    Abstract: An improved system of resins comprising a combination of a sulfate-specific strongly basic anion exchange resin and a heterogenous hybrid thermally regenerable salt sorbent (TRSS) resin is provided. The anion exchange resin contains triethylamine and/or tributylamine groups. The TRSS resin comprises a macroporous host copolymer and a crosslinked guest copolymer having, respectively, weak acid groups and weak base groups. The system is used to treat feed water containing dissolved ions, including sulfate ions, and is efficiently regenerated.

    Abstract: A treatment system passes feed water containing a contaminant such as perchlorate through a bed of strong base anion exchange resin that has been placed in a form (e.g., in sulfate form) to selectively capture the contaminant while passing other ions (e.g., nitrate) that may also be present in the water. The bed selectively removes the perchlorate with high efficiency, for example on a stoichiometric basis, until exhaustion. The bed operates robustly without spiking or displacement of more weakly-held or lower affinity ions as composition of the feed varies. The water may be further treated, if necessary, to produce a purified or potable product, in which case downstream processes may remove remaining contaminants and co-ions. Alternatively, the treated stream may be returned to or blended with the source to effect contaminant remediation, e.g., site clean-up. Contaminants such as uranium species, perchlorate or pertechnate may be treated by this method using ordinary (non-specialty) exchange resins. The bed may include a carousel, and the exhausted upstream portion of the resin may efficiently be disposed of by incineration, or may be rotated out for regeneration. Alternatively, the bed or the spent portion thereof may be periodically regenerated transferring perchlorate to a regeneration fluid waste. The concentrated waste may be disposed of by incineration, bioreaction or other suitable disposal process. The concentrated regen waste may also be passed through a smaller, sacrificial bed of ion exchange resin to capture its perchlorate, allowing re-use of the regen fluid and forming a lower-volume solid waste output. This second-bed re-transfer process operates efficiently at the high concentration present in spent regen fluid, and requires only a small fraction of the original bed volume.

    Abstract: A new method is described to produce large volumes of low cost sterile, Water-for-Injection (WFI) grade water on-line, on-demand from potable water in order to meet the needs of dialysis therapies and other biological applications for sterile, injectable grade water. The source water is processed by a combination of membrane and column chromatographic methods including reverse osmosis, chemical sterilization, reduction of iodine sterilant to iodide, deionization, endotoxin-specific adsorption and polishing filtration in order to reduce contaminant levels below those specified by the US Pharmacopoeia.

    Abstract: A chemical distribution system having improved organic solvent fluid purity and consistency includes a vessel containing ion-exchange media positioned within a fluid flow pathway such that the organic solvent fluid passes through the ion-exchange media, thereby effecting removal of undesired impurities. Different embodiments of the invention position the vessel at varying locations within the fluid flow pathway. The chemical distribution system also preferably includes a return chemical flow pathway that recirculates purified organic solvent fluid through the ion-exchange media-containing vessel and thereby enables the system operator to conduct incremental adjustment of the solvent purity until a desired overall purity is attained.
