Publication number: 20050173318Abstract: A device for cross-flow filtration includes a plurality of linear filtration modules arranged parallel to each other and branching from a manifold arranged such that a flow transverse to the front surface of the filtration module is generated in front of all filtration modules. A constant flow velocity transverse to the front faces of the filtration modules is achieved by reducing the open cross-section of the manifold in the direction of flow, the reduction being continuous or stepwise. By avoiding the build-up of fibrous clumps, the fault-free operating time of filtration device can be significantly lengthened with relation to a conventionally embodied filtration device.Type: ApplicationFiled: June 17, 2003Publication date: August 11, 2005Inventor: Eduard Hartmann

Patent number: 6375847Abstract: The method relates to the operation of a cross-flow filtration installation for a product. This installation includes a filtration module (6), a pipeline (3) for the inflow of the product, a pipeline (9) for removing the product, a pump (4) with an electric motor (12) for recirculating the product, and a control valve (5′) for setting the conveying flow (Q1) of the pump (4). In order to make possible the maximally possible filtration output, based on the installation, along with a high proportion of solids of the product, without endangering operational safety by means of overloads, the strength of the operating current (i1) of the electric motor (12) is measured. The operating current (i1) is adjusted to a maximally, permissible value via a regulator (20) by setting the conveying flow (Q1) of the pump (4) by adjusting the flow control valve (5′).Type: GrantFiled: March 1, 1999Date of Patent: April 23, 2002Assignee: Bucher-Guyer AGInventor: Eduard Hartmann

Patent number: 6113791Abstract: The process for flushing filtration modules of a cross flow filtration device is carried out in a unit that is used for the clarification of liquids in a retentate circulation circuit. When the unit is shut down, for example as the result of a power failure, filtration modules are flushed free of solid particles by the supply of an addition of flushing agent that increases over time and/or geometrically into the retentate side of the cross flow filtration device. As a result, the danger of clogging of the filtration modules is largely avoided.Type: GrantFiled: March 3, 1992Date of Patent: September 5, 2000Assignee: Bucher-Guyer AGInventor: Eduard Hartmann

Patent number: 6083390Abstract: The system includes a number of membrane modules (1-8), each including one membrane tube or a bundle of a plurality of membrane tubes, whose walls have the function of separating membranes, as well as a tubular module housing for receiving the membrane tubes. Each membrane tube (1-8) has one connecting flange (20, 21) each for delivering and removing the retentate, as well as four further laterally disposed connecting flanges (22-25) for removing the permeate. These connecting flanges (22-25) retain the membrane modules (1-8) in self-supporting fashion in their group.Type: GrantFiled: September 10, 1998Date of Patent: July 4, 2000Assignee: Bucher-Guyer AGInventor: Eduard Hartmann

Patent number: 5958244Abstract: For thickening a retentate by means of membrane filtration (ultra-/micro-filtration) to obtain the highest possible wet sludge proportion, a gaseous medium is admixed with the retentate. To this end an open feed line (13) above the retentate level (14), a porous ring (17) in the retentate, or a simple line connection (19, 20, 28, 29) in a tank (6) are proposed. A number of advantages accrue as a result of the lowering of the viscosity of the retentate achieved in this way, such as savings of energy for retentate recirculation, efficient installations because of longer series or passes of filtration modules, and savings in squeezing installations because of the direct filtration with high solid components.Type: GrantFiled: January 16, 1997Date of Patent: September 28, 1999Assignee: Bucher-Guyer AGInventor: Eduard Hartmann
