Patent number: 6558545Abstract: The invention encompasses a system for the cross flow filtration of fluid media using membranes. The system has in a first embodiment two shafts, only one of which is hollow, with each shaft running through an axis of its given disc. The disc of each shaft is positioned offset with respect to one another to have a region of overlap therebetween. The region of overlap serves to enhance the efficient operation of the system by reducing the degree of settling of retentate on the disc of the hollow shaft, because of the wiping or cleaning effect achieved upon rotation of each shaft by a drive system. In another embodiment, both shafts are hollow.Type: GrantFiled: May 22, 2000Date of Patent: May 6, 2003Assignee: AA FlowSystems GmbH & Co.

Patent number: 6461503Abstract: There is provided an apparatus for the filtration of fluid media, in particular for the pre-screening of media, that has a primary pack of hollow discs, which are arranged parallel to each other at regular distances to each other, the walls of which are made of a sieve material. The apparatus also has a primary, hollow shaft, which penetrates and is fixed to the hollow discs, connecting its interior to the cavities of the discs, and is fitted with a drive. Also included is a secondary pack of discs, which are arranged similarly to the hollow discs of the primary pack. There is a secondary shaft that is arranged similarly to the primary shaft. The two packs with their respective shafts are designed and arranged in such a way that the discs of one pack protrude into the spaces between neighboring discs of the other pack. There is a container that encloses the packs and the shafts. The container has an inlet for the medium to be treated, as well as an outlet for the retentate.Type: GrantFiled: May 22, 2000Date of Patent: October 8, 2002Assignee: aaflosystems GmbH & Co.

Patent number: 5454947Abstract: A filter element intended for tangential-flow filtration has an elongated support body of porous ceramic material with coaxial channels running through the support body and provided on their surface with a ceramic membrane having a calibrated pore structure. A portion of the fluid flowing through the channels penetrates the membrane and exits as filtrate at the circumferential surface of the support body. The shape of the outwardly facing channel wall is adapted to the external shape of the support body and there it has a uniformly thick wall corresponding to the mechanical stress. The shape of the channel walls is configured such that the webs remaining between the channels flare outwardly wedge-wise. The filter element thus configured has a support body with a reduced resistance to the passage of the filtrate flowing through it.Type: GrantFiled: April 15, 1994Date of Patent: October 3, 1995Assignee: Cerasiv GmbH Innovatives Keramik-EngineeringInventors: Hans Olapinski, Winfried Michell, Manfred Kielwein, Hans-Erich Simmich, Helmut Ziegelbauer
