opposite flow direction to the treatment flow direction. In the preferred embodiment, the regenerant is a combination of CO 2 which is mixed with water to form carbonic acid and citric acid. This mixture is then introduced into the treatment tank without storage.

    摘要： The invention relates to a device for regenerating an ion exchange cartridge. In household appliances with an electric heating element for heating water, such as irons, coffee makers, and electric water kettles, deposition of scale is prevented by using an ion exchange cartridge (16) comprising a resin (23) which binds alkaline earth metal ions such as Ca?2+ and Mg2+¿, but also negative ions such as SO¿4?2- and CO¿3?2- ions. The device is a simple tool in which the cartridge can be inserted for regeneration. The device comprises a reservoir (2) with an outlet (10) to which an inlet (6) of the cartridge can be coupled. By filling the reservoir with a brine, for example 1 l of water with 10 % by weight of NaCl, said brine will flow through the cartridge replacing the alkaline earth metal ions, carbonate ions, and sulfate ions in the resin with the alkali metal ions (Na+) and the chloride ions (Cl-) of the brine. The brine can be easily drained into a sink.
