Abstract: Anion exchange membranes and materials including silica-based ceramics, and associated methods, are provided. In some aspects, anion exchange membranes that include a silica-based ceramic that forms a coating on and/or within a porous support membrane are described. The anion exchange membranes and materials may have certain structural or chemical attributes (e.g., pore size/distribution, chemical functionalization) that, alone or in combination, can result in advantageous performance characteristics in any of a variety of applications for which selective transport of positively charged ions through membranes/materials is desired. In some embodiments, the silica-based ceramic contains relatively small pores (e.g., substantially spherical nanopores) that may contribute to some such advantageous properties. In some embodiments, the anion exchange membrane or material includes quaternary ammonium groups covalently bound to the silica-based ceramic.

Abstract: Disclosed are a method and system for resource treatment of a reverse osmosis concentrated brine (ROC) by bipolar membrane electrodialysis. The method includes: adding a calcium-magnesium precipitant to ROC, and mixing, to remove hardness; filtering a resulting mixture through diatomaceous earth, to intercept an organic matter and a precipitate; adjusting a resulting filtrate to be acidic with a pH adjuster; feeding a resulting acidic filtrate in an electro-Fenton reaction device, and subjecting the resulting acidic filtrate to oxidation under an acidic environment, such that a chemical oxygen demand removal rate is not less than 97%; subjecting a resulting effluent from the electro-Fenton reaction device to fine filtration with a polypropylene microporous filter, to obtain a fine filtrate; and introducing the fine filtrate into a bipolar membrane electrodialysis device, and performing the bipolar membrane electrodialysis, to generate an acid and an alkali under the action of an external electric field.

Abstract: Systems and methods utilize semipermeable nanotubes in conjunction with application of controlled electrical potentials across semipermeable nanotube walls allow selective transport of charged impurities (e.g., charged impurities, ions, etc.) from a fluid into these nanotubes. Impurities collected in these nanotubes can then be removed from the fluid, (e.g., blood) as a waste stream. A collection of semipermeable nanotubes each carrying a waste stream can be aggregated and merged into a ureter for excretion thereby providing an artificial kidney system. Sensors that detect/measure various impurities may be included in the system to feed information to a microprocessor to inform on concentrations of impurities, and thereby control electrical potentials applied to the system.

Abstract: Air flows across an air-liquid interface such that liquid desiccant flowing through the interface absorbs water from the air and is thereby diluted to form an output stream. The output stream is circulated through an electrodialytic stack having a central ionic exchange membrane and first and second outer ionic exchange membranes. A redox shuttle loop circulates around the first and second outer ionic exchange membranes. A voltage is applied across the electrodialytic stack, which regenerates the liquid desiccant.
