Abstract: A filter element may include a filter medium extending in an extension direction and including a filter material separating clean and raw sides of the filter element, and two seals arranged at two end faces of the filter medium located opposite one another in the extension direction, so that an inner side of each seal may be arranged lying against the associated end face in a fluid-tight manner. The two inner sides, jointly with an inner circumferential side of the filter medium, may partly limit a filter element interior space. The filter medium, in a section running perpendicularly to the extension direction, has an open U-geometry or V-geometry with two legs.

Abstract: A cross-flow filtration system for filtering a suspension, such as but not limited to a viniculture suspension, may include a plurality of hollow fibre modules for retaining a retentate of the suspension. A circulation pump may be fluidically connected to the hollow fibre modules for facilitating a mechanical flow of the suspension. A flow distributor may distribute the suspension to the hollow fibre modules. A flow collector may collect the suspension of the hollow fibre modules. The flow distributor and the flow collector may be fluidically connected to the circulation pump and the hollow fibre modules. The hollow fibre modules may be arranged coaxially to each other about a longitudinal axis of the cross-flow filtration system.
