The membrane module comprises essentially a cylindrical pressure tube (10), a rolled membrane element (12), arranged inside the pressure tube (10), and a connecting body (14) which can be inserted in a pressure-sealed manner into each open end of the tube (10). The latter contains a thin-walled duct (16) made of glass fiber-reinforced plastic, the ends of which are reinforced by insertion elements (18). The latter are advantageously plastic or metal precision-made rotary elements which have all the requirements, such as inner threads or inner grooves for reliable connection with the connecting bodies (18). |
