Patent number: 6634372Abstract: In an apparatus containing rotating filter media that removes solids from a fluid stream, the invention provides devices and methods for improved cleaning of the filter media. Solids trapped on the filter media are removed by the application of a pressurized fluid spray system. The spray system has nozzles distributed across a spray arm. The nozzles create a generally elliptical spray fan pattern in contact with the filter media. The nozzles are spaced and angularly oriented on the spray arm so that adjacent spray fan contact areas overlap. This distribution and orientation equalizes the distribution of the washing flow and hydraulic energy over the filter area, thereby maintaining the filter material in a more uniformly clean and effective filtering condition.Type: GrantFiled: October 24, 2001Date of Patent: October 21, 2003Assignee: Aqua - Aerobics Systems, Inc.Inventor: Eugen O. Bergmann

Patent number: 6306310Abstract: A concurrent backwash distribution apparatus for a filter having a filter tank and a plurality of underdrain laterals includes a baffle positioned in a common main conduit to define an auxiliary flume between the baffle and the underdrain laterals. The auxiliary flume is in fluid communication with the common main conduit and the underdrain laterals. The baffle has at least one flume liquid metering orifice preferably located near the bottom of the baffle so that it may be below a gas/liquid interface in the auxiliary flume during concurrent gas/liquid backwash operations. A flow distribution plate may be positioned between the auxiliary flume and the underdrain laterals, the flow distribution plate having at least one liquid metering orifice and at least one gas metering orifice. The baffle may take one of many forms. The baffle creates an adequate liquid pool in the common main conduit for low velocity flow of backwash liquid while at the same time providing uninhibited flow of backwash gas.Type: GrantFiled: July 28, 2000Date of Patent: October 23, 2001Assignee: The F. B. Leopold Company, Inc.Inventors: Eugen O. Bergmann, Richard W. Hsieh, John Geibel

Patent number: 6294098Abstract: In an apparatus containing rotating filter media that removes solids from a fluid stream, the invention provides devices and methods for improved cleaning of the filter media. Solids trapped on the filter media are removed by the application of a suction pressure that draws the filter media into contact with a backwash shoe. The backwash shoe has one or more orifice slots in a radially tapered or oblique angular configuration or in a combination of radially tapered and oblique angular configurations. The orifice slot configuration creates an hydraulic condition where the unit of orifice area applied per unit filter area has a generally uniform ratio across the rotating filter media. This configuration equalizes the distribution of the backwash flow over the filter area, thereby maintaining the filter media in a more uniformly clean and effective filtering condition.Type: GrantFiled: May 23, 2000Date of Patent: September 25, 2001Assignee: Aqua-Aerobics System, Inc.Inventor: Eugen O. Bergmann

Patent number: 5639384Abstract: An apparatus and method for gas backwashing a granular media supported upon a lateral underdrain is disclosed. The lateral underdrain includes a plurality of dispersion apertures therethrough and at least one liquid return conduit extending to a discharge at a level below the dispersion apertures. The present invention provides for equal distribution of backwash gas across the entire lateral underdrain by directing backwash gas through the dispersion apertures into the granular media and directing liquid from the granular media through the liquid return conduit without obstructing backwash gas flow through said apertures from a gas pocket formed underneath said apertures.Type: GrantFiled: February 5, 1996Date of Patent: June 17, 1997Assignee: The F.B. Leopold CompanyInventors: Marvin A. Brown, Eugen O. Bergmann, Richard Hsieh

Patent number: 5328608Abstract: An improvement for a filter system which distributes backwash fluid uniformly throughout a bed of granular media is disclosed. The filter system includes a distributor positioned beneath and supporting the media, with the distributor having a plurality of walls which define a primary horizontal conduit and a secondary horizontal conduit. At least one of the walls which define the conduits contains metering orifices that connect the primary conduit to the secondary conduit. The improvement includes at least one baffle positioned within the primary conduit to facilitate uniform flow of backwash fluid from the primary conduit through the metering orifices into the secondary conduit. The baffle may comprise flanges extending from the walls which define the primary conduit normal to a fluid flow direction in the conduit. Alternatively, the baffle may include posts positioned within the conduit.Type: GrantFiled: May 27, 1992Date of Patent: July 12, 1994Assignee: The F.B. Leopold Co., Inc.Inventors: Eugen O. Bergmann, Marvin A. Brown, Beverly Richard P.
