    Abstract: A device/apparatus for using a multilayer fabric of varying deniers for the processing and treatment of fluids which must be treated to remove materials so that the resultant treated fluid may be reused and/or returned to the earth and particularly to the water table. More particularly the multilayer fabric, each layer being of selected denier, is used in combination with conduit in a drainage field or leaching system usually associated with a septic tank or septic system. Most particularly the multilayer fabric of varying deniers is wrapped around corrugated plastic pipe of the type well known in the field of drainage or leaching fields. At least one of the multilayer fabric layers is formed from an unstructured assemblage of fibers. The unstructured assemblage of fibers are supported by an outer sheeting. Oils, greases and chemicals contained in the fluids to be treated and entering within the fluid conducting conduit structure are entrapped within at least one of the first layers and at least one additional layer of fabric and particularly on the unstructured assemblage of fibers. The unstructured assemblage of fibers provides a large surface area whereon consequent biodegradation of said oils, greases and chemicals takes place permitting treated fluid to pass omnidirectionally through the unstructured assemblage of fibers and subsequently leach into the ground. The particular objectives, features and advantages of the device are: 1) Multiple layers of fabric; 2) Fabric layers of varying deniers; 3) Useful in wrapping corrugated plastic pipe; 4) With the selection of fabric and fabric denier, specific fluid treatment objective can be met; 5) The multilayer fabric provides boundaries/interfaces and regions within which specifically chosen bacteria, chemicals, microbes and the like may be introduced to facilitate the biodegradation of specifically chosen undesirable materials; and 6) Improve performance over the currently known leach fields.

    Abstract: A method and apparatus for testing the integrity of filter elements is provided. The filter assembly comprises a plurality of filter elements which are subdivided into a plurality of sections. By measuring the gas flow rate under known pressure conditions through all of the sections or a selected portion of the sections, defective filter elements can be isolated in a systematic manner.

    Abstract: A filtration system is provided that directs a fluid to be filtered through a disposable tubular filtration element, supports the filtration element, and accommodates for "wet growth" of the filtration element. The system operates with an inside-to-outside forced fluid flow through the filtration element and includes a generally cylindrical housing with a fluid inlet and outlet. A perforated outer support screen is mounted within the housing and surrounds the walls of the tubular filtration element with slight clearance. Under the influence of the fluid pressure and the wet growth, the walls of the filtration element bear against the screen. A sealing and support assembly having upstream and downstream fluid guides, each carrying, in a preferred form, a pair of resilient sealing members, is positioned inside the filtration element. A rigid inner member bridges the opposing faces of the resilient member pairs. A rod and nut arrangement draws the flow guides towards one another to apply a longitudinal compressive force on the resilient members caught between a flange on the flow guides and the rigid inner member. This compressive force deforms the resilient members in a radially outward direction to seal the filtration element to the housing and isolate the filtered fluid. In a preferred form, the adjacent faces of each pair of resilient members are aligned with the interior edge of an impregnated end portion of the filtration element. In addition, a tubular prefiltration element may be positioned inside the rigid inner member.

    Abstract: 919,470. Filters. BERLINE J. R. A. July 25, 1961 [July 27, 1960], No. 26925/61. Class 46. In a cluster of filtering tubes each tube 1 has a flared upper end supported by an annular rubber or plastic gasket 18 in a supporting plate 16 and is held under adjustable pressure from bolts 21 in washers 20 which, through tube retaining rings 19, exert pressure against a plurality of tubes simultaneously. Each tube consists of a core 2 of perforated sheet metal or expanded metal and a sheath 5 of metal or synethetic fabric e.g. " Terylene " Registered Trade Mark and is rigidly united with an endpiece 4 which is secured to a metal lattice 6 by a stud 8. For cleaning, filtrate accumulated in a dome of the filter housing is counterstreamed by the pressure of gas in the dome, or introduced thereto, and this with the help of the resultant vibration of the tubes, causes the filter cake on the outer face of the filter fabric to be removed. Alternatively, steam under pressure may be used to clean the tubes. The washers may be circular or star-shaped, each point of a star being assigned to a tube.
