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 present invention is a method of using crumb rubber from recycled tires as a filter media. The use of crumb rubber as a media differs from conventional sand or anthracite filters in several ways. The crumb rubber media is compressible which allows the porosity between rubber particles to decrease through the filter bed. The crumb rubber media compresses as headloss increases, allowing for better effluent quality late in the run. The crumb rubber media allows greater depth filtration. The crumb rubber media can be used at high filter rates, greater than 20 gpm/ft2. The crumb rubber media performs similarly to other traditional filter media in respect to turbidity and total suspended solids removal. The crumb rubber media properties are closely tied to media size and shape, with smaller media providing better effluent qualities and larger media allowing longer filter runs at higher flow rates.

Abstract: A filter device for filtering flowing liquids comprises a compressible filter medium in a vessel and a device by which the filter medium can be compressed by means of an actuation handle, so that impurities can be pressed out of the filter medium. In addition, the filter device contains a multipath regulator which can be adjusted for filtering, back-rinsing and clear-rinsing by means of three flow paths. It is also possible for the filter device to be outfitted exclusively with a multipath regulator or a compressing device.

Abstract: A concentrator for concentrating the fine solids of a liquid feed suspension has a shell within which there is a bundle of microporous fibers. Pressurized feed suspension is introduced through an inlet and passes over the external walls of the fibers with the clarified liquid being drawn from the lumens of the fibers and the concentrated feed being discharged through an outlet. The solids retained within the shell are removed by first applying a pressurized liquid and then applying a gas at a pressure sufficient to ensure that the gas will pass through the larger pores of the fibrs to remove the solids from the shell through the outlet to an external collection point. The fibers are enclosed within a variable volume diaphragm located within a diaphragm holder by spaced plugs. The volume of the diaphragm is altered by varying the pressure of a fluid introduced through the inlet to the space between the diaphragm and the diaphragm holder.
