Patent number: 7708887Abstract: Described herein are methods and systems for combination membrane/biolytic filtration. In one embodiment a filtration system is operated under suction. The arrangement includes a feed tan (5) having a smaller filtrate vessel (6) positioned therein. The region within, the feed tank (5) not occupied by the filtrate vessel (6) is partially filled with layers of decomposing and decomposed solid organic waste material to form an aerobic filter bed (7) of the type used in biolytic filtration as described above. A further module vessel (8) is mounted within the filtrate vessel (6) to form a membrane chamber (9) containing a membrane filtration module (10).Type: GrantFiled: November 8, 2006Date of Patent: May 4, 2010Assignee: Siemens Water Technologies Corp.Inventors: Warren Thomas Johnson, Bruce Gregory Biltoft, Dean Osman Cameron

Patent number: 7264716Abstract: A membrane filtration manifold for connecting a filter submodule including one or more elongate bundles of semipermeable polymeric fibers is provided. The manifold includes a housing and connecting collar connected with said housing. The collar is adapted to receive and locate the submodule, where the submodule has a connecting sleeve with a locking formation. The submodule can be secured at one end to the collar by a clip adapted to engage both the collar and the locking formation to prevent axial withdrawal of the submodule from the collar. Also disclosed is a membrane filtration apparatus including a filter submodule including one or more elongate bundles of semipermeable polymeric fibers. The apparatus further includes a membrane filtration manifold removably connected at one end of said filter submodule and a basepiece removably connected to the other end of said filter submodule.Type: GrantFiled: November 20, 2003Date of Patent: September 4, 2007Assignee: Siemens Water Technologies Corp.Inventors: Warren Thomas Johnson, Gary William Stollery, Bruce Gregory Biltoft, David John Cox, Robert James McMahon, David Wood, Leon Keith Ernst
