| titleOfInvention | Ion exchange regeneration system for UPW treatment |
| abstract | An improved process for regenerating ion exchange resin, includes a regeneration step of displacing captured ions from the resin to regenerate its ion-capture functionality, followed by one or more fluid-employing post-regeneration steps such as a fluid displacement or rinse, a fluid transport or mixing, and a rinse down to quality. To avoid problems of early leakage of weakly held ions such as boron, the post-chemical or post-displacement steps use water that is essentially free of boron, or otherwise avoid localized contamination in the regenerated resin which is used in bottles or beds. The bottles or beds so regenerated or filled have low leakage, and their useful life can be accurately monitored or predicted by detecting conductivity or boron concentration in the product water. Once a bottle or bed is returned to service, leakage occurs at a detectable level when the unit becomes exhausted. To produce UPW water for regeneration, water may be selected by monitoring the polish beds or bottles for boron breakthrough, and stopping or diverting the product water when or before break-through occurs. A two-stage polish may be operated with modified lead/lag bottles. A detector for an indicator condition (conductivity, silica breakthrough) between stages determines when to shift the lag bottle forward, and periodically both bottles are replaced. Suitable regeneration may also be assured, even in the presence of rinse water carrying problemmatic species, by separating a sacrificial or phantom resin layer. This may be done by applying regenerated fluid treatments (rinses) in a directional flow, and separating the upstream regenerated resin which is thereby contaminated. Separation may be effected using a resin-filled cap or a cartridge that fits over or in-line with the tank or bottle during rinse down to quality. |
