Abstract
The system includes a number of membrane modules (1-8), each including one membrane tube or a bundle of a plurality of membrane tubes, whose walls have the function of separating membranes, as well as a tubular module housing for receiving the membrane tubes. Each membrane tube (1-8) has one connecting flange (20, 21) each for delivering and removing the retentate, as well as four further laterally disposed connecting flanges (22-25) for removing the permeate. These connecting flanges (22-25) retain the membrane modules (1-8) in self-supporting fashion in their group.
