Abstract

See full text

In known membrane filter modules the sealing of the inlet of the faces of the capillary or hollow fiber membranes relative to the inlet of the stainless steel filter housing suffers from loosening of the sealing compound from the housing and from ruptures within the sealing compound due to different extension coefficients of the materials employed. With the inventive membrane filter module the safe employment of stainless steel filter housings with sealings and fluid distributing heads made of plastic is possible. At least a portion of the outer mantle surface of the end of the membrane bundle which is enclosed by a sealing compound or fused with plastic material is exposed so that the exposed outer mantle surface of the end of the membrane bundle may cooperate with sealing elements. Due to the fact that the sealing no longer acts on the stainless steel housing a simple and safe combination of the membrane filter module with the fluid distributing heads made of plastic is achieved.
