MATERIAL SEPARATING APPARATUS AND METHOD FOR PRODUCING SAME

The invention concerns apparatus for the separation of the constituent components of liquid solutions and gaseous mixtures, comprising a cylindrical housing 2 open at both ends and provided with a lateral inlet and/or outlet coupling 1. A capillary membrane bundle 4 is arranged in the housing 2 by being journalled in resin fittings 5, 6 which sealingly close the open ends of the housing 2. In order to realise more simply the orderly fixing of the membranes 4 and to enable a used-up capillary membrane bundle 4 to be readily exchanged the resin fittings of the construction according to the invention consist of a securing fitting 5 which gathers the ends of the capillary membranes 4 into an orderly bundle and a closing fitting 6 formed around the securing fitting 5 at the end of the housing 2. The closing fitting 6 is formed in a shape-locking manner with the internal wall of the housing 2 while at the same time being axially relatively displaceable in relation to the housing 2. The sealed closure of the housing is assured by a sealing ring 3 seated in an annular groove 11 formed in the internal wall of the housing 2 between the closing fitting 6 and the internal wall of the housing 2.
