Abstract: Ion transport apparatus (e.g. an electrolytic eluent generator or a suppressor for ion chromatography) in which ions in a first chamber are transported to a liquid in second chamber through a wall comprising an ion exchange bead sealed in a bead seat. The wall is capable of transport ions but of substantially blocking bulk liquid flow.

Abstract: A porous ion exchanger includes an open cell structure including interconnected macropores and mesopores whose average diameter is in a range of 1 to 1000 μm existing on walls of the macropores. Moreover, a total pore volume is in a range of 1 to 50 ml/g, ion exchange groups are uniformly distributed, and an ion exchange capacity is not less than 0.5 mg equivalent/g of dry porous ion exchanger. The porous ion exchanger can be used as an ion exchanger filled into a deionization module of an electrodeionization water purification device, solid acid catalyst, adsorbent, and filler for chromatography.

Abstract: EDI apparatus for demineralizing a liquid flow is assembled in a housing having a cylindrical shape, and includes two metal electrodes, and one or more leafs, each leaf comprising a pair of selectively ion-permeable membranes arranged parallel to each other and spaced apart by spacing elements that allow liquid to flow in the interstitial space between membranes, thus forming an arrangement of dilute and concentrate cells in a desired flow configuration. Spacing elements between membranes, as well as between leaves, can be formed of inert polymer material, ion exchange beads, ion exchange fibers, a combination of two or more these elements, or a porous media incorporating one or more of such elements as an intrinsic part. An inner or central electrode and an outer or perimeter electrode establish a generally uniform and radially-oriented electrical or ionic current between the inner and the outer electrodes, across the helical flow spaces defined by the membrane/spacer windings. One or both electrodes may include a pocket, and the adjacent flow cells lie parallel to the electrode and free of shadowing and field inhomogeneity around a full circumference of the electrode. Flow paths within the helical cells are defined by barrier seals, which may form a path-lengthening maze, while unfilled cell regions may disperse or collect flow within a cell and define pressure gradients promote directional flows. Impermeable barriers between membranes further prevent the feed and concentrate flows from mixing. In various embodiments, seals along or between portions of the flow path may define a multi-stage device, may define separate feed and/or concentrate flows for different stages, and/or may direct the feed and concentrate flows along preferred directions which may be co-current, counter-current or cross-current with respect to each other within the apparatus.

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: The present invention provides a method and apparatus for purifying effluent wastewater utilizing electrophoretic cross-flow filtration and electrode ionization. The method first comprises filtering the water in a cross-flow direction with a filter membrane in the presence of an electric field that is operative to drive suspended particles away from a surface of the filter membrane. The permeate containing dissolved solids is next passed through a mixture of at least one cation-exchange resin and at least one anion-exchange resin disposed between a cation-selective membrane and an anion-selective membrane in the presence of an electric field. The electric field drives cations in the permeate through the cation-selective membrane, and drives anions in the permeate through the anion-selective membrane, thereby to form deionized water. The apparatus includes cell modules adapted to be used in plate-and-frame or radial flow configurations.

Abstract: Apparatus and method are disclosed for introducing ion exchange or other particulates into compartments of an already-assembled electrodeionization or comparable stack by modulating a flow of slurry into the compartments with slugs of gas such as air. The air propels liquid through the cells, scavenging ponded liquid so that the particulates (which are retained, e.g., by a strainer or obstruction, in compartment of the apparatus) are deposited as well-packed beds to fill the compartments. Pressurized air filling protocols may deliver discrete slugs of slurry between bursts of air, and the direction of filling may be periodically reversed to diminish particle bed non-homogeneities or settling gradients that arise during transport. The slugs of air may be applied in the direction of slurry flow, in the reverse direction, or both. Different slurries may be transported in a sequence to form layered and packed beds of enhanced utility. An apparatus of the invention has filled compartments of enhanced packing, and is ported or has its passages arranged so that ion exchange material may be filled, or may be replenished by a fluidized flow according to a method of this invention.
