摘要： The invention relates to a membrane assembly and processes for the utilization of the membrane assembly, or membrane assemblies having like properties. The membrane assembly comprises intermixed layers of capillary material and high dielectric constant impermeable material, forming capillary channels parallel to the direction of ion transport through the membrane. The membrane is anion permeable, does not have membrane potential and will not foul even over extended operation, allows cross-flow of anions and cations, and is highly efficient. It is possible to remove complex metals from any contaminated acid by electrodialysis, such as removing vanadium and uranium in recoverable form from contaminated phosphoric acid, while producing food grade phosphoric acid in the process. Additionally, simple metals may be removed from mine waste liquids (from leaching), chlorine can be produced from a chloride containing salt, and chromium can be removed from chromium contaminated water by electrolysis. Milling sludge can be treated to form water, caustic, and acid, and mineralized water can be treated to form de-mineralized water, by subjecting the feed liquids to electrodialysis.
摘要翻译：本发明涉及膜组件和利用膜组件的方法，或具有相似性质的膜组件。膜组件包括毛细管材料和高介电常数不渗透材料的混合层，形成平行于通过膜的离子传输方向的毛细管通道。膜是阴离子可渗透的，不具有膜电位，即使在延长的操作中也不会弄脏，允许阴离子和阳离子的交叉流动，并且是高效的。可以通过电渗析从任何污染的酸中除去复杂的金属，例如从污染的磷酸中除去可回收的钒和铀，同时在该过程中生产食品级磷酸。另外，简单的金属可以从矿石废液中除去（浸出），可以由含氯化物的盐生成氯，并且可以通过电解从铬污染的水中除去铬。研磨泥浆可以处理形成水，苛性碱和酸，并且可以通过对进料液进行电渗析来处理矿化水以形成去矿化水。

摘要： Composite structures composed of inorganic membranes or polymer membranes supported on a multilayered woven wire mesh substrate are provided. Also provided are methods of making the composite structures and methods of using the composite structures as separation membranes. The mesh substrates are composed of a stack of two or more layers of woven wire mesh, wherein the different mesh layers in the stack have different mesh sizes. The multilayered mesh structure can support a defect-free, or substantially defect-free, membrane and has sufficient mechanical strength to allow the supported membranes to be used for chemical separations.

摘要： Various embodiments of a system and method for enriching a concentration of components of interest in an air flow are described. The system includes an apparatus for enriching a concentration of components of interest in an air flow. The apparatus includes a chamber and a tube having a tube wall made of a selectively permeable material positioned within the chamber. A first end of the tube is connected to the inlet port of the chamber and a second end of the tube is connected to the outlet port of the chamber. The selectively permeable material has a lower permeability to components of interest than to inert gases, and the selectively permeable material is non-reactive with components of interest. The apparatus is configured to receive a sample stream and the chamber is maintained at a chamber pressure that is different than a stream pressure of the sample stream.
