Abstract: A thermally bonded filtration media that can be used in high temperature conditions in the absence of any loss of fiber through thermal effects or mechanical impact on the fiber components is disclosed. The filter media can be manufactured and used in a filter unit or structure, can be placed in a stream of removable fluid, and can remove a particulate load from the mobile stream at an increased temperature range. The combination of bi-component fiber, other filter media fiber, and other filtration additives provides an improved filtration media having unique properties in high temperature, high performance applications.

Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which a filter cartridge having a media pack and a seal arrangement surrounding the media pack can be installed. The air cleaner assembly may also include a projection-receiver arrangement in which the filter cartridge has at least one first member and the housing has at least one second member that interacts with the first member. In one example, a portion of the seal arrangement is coplanar with the first member and a portion that is below the first member such that the first member is located between the seal arrangement and an inlet end of the filter cartridge.

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 filter assembly for an enclosure, particularly for an ostomy bag, is described having an enclosure side, a first layer which is gas permeable, and an adsorbent layer comprising adsorbent particles dispersed in a fine fiber web. The enclosure side of the filter assembly includes an adhesive zone in which adhesive is present having an outer adhesive perimeter and a weld area surrounding at least a portion of the adhesive zone, where the filter assembly is heat-sealable to the enclosure at the weld area. A method of assembly is also described.
