Abstract: A cross-flow filter assembly (10) including: a cylindrical filter (12) having an inner periphery (14) enclosing filter region (26) extending along an axis (X) from an opposing feed end (16) and an effluent end (18); and a cleaning assembly (32) axially-aligned within the filter region (26) and comprising at least one radially extending cleaning member (34) biased against the inner periphery (14) of the filter (12), wherein the cleaning assembly (32) is adapted to rotate about the axis (X) to remove debris from the inner periphery (14) of the filter (12); and is characterized by a compressive member (40) providing a continuous radially outward force that biases the cleaning member (34) against the inner periphery (14) of the porous screen (24).

Abstract: A hydroclone comprising: a tank (12) including a fluid inlet (14), a filtered fluid outlet (16) and an inner peripheral wall (22) enclosing at least one chamber (24); a filter assembly (26) located within the chamber (24) and comprising a circular filter screen (27) centered about an axis (X); and a cleaning assembly (48) comprising at least one cleaning member (52) biased against and adapted to rotate about the periphery (29) of the filter screen (27); and at least one of: a) the filter screen (27) is reversibly deformable a radial distance (D) of from 0.1 to 10 times the average pore size by the cleaning member (52) biased against the periphery (29) of the filter screen (27); and b) a compressive member (58) providing a continuous radially inward force that biases the cleaning member (52) against the periphery (29) of the filter screen (27).

Abstract: A device for venting a processing vessel (2) comprising: a separation unit (20) including a fluid permeable separator (26) for separating a solid from a fluid present in a fluidic solid dispersion, the separation unit (20) having an interface component (22) for attachment to a wall (8) of a processing vessel (2) in a manner so that the interface component generally integrates with the wall forming a substantially contiguous wall surface and a cleaning mechanism (50) that is in fluid communication with the separation unit (20) and that is adapted to extract the fluid that is separated from the fluidic solid dispersion from the processing vessel, and to periodically and/or continuously agitating the solids on the surface of the separation unit so that the fluid can pass through the separator.
