Abstract
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.
