Abstract: A back-flushable filter cartridge includes a cylindrical exterior fluid-permeable filter media cage, a cylindrical interior fluid-permeable core element coaxially disposed within the filter media cage so as to establish therebetween an interior space, and longitudinally pleated filter media surrounding the core element and disposed in the interior space such that individual pleats thereof extend substantially radially outwardly from the core element. An annular space is established between outer longitudinal folds of the pleated filter media and the filter media cage. The pleated filter media is radially expandable into the established annular space to allow individual adjacent pleats of the pleated filter media to circumferentially separate from one another in response to fluid flowing in a radial direction from the core element toward the filter media cage.

Abstract: A pleated, all poly(tetra-fluoro ethylene) filter element (20) incorporating a poly(tetra-fluoro ethylene) filter membrane (24) is shown and described. The membrane is supported by an all poly(tetra-fluoro ethylene) paper (26) and (28), which permits filtrate to pass through the paper and across the poly(tetrafluoro ethylene) membrane. A sandwich is formed by placing a layer of poly(tetra-fluoro ethylene) filter membrane (24) between the two layers of poly(tetra-fluoro ethylene) support paper, (26) and (28), and the sandwich is then pleated prior to assembly around a core (14) and between end caps (12) and (18), which are bonded to the poly(tetra-fluoro ethylene) paper and poly(tetrafluoro ethylene) filter membrane by a hot-melt process.

Abstract: The present invention relates to a filter including a filter element having a sucession of inner connected pleats. The pleats have successive pleat tips which define an outer boundary of the filter element. Covering the entire outer boundary of the filter element is a permeable generally inelastic sheet which extends across successive pleat tips. The sheet is adhesively affixed to the pleat tips for maintaining spacing of the pleats. The sheet comprises of plurality of randomly arranged plastic filaments which are bonded to each other junctions between the filaments and define a plurality of randomly spaced and shaped opening for allowing substantially unrestricted flow of a fluid through the sheet.

Abstract: An air drying cartridge for use in an air drying system is disclosed. The air drying cartridge comprises a telescoping casing resiliently self adjustable in height which has an inner cylindrical apertured wall and an outer cylindrical apertured wall. The inner apertured wall has a facing surface, an upper end and a lower end. The outer apertured wall has a facing surface, an upper end and a lower end. The facing surface of the inner apertured wall is disposed to face the facing surface of the outer apertured wall thereby defining an opening therebetween. The air drying cartridge also includes a porous filter liner, a pair of sealing caps and a moisture absorbing material for extracting moisture from air flowing through the air drying cartridge. The porous filter liner is situated adjacent to each of the facing surfaces within the opening. One of the pair of sealing caps affixes to the upper ends of the apertured walls and another affixes to the lower ends of the apertured walls. The moisture absorbing material fills the opening between the filter liners and sealed therein between the sealing caps. The telescoping casing resiliently withstands compressive forces that would collapse, rupture or otherwise distort prior art dryer cartridges. The desiccant cartridge 30 exsiccates air more reliably and efficiently than prior art desiccant devices.

Abstract: An improved electro-coalescent/magnetic separation (ECMS) system for removing contaminants from water, including desalinization, comprises a device for exposing a stream of water to be treated to an electric field, followed by introduction of ionized coagulating substances, including ionized gases and/or metal ions, followed by plural filter stages. The first filter stage may comprise a polarizable glass, alumina, or ceramic media provided as a bed in a tank with an underdrain, so as to provide substantial residence time. A polishing filter may comprise a very fine fiber or organic gel filter element confined between relatively flexible electrically-conductive screen members and provided with a DC power supply to polarize the filter. This assembly is confined between relatively rigid, perforated members such that the filter assembly can move slightly upon backwash to dislodge caked-on contaminants or the like, while preserving the structural integrity of the filter assembly.

Abstract: A porous filter medium is formed by a pleated cylinder of a depth filter medium. An absolute rated inner filtration layer is arranged between upstream and downstream drainage layers. The depth filter medium is formed from a continuous sleeve. Additionally or alternatively at least the downstream drainage layer may be formed integrally with at least a part of an inner filtration layer. The material of the medium may be a fibrous mass of non-woven synthetic polymeric micro-fibres which are free of fibre-to-fibre bonding and are secured to each other by mechanical entanglement or intertwining, with the diameter of the fibrous structure varying across the medium.
