ABSTRACT:
A modular unit as a filtering apparatus for a membrane separation process, especially for treating water by reverse osmosis, includes a pipe which is open at both ends. A stack of membranes adapted to the inner diameter of the pipe can be inserted into the pipe. The stack of filter elements, which includes guide plates, carrier plates, and membranes, is clamped together by a central clamping bolt which passes through the filter element stack between two fixed pressure plates. Located at the peripheries of the pressure plates are inclined circumferential grooves in which are disposed sealing rings which, when excess pressure exists in the interior of the housing, are urged radially and axially outwardly, and thus effect a good seal between the inner wall of the pipe and the peripheries of the pressure plates.
