Abstract
A membrane type filtering device has modules containing bundles of capillary tubular membranes. To meet various filtration problems the modules have double accesses located at the two end faces of the module housings. Connections to these accesses are made by plugging in the module ends into flow distributor heads, which can be of two types whereby the crossflow can be selectively conducted either through the internal passages of the capillary membranes or else along the outsides of the capillary membranes. Appropriate matching is achieved by exchangeable inserts and exchangeable intermediate tension plates and end tension plates.
