A liquid filter cartridge is provided. Preferred seal arrangements are provided, to provide for preferred axial load conditions, with respect to one or more of the end caps of the cartridge. Some cartridge configurations provided include no core structure or outer liner structure therein, to support axial load. Assemblies using the cartridge, and methods of assembly and use, are provided. The liquid filter cartridge can be a serviceable cartridge, or it can be retained permanently in a housing.

A method is provided for supporting environmental control in a semiconductor wafer processing space, the method includes: flowing a first gas under pressure in a first direction through a first diffuser tube, thereby generating a first lateral flow of gas through a sidewall of the first diffuser tube; flowing a second gas under pressure in a second direction through a second diffuser tube, thereby generating a second lateral flow of gas through a sidewall of the second diffuser tube, the second direction being opposite the first direction; combining the first and second lateral flows of gas within a housing; and outputting the combined lateral flows of gas from the housing to produce a laminar gas flow covering an opening to the semiconductor wafer processing space.

A water treatment method used in a water treatment device including a filter for filtering untreated water and a housing that houses the filter includes a step of putting the untreated water into the housing to obtain filtered water that has permeated through the filter, and a step of replacing the untreated water in the housing by storage water. The storage water is water having less favorable survival conditions for microbes than the untreated water.

Improvements to a liquid permeable barrier or filter for a basket, basin, or sink. An expandable filter for a basket, basin, or sink, the filter including a filter material shaped and formed to having a peripheral region, a plurality of panels, and a central collection region, the peripheral region having an upper surface and a lower surface, and the plurality of panels extending from the central collection region towards the peripheral region; and one or more folds in the filter, each of the one or more folds permitting each of the plurality of panels to overlap an adjacent portion of the filter, wherein the filter can be unfolded from a folded orientation to a partially unfolded orientation.

An in tank depth media fuel filter assembly includes a closed body having an interior and an exterior. The closed body has a first composite panel of filtration media and a second composite panel of filtration media. Each of the composite panels includes and outer support layer and at least three inner layers of filtration material including at least two spunbonded layers of synthetic filaments and at least one layer of wetlaid synthetic fibers. An opening is provided in the body for providing fluid communication with the interior thereof.

A multi-layered, web-shaped filter material for a filter element may include a fleece layer, a cellulose layer, and a nanofiber layer arranged between the fleece layer and the cellulose layer. The nanofiber layer may be a coating of a nanofiber material disposed on the fleece layer. The cellulose layer may have an impregnation at least on a side facing the nanofiber layer.

A filter device may include a plurality of sections including one or more panels formed from one or more air filter media and one or more hinges arranged between two or more sections of the plurality of sections. The filter device may be disposed within a space and may be retrieved from the space via a direct access opening within a cooling system. When the filter device is disposed within the space, the filter device may be arranged parallel to a coil. When the filter device is retrieved from the space, a first section of the filter device may bend via a first hinge of the one or more hinges to retrieve the first section from the space via the direct access opening of the cooling system.

The disclosure provides a filter layer structure, a filter assembly, and a method of forming a filter layer structure. The filter layer structure has an unwound state. In the unwound state, the filter layer structure includes: a supporting layer; a first hydrophilic protective layer arranged on the supporting layer, where a first end of the first hydrophilic protective layer corresponds to a first end of the supporting layer; and a filter medium layer arranged on the supporting layer, where the filter medium layer extends along a length direction of the first hydrophilic protective layer, a first end of the filter medium layer faces a second end of the first hydrophilic protective layer, and a second end of the filter medium layer corresponds to a second end of the supporting layer.

Articles and methods related to multilayered media are generally provided. Some embodiments are generally related to filter media. Some embodiments relate to multilayered media comprising an irregular structure. The irregular structure may be present on an external surface of the multilayered media, in the interior of the multilayered media, and/or throughout the multilayered media. Some aspects are generally related to multilayered media that are reversibly stretchable and/or comprising a polymeric film.
