摘要： Acid block anionic selective polymeric membranes are provided of the type having a woven or non- woven cloth reinforcing structure. The polymer of the membrane is prepared by the process comprising copolymerizing components I, II, and III wherein I is an ethylenically unsaturated aliphatic or aromatic tertiary or quaternary amine monomer. II is a cross-linking monomer, and III is vinylbenzyl chloride. The reaction is conducted in the presence of a free radical polymerization initiator. Additionally, anionic exchange membranes of the type used in electrodialysis apparatus are disclosed and comprise a woven or nonwoven cloth that is impregnated with a copolymer comprising the reaction products of components I, II, and III.

摘要： A sheet having anion exchange functionality and a sheet having cation exchange functionality are juxtaposed and joined by current bonding into a unitary bipolar membrane. This may be done without added reactants or bonding agents by placing the two-layer assembly between opposed electrodes in a fluid cell, preferably at pressure, and applying power across the cell to split water in a junction region of the membrane assembly. Preferably the anion exchange sheet is treated with an iron salt solution so as to incorporate or immobilize the metal in the polymer during the current bonding process, and enhance operating characteristics of the bipolar junction. Membrane peel strength is comparable to or greater than that of an underlying sheet of ion exchange material, but the bonding is fully reversible, e.g., by soaking in a concentrated solution. Preferably both sheets include an aromatic backbone or cross-linker component. One membrane may be a self supporting membrane, such as a conventional electrodialysis exchange membrane of 5-50 mil (0.12-1.2 mm) thickness, while the other may also be a commercial membrane of opposite exchange type and of similar strength or thickness, or may be specially manufactured to tailor its performance in the completed membrane. For example, one or both starting sheets may be manufactured with a pore former or may otherwise have its porosity, cross-linking, strength, ion rejection characteristics or thickness tailored for more effective bipolar operation -for example, to enhance transport or diffusion, resist shear or mechanical forces, improve chemical resistance to splitting products or species in the intended feed, or the like. Preferably, prior to contacting and bonding, the anion exchange membrane is treated with a group VIII metal salt. The current-bonded unitary bilayer construction remains contact bonded over its surface and resists degradation in normal use.

摘要： A fluid from a fermentation process or the like is passed or circulated through chambers of a bipolar membrane electrodialysis unit to separate an ionizable organic acid stream and at least one co-ion or residual stream. The organic acid stream is preferably concentrated (e.g., by recirculation, dewatering or both), and a product is recovered from the concentrated stream, for example by crystallization, and other outputs from the electrodialysis unit may be integrated with overall treatment and applied elsewhere in the treatment system. Depleted feed may be returned upstream to enhance yield, condition the medium or form a by-product. Treatment systems of the invention may replace a cation exchange bed and/or various filter arrangements, and recirculation of the feed and product flows through the unit enhance recovery, separation and quality of the target species. An ED chamber may include a filling of ion exchange beads to maintain a desired operating efficiency as the feed is depleted, and the straightthrough operation effectively operates as pre-filtration stage to provide downstream product-bearing flows with processing characteristics for enhanced treatment, recovery and product quality. When operated to treat a downstream waste, systems allow additional recovery of value in the form of product, unexpended nutrients, co-factors and/or other components present in the waste.
