the process of returning a column to its original ionic form after use. Regeneration is carried out by eluting the column with a concentrated solution of the desired ion.

The displacement from the ion exchange resin of the ions removed from the process water. In the water softening process, when most of the sodium ions have been replaced by hardness ions, the resin is exhausted and must be regenerated. Regeneration is achieved by passing a concentrated NaCl solution through the resin tanks, replacing the hardness ions with sodium ions. The regeneration process can be repeated indefinitely without damage to the resin provided the incoming water has been properly filtered and by following the correct procedure.

That part of the operating cycle of a water softener in which a sodium chloride solution is rinsed through the cation exchange bed to remove hardness ions and prepare it for a service run.

Passing a concentrated brine (salt) solution through the resin, which removes the calcium and magnesium, replenishing the sodium.

The process during which the water softener re-charges the resin particles contained in the mineral tank.

The method by which exhausted ion exchange resins are reactivated by treatment with strong acid or alkali.

Includes backwash, brine and fresh water rinse steps necessary to prepare a water softener exchange bed for service after exhaustion.

a water conditioner's cleaning cycle; the cycle prepares the system's resin bed so it can soften water again

In ion exchange applications, the use of a chemical solution (regenerant) to displace the contaminant ions deposited on the ion exchange resin during the service run and replace them with the kind of ions necessary to restore the capacity of the exchange medium for reuse.
