摘要:
A filter element (16) includes a ring of filtration media (54) circumscribing a central axis, and first and second end caps (60, 62). The first end cap (60) includes i) an annular body portion (66) defining a central opening (68) around the central axis, sealingly bonded to the first end of the media ring (54), ii) an annular sealing ring (80) having an annular, peripheral resilient sealing portion (82); and iii) axial support stanchions (98) around the periphery of the body portion (66). The stanchions (98) support the sealing ring (80) at a location spaced apart from the body portion (66), and define radial flow openings (92) between adjacent stanchions (90). One or more non-radial flow members (94a, 94b) extend from each stanchion (90) along the outer surface (72) of the annular body portion (66) to direct flow in a spiral or helical manner, where the flow then passes through the flow openings (92) and downwardly along the outer surface of the media (54) in a swirling manner.

An improved method and apparatus for filtration includes an outer stationary body (10), an inner rotating body (12) defining a gap with the outer body for receiving a fluid sample (14), the surface of one of the bodies defining the gap being a filter. The rotation of the inner body creates Taylor vortice which continuously displace occluded solute on the filter surface. The filter can be a membrane.

An apparatus for performing an operation on a fluid material to separate liquid from solid matter within the fluid material The apparatus comprises a belt structure movable along a path. The belt structure comprises a belt portion adapted to be assembled into a movable tubular structure within which at least part of the operation is to be performed. The tubular structure is permeable to liquid for separation of liquid from solid matter within the fluid material. The tubular structure is continuously assembled at one end thereof and continuously disassembled at another end thereof during movement of the belt structure. The path includes a descending portion along which the assembled tubular structure passes, the descending portion being inclined whereby at least some of the solid matter within fluid material in the tubular structure is caused to move downwardly along the descending portion under the influence of gravity to facilitate cleaning of the permeable tubular structure.
摘要:
An apparatus and method for filtration of solid particles and organisms from a flowing liquid and for cleaning filter elements while maintaining a positive flow of filtered liquid from the system while so cleaning. Turbulent liquid flow, ultraviolet radiation and system pressure are disclosed aspects of the apparatus and method.

A fluid filter apparatus includes a first surrounding sidewall having inlet and outlet apertures, with first and second end portions, a cover attached to the second end portion and a domed end attached to the first end portion. Also included is a second surrounding sidewall with primary and secondary end portions, being co-axially disposed within the first surrounding sidewall, with a first environment interior disposed therebetween, a second environmental interior disposed within the second surrounding sidewall, and a third environmental interior disposed within said first surrounding sidewall. Further included is a primary strainer disposed between the first and second environments, a vane forming a helical channel within the first environmental adding a centrifugal velocity to the fluid to separate heavier fluids and particulates. Also, a secondary strainer is between the second and third environments, and a filter media is in a third environment.

The present invention discloses a system and method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.
