    Abstract: PCT No. PCT/SE95/01002 Sec. 371 Date May 15, 1997 Sec. 102(e) Date May 15, 1997 PCT Filed Sep. 7, 1995 PCT Pub. No. WO96/08300 PCT Pub. Date Mar. 21, 1996A filtering apparatus comprises: a pressure vessel; a plurality of filter elements arranged within the pressure vessel, the filter elements each having an upper end, a lower end and a side wall; filling bodies positioned within the filter elements; a first conduit for introducing compressed gas into the pressure vessel; a second conduit for transporting unfiltered liquid to and from the pressure vessel; and a third conduit for removing filtrate from the pressure vessel and transporting back-flushing liquid to and from the filter elements, the third conduit positioned proximate to a bottom portion of the pressure vessel and attached to the lower ends of the filter elements, such that the third conduit provides a support structure for the filter elements and the back-flushing liquid introduced via the third conduit fills the filter elements in a direction from the lower ends toward the upper ends, the volume of back-flushing liquid introduced into the filter elements limited by the filling bodies. A method of operating the filtering apparatus is also disclosed.

    Abstract: A system for removing material from a flowing liquid, where the system includes one or more cartridges, where each cartridge has an outer permeable wall and an inner permeable wall that form a media region between the walls, where a media is disposed within at least part of the media region to remove at least a portion of the material from the flowing liquid, the cartridge also having an inner cartridge lumen in communication with the inner permeable wall, and a cartridge outlet in communication with the inner cartridge lumen; a cartridge chamber having a treatment region that houses the one or more cartridges, where the cartridge chamber also includes a chamber inlet to accept the flowing liquid, and a chamber outlet to discharge treated liquid; and an actuatable valve positioned outside the one or more cartridges, where the valve controls a flow rate of the flowing liquid within the treatment region by actuating in response to a change in a level of the liquid in the treatment region.

    Abstract: A filter apparatus and coating method particularly adapted for thixotropic coating solutions and which yet permits the dead space within the housing of the filter apparatus for the secondary region to be reduced under a broad range of conditions at all times. The improved filter apparatus has a filter provided within a housing in such a way that it divides the interior of the housing into a primary region into which a coating to be filtered is supplied and a secondary region which receives the coating solution after it is filtered. The apparatus filters the coating solution just before it is coated on a flexible base. The apparatus is characterized in that the housing for the secondary region is designed in such a way that an index for measurement of the dead space within the housing satisfies the relation T/.tau.> 0.95, where .tau. is an experimentally determined dimensionless number for the indicial response time of the housing and T is a dimensionless number of theoretical time.
