Abstract: An electrical purification apparatus and methods of making same are disclosed. The electrical purification apparatus may provide for increases in operation efficiencies, for example, with respect to current efficiencies and membrane utilization. The methods comprise preparing a cell stack for the electrical purification apparatus to provide a first fluid flow path or compartment and a second fluid flow path and compartment that is in a direction different from the first flow path.

Abstract: Electrochemical devices and methods for water treatment are disclosed. An electrodeionization device (100) may include one or more compartments (110) containing an ionselective media, such as boron-selective resin (170). Cyclic adsorption of target ions and regeneration of the media in-situ is used to treat process water, and may be driven by the promotion of various pH conditions within the electrochemical device.

Abstract: An indicator system for use on a medicine bottle to indicate the times and dates of the last dosage taken and the next dosage to be taken, including means for registering time and date when the bottle is opened and then closed.

Abstract: Systems and methods for process stream treatment. The treatment system may generally include an oxidation unit coupled to a downstream demineralization unit. The oxidation unit may oxidize organic and reduced sulfur contaminants in the process stream to facilitate downstream treatment. The demineralization unit may convert a product of the oxidation unit to generate a mineral stream. In some examples, the process stream may be a spent caustic stream from an industrial operation, such as an ethylene production facility or a petroleum refinery. A fresh caustic stream, such as a sodium hydroxide stream, may be isolated in the demineralization step and returned to the industrial operation for use.

Abstract: An electrochemical treating device having low scale potential is disclosed. The device has a variety of configurations directed to the layering of the anionic exchange and cationic exchange. The treatment device can also comprise unevenly sized ion exchange resin beads and/or have at least one compartment that provides a dominating resistance that results in a uniform current distribution throughout the apparatus.

Abstract: Electrochemical devices and methods for acid and base generation are disclosed. A source of purified water is fluidly connected to at least one compartment of the device. A source of an ionic species, such as an acid or base precursor, is also provided to at least one compartment of the device. An applied electrical field promotes ion transport across selective membranes which at least partially define the compartments. The purified water may be dissociated into hydronium and hydroxyl ions in an electrolyzing compartment of the device. Acid and/or base product streams may be recovered as desired at outlets of the various compartments. In some embodiments, a bipolar membrane may be used to split water in place of the electrolyzing compartment.

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.
