Abstract: This invention presents an ion exchange media including a plurality of cation exchange zones and anion exchange zones in flow paths that are contained in a substantially nonporous resin transport framework. During electrodeionization and other potential applications the ion exchange media of the invention prevents unfavorable water splitting at resin-membrane interfaces and encourages water splitting at resin—resin interfaces where the water splitting may be constructively used to regenerate the resin.

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: A liquid treatment process is described for sequential removal of ionic species of progressively decreasing ionic strength without precipitation or “scaling.” An embodiment of the invention includes dual electrodeionization operations. The first electrodeionization operation is performed at a voltage calculated to remove strongly ionized species such as calcium and magnesium from the feed water without scaling. The product of the first electrodeionization operation is then subjected to a second electrodeionization operation. The second electrodeionization operation is performed at a voltage greater than the first electrodeionization operation, and is designed to remove more weakly ionized species such as silica and atmospheric carbon dioxide. The danger of precipitation or “scaling” normally present during electrodeionization of weakly ionized species is not present in this invention, because the strongly ionized species responsible for scaling at higher voltages have already been removed from the feed stream through the first electrodeionization operation. More than two successive electrodeionization operations may be performed if desired. Multiple electrodeionization operations may occur in a single electrodeionization stack or in multiple electrodeionization stacks.

Abstract translation: 描述了一种液体处理方法，用于顺序地去除逐渐降低的离子强度的离子物质，而没有沉淀或“结垢”。 本发明的一个实施方案包括双电解离子化操作。 第一电去电离操作以计算为从进料水中除去强烈离子化物质例如钙和镁的电压进行，而没有结垢。 然后对第一电去电离操作的产物进行第二电去离子化操作。 第二电去离子化操作以大于第一电去离子化操作的电压进行，并被设计成去除更弱的电离物质，例如二氧化硅和大气二氧化碳。 由于在较高电压下负责结垢的强电离物质已经通过第一电去离子操作从进料流中除去，所以在弱电离物质的电去离子中通常存在的沉淀或“结垢”的危险通常不存在。 如果需要，可以进行两次以上的电去离子化操作。 多个电去离子化操作可能发生在单个电去离子堆叠或多个电去离子堆叠中。

A single first cation exchange membrane 3, a single anion exchange membrane 4, a single second cation exchange membrane 3′ are arranged between a cathode 1 and an anode 2 so that a concentration-cathode compartment 5, a desalting compartment 7, a concentrating compartment 10, and an anode compartment 6 are formed, in this order, between the cathode 1 and the anode 2. The concentration-cathode compartment 5 and the anode compartment 6 are filled with a cation exchange resin 8, respectively. The desalting compartment 7 is filled with a mixture of the cation exchange resin 8 and an anion exchange resin 9. Fed into the anode compartment 6 is raw water or deionized water. Water from the anode compartment is sent to the concentrating compartment 10 and the concentration-cathode compartment 5 sequentially.
