The process increases the performance of a cross-flow filter assembly (9,96) in modules (1), in which the retentate (7,31) and the permeate pass through chambers (8,10,66). A required trans-membrane pressure (TMP) can be set between the two sides of the cross-flow filter (9,96). The permeate chambers (10,66) are linked in a permeate fluid circuit (13,43). The flow resistance profile within the permeate circuit (13,43) is chosen to match the flow resistance in the retentate chambers (8). The pressure on the permeate side, esp. the minimal pressure and the permeate flow through the permeate circuit (13,43), is such that the profile in the retentate along the cross-flow filter (9, 96) is formed by the profile in the permeate, and the TMP along the cross-flow filter adopts a predefined value on at least one point on each filter. Also claimed is an assembly for the above process. |
