Patent number: 11000791Abstract: A rotary disc filter includes one or more filter discs secured to a rotary drum and include a series of circumferentially spaced backwash guides disposed in the filter disc. During backwashing, the backwash guides function to engage a mixture of backwash and suspended solids and guide or direct the mixture to a sludge trough disposed in the disc filter. The backwash guides generally assure that a greater percentage of the backwash and suspended solids mixture end up in the solids trough.Type: GrantFiled: March 6, 2019Date of Patent: May 11, 2021Assignee: Veolia Water Solutions & Technologies SupportInventors: Johan Gustav Alexander Jibert, Emil Svensson, Filip Thysell, Per Larsson

Patent number: 10729994Abstract: A disc filter includes a filtrate holding tank disposed below a series of disc-shaped filter members supported on a drum. Filtrate from the holding tank is used to backwash filter media on the disc-shaped filter members. Filtrate is discharged from the holding tank via a filtrate conduit. Bypass water is directed through a bypass conduit in the disc filter and mixed with the filtrate downstream of the filtrate holding tank. This assures that the filtrate used to backwash the filter media does not include bypass water.Type: GrantFiled: December 3, 2015Date of Patent: August 4, 2020Assignee: Veolia Water Solutions & Technologies SupportInventors: Emil Svensson, Kjell-Ake Svensson, Per Larsson

Patent number: 7597805Abstract: A rotary disk filter and a module for building a filter support for a rotary disk filter are disclosed. The rotary disk filter may comprise a drum, which is rotatable about its central longitudinal axis. The rotary disk filter may be adapted to receive a liquid which is to be filtered. In one implementation, the rotary disk filter may comprise at least one disk-shaped filter member which on the outside of the drum extends outwards in the transverse direction of the drum, and which has a filter support and at least one filter portion supported thereby. A first liquid duct may extend from the drum through the filter member and out through the filter portion. The filter portion may be made of filter segments, which are detachably secured to the filter support. At least one second liquid duct may extend between adjoining filter segments to provide liquid communication between the filter segments.Type: GrantFiled: February 24, 2004Date of Patent: October 6, 2009Assignee: Hydrotech Veolia Water Systems AktiebolagInventors: Åke Danielsson, Åke Ralvert, Emil Svensson, Per Larsson
