Patent number: 8444862Abstract: A rotary disc filter device comprises a rotary drum and a plurality of disc-shaped filter members secured about the drum. Each disc-shaped filter member has a filtering material disposed on the outside thereof. A guide bar extends longitudinally across the disc-shaped filter members and has a movable carriage mounted thereon. One or more nozzles are operatively connected to the carriage for delivering cleaning fluid onto the filtering materials. The guide bar is rotates between a cleaning position and an adjustment position. When the guide bar is in the cleaning position, the nozzle is disposed adjacent to one of the disc-shaped filter members such that the nozzle is positioned to deliver cleaning fluid onto the filtering material. When the guide bar is in the adjustment position, the carriage is movable along the guide bar without interference from the disc-shaped filter members.Type: GrantFiled: January 17, 2012Date of Patent: May 21, 2013Assignee: Veolia Water Solutions & Technologies SupportInventor: Ake Ralvert

Publication number: 20060260999Abstract: 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: ApplicationFiled: February 24, 2004Publication date: November 23, 2006Inventors: Ake Danielsson, Ake Ralvert, Emil Svensson, Per Larsson
