Abstract: A layered separation media includes a fibrous layer including a non-woven media; and a first coating disposed on the non-woven media, the first coating comprising a crosslinked hydrogel; and a membrane layer including a membrane; and a second coating disposed on the membrane. The second coating may also include a crosslinked hydrogel. The layered separation media may be used in a system for membrane chromatography. A method of separating a protein from a liquid stream may include flowing the liquid stream through the layered separation media. The protein may bind with functional groups in the hydrogel. The layered separation media may have a DBC10 of 50 mg/mL or greater.

Abstract: The current technology relates to filter media configurations where the filter media has a surface with a treatment that increases the roll off angle of the surface for a 50 μL water droplet when the surface is immersed in toluene. Some example filter media have a fluted configuration, and some example filter media have multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.

Abstract: A system for separating a solvent includes a first mixing tank comprising a waste solvent feed and a reactant feed; a first filter comprising a nanofiltration membrane; a distillation column or an evaporator; a condenser or cooler; and a pervaporation membrane. A method for separating a solvent includes mixing a waste solvent with a reactant to cause precipitation or complexing and forming a mixture; filtering the mixture using a nanofiltration membrane and forming a permeate; distilling or evaporating the permeate to form a concentrated solvent; condensing or cooling the concentrated solvent to below a boiling point of solvents in the concentrated solvent; and filtering the concentrated solvent using pervaporation to form a purified solvent. The system and method may be used to separate and purify a solvent without creating thermal degradation products.

Abstract: A system for producing steam includes a source of superheated water with superheated water output; a membrane filtration system in fluid communication with the superheated water output and including a membrane filter with a permeate side and an opposing retentate side. The membrane filter includes a separation membrane constructed to reject organic molecules. The system may be used for removing organic compounds, such as anti-corrosion agents or contaminants, from superheated water to produce steam. A method for producing steam includes directing a cross-flow of heated pressurized water including a first concentration of an organic compound across a membrane filter. The membrane filter includes a separation membrane constructed to reject the organic compound; and one or more support layers adjacent the separation membrane. A steam permeate including a second concentration of the organic compound is collected, where the second concentration is lower than the first.

Abstract: A deaerator includes gas nucleation media and a porous barrier. The deaerator may include growth media between the gas nucleation media and the porous barrier. The deaerator may be part of a system for removing gas from a fluid, where the system includes a tank with a fluid inlet and a fluid outlet and having a fluid flow path from the fluid inlet to the fluid outlet, and where the deaerator is in the fluid flow path. A method for removing gas from a fluid includes passing the fluid through the deaerator defining a fluid flow path.

Abstract: The current technology relates to various filter elements configurations where a substrate layer defines a surface having a treatment. The treatment increases a roll off angle of the surface for a 50 water droplet when the surface is immersed in toluene. The filter element can have a housing and the substrate disposed in the housing. In some embodiments the substrate layer defines a plurality of pleats extending between pleat folds that form flow faces of the media. In some embodiments the substrate is incorporated into single facer media of a filter element. In some embodiments the substrate layer is incorporated in a filter element having a flow-by configuration. In some embodiments the substrate layer is incorporated in a filter element having a cross-flow configuration. Some embodiments relate to a vent. Some embodiments relate to a barrier assembly and/or a fuel filter element. Various other filter elements are described.
