Abstract
The invention relates to a diagonal flow filter module, particularly for ultra- and microfiltration. The diagonal flow filter module consists of a cuboid stack element (5) with alternating flow channels (9) for crude solution or retentate and filtrate channels (10), which are separated from one another in each case by a filter membrane (6). The flow channels (9) are closed off at the side walls of the stack element (5), while the filtrate channels (10) have openings at the side walls for the discharge of the filtrate. The flow channels (9) are open at the end faces of the stack element (5) and the filtrate channels (10) are closed. The ends of the stack element (5) are sealed to a housing (1) with a synthetic resin composition. Sealed to the end faces there are end caps (12) with the connections for crude solutions and retentate which, together with the seal between the stack ends and the housing (1), ensures a reliable separation between retentate and filtrate space. The filtrate leaves the stack element (5) at the side walls, is collected in the housing (1) and withdrawn through one or two drainage connecting pieces. The diagonal flow filter module has an improved flow guidance system and permits a larger connection cross section to be realized.
