摘要： Disclosed herein are compositions and methods for manufacturing composite paper-based sorbents configured for durability, and high surface area exposure to air. Composite paper-based sorbents can comprise fibers (e.g. natural and/or synthetic fibers), anion exchange resins, and additives. Composite paper-based sorbents can be configured for durability when used in various forming processes, e.g., corrugation, and when used under a variety of conditions, for example, in high and low humidity environments.

摘要： Provided herein are methods of reducing bioburden of a chromatography resin that include exposing a container including a composition including (i) a chromatography resin and (ii) a liquid including at least on alcohol to a dose of gamma-irradiation sufficient to reduce the bioburden of the container and the chromatography resin, where the at least one alcohol are present in an amount sufficient to ameliorate the loss of binding capacity of the chromatography resin after/upon exposure to the dose of gamma-irradiation. Also provided are reduced bioburden chromatography columns including the reduced bioburden chromatography resin, compositions including a chromatography resin and a liquid including at least one alcohol, methods of performing reduced bioburden column chromatography using one of these reduced bioburden chromatography columns, and integrated, closed, and continuous processes for reduced bioburden manufacturing of a purified recombinant protein.

摘要： A system and method for generating water concentrated in calcium bromide from produced water, to provide for drilling fluid having the calcium bromide. The technique includes flowing the produced water through a bed of ion-exchange resin to sorb bromide ions from the produced water onto the ion-exchange resin, and then regenerating the ion-exchange resin to desorb the bromide ions for combination with calcium ions to acquire an aqueous solution with calcium and bromide.

摘要： A sustainable system for removing and concentrating per- and polyfluoroalkyl substances (PFAS) from water. The system includes an anion exchange vessel having a selected anion exchange resin therein configured to remove PFAS from the water. A line coupled to the vessel introduces a flow of water contaminated with PFAS such that the PFAS bind to the selected anion exchange resin and are thereby removed from the water. A regenerant solution line is coupled to the anion exchange vessel to introduce an optimized regenerant solution to the anion exchange vessel to remove the PFAS from the anion exchange resin, thereby regenerating the anion exchange resin and generating a spent regenerate solution comprised of the removed PFAS and the optimized regenerant solution. A separation and recovery subsystem recovers the optimized regenerant solution for reuse and separates and concentrates the removed PFAS.

摘要： The present disclosure is directed to processes for reducing the endotoxin level in gelatin and the resulting gelatin with low endotoxin content. The process includes dissolving a salt in a gelatin solution and filtering the gelatin-salt solution using anion exchange to reduce the endotoxin level. After reducing the endotoxin level of the gelatin-salt solution, the low endotoxin gelatin-salt solution is desalted to remove the salt, thereby producing a low endotoxin gelatin solution.

摘要： An energy efficient and durable thermal swing type carbon dioxide recovery and concentration device can be made smaller and use low-temperature heat waste of 100° C. or less. A honeycomb rotor carries adsorption particles having a sorption capacity for carbon dioxide. The rotor is rotated in a sealed casing divided into at least an sorption zone and a desorption zone and is brought into contact with material gas that contains carbon dioxide in a state wherein the honeycombs in the sorption zone are moist so as to adsorb the carbon dioxide while carrying out evaporative cooling of water. Then, the honeycombs that have adsorbed the carbon dioxide are moved to the desorption zone and brought into contact with low pressure vapor so as to desorb high concentration carbon dioxide. Thus, it is possible to continuously recover carbon dioxide at a high recovery rate and high concentration.

摘要： Disclosed herein is a process for carrying out an ion exchange process which involves providing two interacting sets of banks of continuously stirred tank reactors (CSTR's) each containing a bed of ion exchange resin and causing the resin to move in one direction through each bank of reactors and the feed solution and/or or eluant in the opposite direction. In carrying out the process, a feed solution is introduced in a first reactor causing dissolved ions to be captured on the resin, eluant is introduced into a reactor upstream of the first reactor in the direction of resin movement causing ions captured on the resin to be removed into the eluant and eluant rich in ions removed from the resin will be taken from a reactor upstream of the reactor in which the eluant was introduced, for further processing. Thus, in this form of the invention there is, in effect, a loading bank of reactors in which ions from the feed solution are captured followed by a regenerating bank of reactors in which the eluant removes the ions captured on the resin and regenerates the resin.
