Abstract: A filter includes a filter chamber of adjustable volume. The filter chamber encloses a compactable filter medium through which fluid to be filtered may flow. The filter medium includes a plurality of filter particles. A filter particle has an initial shape and is deformable upon application of a deforming force, being capable of substantially regaining its initial shape upon removal of the deforming force. The porosity of the filter medium is adjustable by adjusting the volume of the filter chamber so as adjust the compaction of the filter medium.

Abstract: A high rate, upflow filtration system is described in which a compressible, fibrous lump filtration media is compressed to adjust the porosity and collector size of the media in the bed and to provide a porosity gradient within the bed proceeding from more porous to less porous in a direction opposite to the flow of fluid so that filtration proceeds in a direction from a more porous to a less porous filter bed. Larger particles are removed by the more porous media and successively smaller particles are removed as the filter bed becomes less porous. The system is capable of reducing the turbidity of influent municipal wastewater from about 8 NTU to about 2 NTU at a wastewater flow rate of from about 820 to 1230 L/m2·min (20 to 30 gal/ft2·min), at a bed compression ration of from about 15 to 40 percent, and at a backwash rate of from about 1 to 6 percent based on the total wastewater passing through the filter.

Abstract: The invention relates to a method of and an apparatus for filtering a medium. The apparatus has a filter housing and a supporting means located within the filter housing. A plurality of fiber bundles are attached to the supporting means and extend within the filter housing in direction between an inlet and an outlet. A flexible waterproof membrane is provided within the filter housing to constitute a pressure chamber. When pressurized during the filtration process, the membrane presses the plurality of fiber bundles to form a frustrum-like filter chamber. The medium becomes filtered as it passes through the frustum-like filter chamber.
