    摘要: An automatically cleanable milk filter includes a cylindrical housing with an outer wall, a first end with a first liquid connection, and above a second end with a second liquid connection. A concentric cylindrical filter part and a cylindrical core placed concentrically within the filter part are accommodated in the housing. The filter part includes wire having a tapered cross-sectional profile in a spiral shape or as a series of parallel rings or rods, and a frame for keeping them spaced apart, thereby forming a plurality of filter openings. The filter part divides the filter volume into a first volume part which is directly connected to the first liquid connection, and a second volume part which is directly connected to the second liquid connection. The second volume part includes a cylindrical part, as well as a top part which narrows at a transition to the second liquid connection.

    摘要: A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portions—each communicating with flow from one of the flow modifiers. The device can include one or more plates disposed adjacent one another within the internal hollow with a peripheral edge attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or one or more of the plates can define openings therein allowing passage of at least some fluid therethrough.

    摘要: A variable pore size filter media including an upper plate, a retainer, and a support profile disposed between the upper plate and the retainer. The variable pore size filter media also includes a plurality of wire rings disposed on the support profile and longitudinally distributed within a region between the upper plate and the retainer, the plurality of wire rings being distributed in a non-contiguous manner to form a plurality of spaces therebetween. The variable pore size filter media further includes a plurality of pores defined by the plurality of spaces between the plurality of wire rings and a pore size adjustment mechanism configured to vary a respective distance between each of the plurality of wire rings to increase or decrease a respective size of each of the plurality of pores by increasing or decreasing a size of each of the plurality of spaces.

    摘要: The invention provides novel slot tube screen material for filtering applications, in particular for separating solid particles from liquids. The slot tube filter screens manufactured according to the invention feature very small slot openings, which are narrowed with respect to a slot opening dimension of conventionally fabricated slot filter tubes. The slot tube construction of the invention comprises a torsion-rotation deformed structure of normally axially orientated parallel support members of the slot tube mantle, which further comprises spiral windings of profile wire around said support members, whereby at each contact crossing a solid weld connection fixes a crossing profile wire to a support member. The plastically twisted slot tube structure displays a helical distortion of the axial support ribs inside the slot tube. As a consequence the filter slot openings between adjoining windings of profile wire are markedly narrowed (versus undeformed slot tube), which offers the possibility of reliably achieving very small filter slot openings of less than 0.020 mm in slot tube filters or screens.

    摘要: A stormwater treatment system includes water treatment media that defines a helical flow path within a conduit. The water treatment media may include a plurality of helical water treatment media components that are constructed and arranged to seal against an inside surface of the conduit. The individual helical water treatment media components may be installed in situ within the conduit when the conduit is positioned within a chamber having an access opening, and periodically removed and replaced by passing the components to the access opening. The components further may have a flexible frame, which allows the water treatment media to dynamically adjust to swelling of the filtration media and other forces that may occur during use. The performance of the system may be adjusted by adjusting the helical pitch of the helical water treatment media components.

    摘要: A filter assembly and a method of filtering a fluid using the filter assembly are disclosed. The filter assembly includes wave coils arranged axially to define a filter element. The filter element includes bottom and top ends and an inner cavity. The filter assembly also includes a base plate that engages one, or both, ends to support the wave coils. The fluid flows toward the base plate, and the base plate diverts the fluid inside or outside the inner cavity. The wave coils include crests and troughs. engaging one another on adjacent wave coils to define filtration apertures. The diverted fluid is filtered through the filtration apertures such that a filtrate of the fluid passes through the inside or outside of the inner cavity, and a retentate of the fluid is retained on the other of the inside or outside of the inner cavity relative to the filtrate.
