[Membrane separation methods in water treatment. Fundamentals and technical applications (author's transl)]

The separation of material by means of synthetic membranes is increasingly gaining access in industry, and membrane separating processes have been mainly developed for the treatment of watery systems. This paper is intended to outline how membrane separating plants are to be designed. Starting from the basic process at the membrane, the material exchange behaviour of the single element (pipe, plate) and of the technical apparatus (module) is dealt with. Successful applications are used to demonstrate how the module can be fitted into an optimally working plant.
