A filter is provided comprising a filter media element enclosed by an impermeable bag with inlet and outlet ports provided for flow into and out of the bag and through the filter media element contained in the bag. The bag may be constructed of a sheet of plastic material of multiple layers. The filter element may be a stack of filter media disks for depth filtration and adsorption. The filter provides for cleanly change out, with unfiltered fluid being contained in the bag on the upstream side of the filter element within the bag.

A filter insert (10) comprising: a body portion (12) and a closed-ended tube (14), an open end of which is sealingly affixed around the periphery of the body portion (12); an inlet aperture (16) and an outlet aperture (18) each aperture communicating via a through hole in the body portion (12) with the interior of the tube (14); a filter medium (20) located within the tube (14) and being sealingly interposed between the inlet aperture (16) and the outlet aperture (18), wherein the tube (14) is at least partially manufactured of a flexible plastics material, and wherein the body portion (12) is relatively rigid.

A filter assembly is provided. The filter assembly includes a filter cartridge with a containment bag including a vent port and a support housing, including a split lid.

A filter assembly is provided. The filter assembly includes a filter cartridge with a containment bag including a vent port and a support housing, including a split lid.

A filtration system including a housing defining an internal volume. The housing includes a housing first end, a housing second end, and a first coupling member formed in the housing. The housing first end is an open end. The housing second end is a closed end. A filter element is positioned within the internal volume of the housing. The filter element is configured to engage the first coupling member. A filter head is provided. A seal member is disposed between the housing first end and the housing second end. The seal member provides a radial seal directly between the housing and the filter head.

A water quality purification assembly includes a housing assembly, a filter element, an inner housing, and a support member. An accommodation cavity is constructed inside the housing assembly; the filter element is disposed in the accommodation cavity; the inner housing is disposed between the housing assembly and the filter element, and a first flow channel is constructed between the inner housing and the housing assembly; a second flow channel is constructed between the inner housing and the filter element. The support member supports the filter element, a water storage cavity is constructed between the support member and a bottom wall of the housing assembly, and the water storage cavity is separately communicated with the first flow channel and the second flow channel.

The invention relates to a filter system for removing and/or neutralizing undissolved oils, greases and salts, preferably also floating bodies, such as metal debris, on/in water-containing emulsions from, in particular, containers and tanks that are used for holding and storing emulsions.

Described herein are examples of protective insulative enclosures which include a housing, comprising a sleeve, and a strap. The sleeve may be configured to envelop a filter, enclosing the filter. The sleeve comprises an insulated material. The strap may be coupled to the sleeve and is configured to prevent inadvertent dislodgment of the sleeve from the filter. The strap may be further configured to securely fasten the protective insulative enclosure to a vehicle body by attaching it to a specific part of the vehicle body.

A slurry filtering device for a rechargeable battery is provided for removing foreign metal substances contained in a slurry for manufacturing an electrode plate for a battery. The slurry filtering device includes a slurry pipe in which a slurry flow path along which the slurry moves is formed and a collection space where foreign metal substances are collected on an interior wall; a first magnetic filtering unit installed at a position on one side of the collection space of the slurry pipe and filtering foreign metal substances contained in the slurry moving in a direction of the collection space; a second magnetic filtering unit installed on the slurry pipe at the collection space position and collecting foreign metal substances filtered in the first magnetic filtering unit into the collection space by magnetic force; and a sensor unit that checks the amount of foreign metal substances collected in the collection space.

A diffusive air purifier includes an air permeable container containing a chemical sorbent or a sorbent precursor. The sorbent has a chemical composition selected to achieve removal of an air pollutant via a chemical reaction that renders the predetermined air pollutant immobile. A method of manufacturing the diffusive air purifier includes impregnating a porous solid with a solution of sorbent precursor and a binding agent and drying the porous solid. A method of purifying indoor air includes detecting a measured concentration of an airborne chemical in an enclosed location; selecting the diffusive air purifier to adsorb the airborne chemical; and placing the diffusive air purifier in the enclosed location. Air diffuses through the outer container and into the sorbent where the chemical to be removed is retained. Air, free of the target chemical, diffuses out of the container and the process repeats.
