Abstract:
There can be obtained an ecological filtration apparatus providing a sufficient function of precise filtration while contributing to saving resources and minimizing refuse. The filtration apparatus includes a housing having an inlet and an outlet, an outer cylinder fixed to the housing, and a cartridge filter formed mainly of a cylindrical filter, an inner cylinder and end caps. The cartridge filter is detachably attached to the housing, housed in the outer cylinder, blocking a channel extending from the inlet to the outlet.
Abstract:
A method for producing a filter element made wholly of a fluorocarbon resin, comprises forming a sheet of filter membrane made of a fluorocarbon resin and net supporters made of thermoplastic fluorocarbon resin superimposed on both surfaces of the resin, into a pleat form. The pleated sheet is bent into a cylindrical form. The edge parts of the adjacent sides are liq. tightly welded pref. using a tape. The pleats are pre-welded by heating both end parts of the cylindrical pleat filter to a temp. higher than the melting pt. of the net supporter. The filter is cooled. A thermoplastic fluorocarbon resin is melted and forced into the end parts of the pleats in a mould integrally welding the end parts in the resin.
Abstract:
Aground water flow device (1) has a support element (3) and a filter sheet (5). The filter sheet has a first side (7) and a second side (9). Tubes (13) are provided with flow apertures (11) which are large enough to allow the passage of water and soil particles. The tubes (13) each have an inner space (17). The tubes (13) each hold one of the filter sheets (5) in their inner space (17).A first part of the flow apertures (11) is facing the first side (7) of the filter sheets (5) and a second part of the flow apertures (1) is facing the second side (9) of the filter sheets (5), defining in each tube (13) a flow path (19) for ground water from the first part of the flow apertures (11) through the filter sheet (5) to the second part of the flow apertures (11).
Abstract:
Ein Filterelement zur Filtration von Fluiden, mit einer flächigen Stützstruktur, die die Wand eines Stützrohres (1) bildet, das die Außenseite eines Filtermediums umgibt und eine Durchströmfläche und eine Markierungsfläche (9) bildet, wobei die Durchströmfläche ein Lochmuster (3) bildende Durchströmöffnungen (5) und die Markierungsfläche (9) visuell erkennbare Markierungselemente (11) aufweist, ist dadurch gekennzeichnet, dass die Markierungselemente (11) in der Markierungsfläche (9) durch ein sich vom Lochmuster (3) der Durchströmfläche visuell erkennbar abhebendes zweites Lochmuster (13) gebildet sind.
Abstract:
Es wird ein Filterelement zur Entfernung von Partikeln aus einem Fluidstrom, insbesondere von Partikeln aus einem Kraftstoffstrom einer Brennkraftmaschine, vorgestellt, bei dem in Durchströmungsrichtung eine Vorfilterlage und eine Feinfilterlage aneinandergefügt sind und wobei auf der Rohseite der Vorfilterlage eine erste Stützlage und auf der Reinseite der Feinfilterlage eine zweite Stützlage zur Aufnahme der Längs- bzw. Querkräfte bei Zugbeanspruchung aufgebracht ist. Die beiden Stützlagen weisen jeweils unterschiedliche durchschnittliche maximale Zugkräfte in Längs- bzw. Querrichtung auf.
Abstract:
A membrane filter element is provided comprising a laminate of an upstream filter and a downstream filter having a separator layer interposed therebetween.
Abstract:
A filter element (12) is disclosed that includes a filtration media (18), an upstream pleat support (16) and a multi-layer downstream pleat support. The multi-layer downstream support includes a first downstream support layer (19) and a second downstream support layer (22). The first downstream support layer is in contact with the filtration media and is interposed between the filtration media and the second downstream layer. The first downstream support layer is fabricated so as to minimize points of surface contact with the filtration media, thereby enhancing fluid flow away from the filtration media. The second downstream support layer is in contact with the first downstream support layer and is fabricated so as to facilitate lateral fluid flow relative to the multi-layer downstream pleat support. The disclosed filter element may be utilized in filter cartridges of various designs to provide enhanced filtration performance, e.g., by way of increased media area and improved flow/throughput.
Abstract:
A filter is disclosed that includes a cylindrical filter element having a longitudinal axis, an outer periphery, an inner periphery, and a plurality of longitudinal pleats arranged in a spiral configuration in close proximity to one another. Each of the pleats has a pair of legs, and the legs of each are joined to one another at a root. The roots of adjacent pleats are radially spaced from one another about the inner periphery of the filter element.
Abstract:
A fluid treatment element for treating a fluid flowing through the pack comprises a first conductive layer and a second conductive layer electrically connected to the first conductive layer. The element further comprises a nonconductive porous treatment medium between the first and second conductive layers. The first and second conductive layers are positioned to offset electrical imbalances caused by fluid flowing through the nonconductive porous treatment medium. A fluid treatment pack for treating fluid flowing through the pack comprises a porous treatment medium and an electrical cage. The electrical cage surrounds the porous treatment medium and offsets electrical imbalances caused by fluid flowing through the porous fluid treatment medium.
Abstract:
A filter canister is disclosed that includes a main body having a top. An inlet port is positioned on the top of the main body and an outlet port also positioned on the top of the main body, offset from the inlet port by a predetermined distance. A filter cartridge is positioned within the main body that has an outlet end that sealingly engages the outlet port. An inlet port identifier is associated with the inlet port, and an outlet port identifier is associated with the outlet port. A valve is also disclosed that operates in connection with the filter canister.
