Abstract: A method for filtering and backwashing solid particles out of liquids is illustrated, with a filter drum (5) positioned completely below the liquid level (6) having a cylindrical surface (7) coated with a filter medium (8), the liquid flown through the outside of the filter drum to the inside. A backwashing device for removal of the filter cake from the filter medium is provided. At the beginning of each cycle of backwashing an air cushion (15) is introduced in the filter drum (5) and liquid in the filter drum (5) is displaced in such a manner so that liquid jets from an ejetion apparatus (19) containing a spraying head (17) and being arranged in the interior of the filter drum without being sealed on the filter drum penetrate through the air cushion (15) to the backside of the cylindrical surface (7) of the filter drum (5). The filter cake so removed from the filter drum is withrawn at the outside of filter drum (5) in a stream of liquid.

Abstract: 387,339. Filters. BURRELL, B. S., 3502, Fir Street; East Chicago, U.S.A. July 22, 1931, No. 20963. Convention date; June 23, 1930. [Class 46.] A rotary strainer drum comprises two cylindrical shells with coincident apertures and an intermediate straining medium, the apertures in the shell through which the fluid passes first being such as to form pockets for the retention of the solid matter. A straining element, comprising wire gauze held between perforated cylinders 28, 29, Figs. 1 and 2, fits closely in a stationary liner 13 in a casing 9 with its ends in annular bearing sockets sand is rotated by means of a shaft 36. Liquid or gas from an inlet 10 passes through Openings 14 in the liner, and the wall of the straining element and is delivered axially through an outlet 21. A member 37, which is pivoted to rest against a longitudinal section of the element opposite to the inlet 10, directs a portion of the strained fluid through a tapering slot 43 and outward through this section of the element so that impurities, carried round from the inlet 10 in the pockets formed by the apertures in the outer cylinder, are fluahed away through a slot 15 of the liner 13 to a waste outlet 17. In a modification shown in Figs. 4 and 5 the interior of the strainer is divided into compartments by a partition 74. The fluid enters axially and strained fluitl passes away through an outlet 67. A portion of the strained fluid is led back through a passage 90 and directed by a slot 91 in the liner 65 inwardly through a section of the strainer to the compartment behind the partition 74, flushing impurities away through a waste outlet 93. The Specification as open to inspection under Sect. 91 comprises also apparatus shown in Fig. 4 (Cancelled) in which the wire gauze is not protected by an inner perforated cylinder. The fluid enters through a pipe 50 and the main ,part is directed by a partition 59 to pass outwardly through the strainer to an outlet 47. A part, however, passes through apertures 60 and flushes solid matter from that part of the strainer, separated from the outlet 47 by the partition 59, away through a waste outlet 62. This subject-matter does not appear in the Specification as accepted.

Abstract: A backflushing filter having an inlet, an outlet, and a drain; a filter that divides a housing into an inlet chamber that is connected to the inlet and an outlet chamber that is connected to the outlet; a backflushing device having a suction element arranged so that it is able to rotate around the filter on the inlet side of the housing with at least one suction opening that is oriented in the suction direction toward the filter for filter-cleaning purposes; a backflushing duct connected to a suction opening and the drain; and a rotating device which drives the rotational movement of the suction element around the filter when a pressure drop occurs in the backflushing duct; wherein when the pressure drop in the backflushing duct occurs, the rotating device drives the rotational movement of the suction element by the suction direction of the suction opening that is inclined relative to the radial direction of the suction element.

Abstract: A fluid filtering apparatus such as for filtering particulates and other materials from treated water includes a tank and a filtering region configured as a plurality of individual effluent regions, defined in part by channel frames, disposed between a plurality of influent regions interposed between the effluent regions. A double sided backwash shoe is scannable in the influent regions, to simultaneously clean opposed filter media exposed thereto. The backwash shoe is free to move inwardly and outwardly of the opposed filter media. Additionally, the backwash shoe includes an end opening, positioned adjacent to the base of the tank, to remove sludge and particulates which have settled to the area near the base of the tank while backwashing a filter media.

Abstract: A filter for filtering a flow of liquid a filter assembly with a number of filter disks coaxially arrayed along a central flow path within a pressure vessel. Each filter disk has a number of segments. The segments are preferably implemented as spacers with outward-facing filler screen support configurations supporting first and second filter screens. The filter screen support configurations have a cellular form that is open over a majority of a surface area, An arrangement of support ribs are deployed to maintain a spacing between the first and second filter screen support configurations. At least 80 percent of an internal volume of each of the segments is preferably open to allow liquid flow from the screens to the central flow path. Also disclosed are modular structure's of the filter disks, and a backwash arrangement which performs a spiral scanning motion across the surface of each filter disk.

Moreover, said cleaning head has an opening of adjustable size facing said internal surface of said filter element and providing fluid communication between the interior of said housing and the interior of said pipe. The filter module further comprises means for creating a pressure difference between the interior of said housing and the interior of said pipe so as to cause a fluid flow from the interior of said housing to the interior of said pipe as well as means for effecting a rotation of said pipe. Said filter module further comprises a spacer element rotatably supported on and releasably attached to said cleaning head, said spacer element defining the minimum spacing between the cleaning head and the internal surface of said filter element.

Abstract: Methods and apparatus for treating water and wastewater include the step of flowing a suspended solids stream generally upward through a sludge blanket region of a cloth disk filter vessel, thus forming a partially treated effluent composition and a solids-enriched sludge blanket. The partially treated effluent composition is allowed to flow generally upward to a cloth filter zone in the vessel after contacting the sludge blanket. The methods include flowing the suspended solids stream through one or more distribution headers positioned in the sludge blanket. An option is to provide a sludge concentration zone in the sludge blanket region, allowing sludge to flow into the sludge concentration zone to form concentrated sludge. Other methods and apparatus include backwash assemblies that backwash substantially the entire filter cassette surfaces, with or without use of a sludge blanket zone. Either the backwash assemblies or filter cassettes move in the latter methods and apparatus.
