A composite adsorbent for adsorbing water includes a silica-cage having plural pores and internal channels that fluidly connect the plural pores, at least one interior chamber having an average diameter larger than an average diameter of the plural pores, wherein the at least one interior chamber is a result of a collapse of at least one pore of the plural pores and one channel of the internal channels, and a salt provided within the plural pores, the internal channels and the at least one interior chamber.

A device for treating a gas laden with pollutants, includes at least one adsorption module for adsorbing the pollutants, which is utilized in an adsorption apparatus. The adsorption module includes at least one electrically conductive layer of an activated carbon fiber mat, an electric current circuit for heating the activated carbon fiber mat for the desorption of the adsorbed pollutants, and distributing conduit which is routed into the center of the adsorption module and has outlet openings for a flush gas for inertizing and rinsing the activated carbon fiber mat.

Provided herein are methods of reducing bioburden of (e.g., sterilizing) a chromatography resin that include exposing a container including a composition including a chromatography resin and at least one antioxidant agent and/or chelator to a dose of gamma-irradiation sufficient to reduce the bioburden of the container and the chromatography resin, where the at least one antioxidant agent and/or chelator 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 at least one chelator and/or antioxidant agent, 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.

An adsorption apparatus and associated method for capturing a target gaseous adsorbate from an atmospheric air based gaseous feed stream. The adsorption apparatus includes a housing enclosing at least one adsorption element for adsorbing the target gaseous adsorbate, at least one substrate coated with an adsorptive composite coating that comprises at least 50 wt % metal organic framework and at least one binder, the housing having an inlet through which the gaseous feed stream can flow to the adsorption element and an outlet through which gas can flow out from the housing; and a desorption arrangement in contact with and/or surrounding the at least one adsorption element.

A solvent extraction process for removing poly- and perfluoroalkyl substances (PFAS) from a PFAS laden adsorbent is disclosed. The process comprises introducing a substantially pure solvent at an elevated temperature to a bed of the PFAS laden adsorbent and continuously removing PFAS laden solvent from the adsorbent, wherein the introducing and removing are carried out simultaneously and continuously until a desired amount of PFAS is removed from the adsorbent. Also disclosed is a process for degrading poly- and perfluoroalkyl substances (PFAS) to environmentally benign products. The process comprises providing an aqueous solution containing PFAS at a concentration of greater than 50 ppm; and subjecting the aqueous solution to ultrasound using at least one ultrasonic transducer at a frequency and power and for a time sufficient to degrade substantially all of the PFAS in the solution to carbon dioxide and fluoride.
