A filtration system for a fluid containing suspended particles mounts a filter (3) within a closed container (2) having fluid inlet (7) and outlets (8, 9) for filtered fluid and retentate fluid. The inlet and outlets communicate with the interior of the container but do not rotate with respect to the container. An orbital and/or oscillatory drive (1) moves the container in either a continuous wobbling movement or in an oscillatory movement. In one form a mechanical element (4) pivots around the inlet side of the filter. In another form a rotating cylinder (17) with an eccentric center of gravity revolves or oscillates with respect to a surrounding non-porous cylinder (18) to create Taylor vortices in the fluid. In another, direct-drive form, a conduit (92) to the interior of a closed filter element (3), or a surrounding sleeve (77) which supports the container (2) is formed of an elastically resilient material. |
