Abstract: A filter medium is provided with a layer (A) provided with non-impregnated active carbon, a layer (B) with a solid carrier material that is impregnated with a permanganate salt, and a layer (C) with alkaline impregnated active carbon. The layer (B) and the layer (C) are arranged such that a gas flowing through the filter medium flows through the layer (B) before flowing through the layer (C). The layer (A) is arranged such that the gas flowing through the filter medium flows through the layer (A) before flowing through the layer (B) or the gas flowing through the filter medium flows through the layer (A) after flowing through the layer (C).

Abstract: A detoxification device for removing pathogens from air within an environment. The detoxification device may include a filtration media for catching and retaining particles larger than about 0.3 micrometers (μm) with an efficiency of at least 99%. The detoxification device may also include a heating element having a metallic foam. The heating element may be heated upon application of an electrical current to the heating element. The heating element may, upon being heated, heat the filtration media to a target temperature that is effective to kill a pathogen.

Abstract: A fluid control device includes a support structure configured to be deployed in a borehole, and a filtration component disposed at the support structure, the filtration component including a porous medium made from a thermoplastic polymer material, the porous medium including an open cell foam. The porous medium has a porosity selected to cause the porous medium to exhibit shape memory behavior, and the porous medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded due to a downhole temperature to conform to a surface of the borehole.

Abstract: A polypropylene resin composition which may prevent deterioration of properties due to moisture. The polypropylene resin composition has low surface energy, and thus may increase chemical stability against external factors. Further, a molded product including the polypropylene resin composition may have low ion elution ability, which may be an important requirement, and may achieve high weight reduction.

Abstract: Articles and methods involving filter media are generally provided. In certain embodiments, the filter media includes at least a first layer, a second layer, and an adhesive resin positioned between the first layer and the second layer. In some embodiments, the first layer may be a pre-filter layer or a support layer. The second layer may, for example, comprise fibers formed by a solution spinning process and/or may comprise fine fibers. In some embodiments, the adhesive resin may be present in a relatively low amount and/or may have a low glass transition temperature. The filter media as a whole may have one or more advantageous properties, including one or more of a high stiffness, a high bond strength between the first layer and the second layer, a high gamma, and/or a low increase in air resistance after being subjected to an IPA vapor discharge. The filter media may be, for example, a HEPA filter and/or an ULPA filter.

Abstract: A polishing filter employed within a sump pump system for removing mineral oils, natural ester, and synthetic ester-based fluids from an emulsion is provided. The polishing filter is disposed within a sump pump barrier and is gravity-fed a synthetic ester and water based emulsion via a polishing filter conduit. The polishing filter removes excess synthetic ester-based fluids from a water/oil emulsion fluid flowing through a barrier canister disposed within the sump pump barrier above the polishing filter and releases a resultant filtered fluid. The polishing filter cartridge contains a filtration media with a hydrophilic composition for the capture of synthetic ester-based fluid having a surface tension dissimilar to water, and the hydrophilic composition of the media has a surface energy greater than or equal to 35 dynes per centimeter.
