Abstract: The present invention generally relates to purification systems, and to sanitization and/or sealing of the purification system. The purification system includes an electrodeionization device which can comprise one or a plurality of stages. The electrodeionization device can be constructed with a resilient sealing member forming a water-tight seal between rigid thermally and dimensionally stable compartment spacers. The construction of the electrodeionization device may allow cycling of hot water and/or other liquids, which, in some cases, can improve efficiency and performance of the electrodeionization device. Moreover, the cycling of hot water and/or other liquids may be used to sanitize the electrodeionization device to at least a pharmaceutically acceptable condition and, preferably, in certain instances, to meet at least minimum requirements according to U.S. Pharmacopoeia guidelines by inactivating any microorganisms present within the electrodeionization device.

Abstract: An apparatus and process for removing strong oxidizing agents from liquids. An exemplary embodiment of the apparatus includes an inlet for receiving an input stream having a first concentration of a strong oxidizing agent. The input stream flows into an irradiation unit in fluid communication with the inlet. While resident in the irradiation unit, the input stream is irradiated with UV radiation to substantially reduce the first concentration, thereby forming a first product stream having a second concentration of the strong oxidizing agent. The first product stream then passes through a treatment unit in fluid communication with and positioned downstream of the irradiation unit where the second concentration is substantially reduced, thereby forming a second product stream having a third concentration of the strong oxidizing agent. The treatment unit is selected from the group consisting of a softener unit, a reaction vessel containing a bed of metal redox media, and combinations thereof.
