process for manufacturing a membrane for mikrofiltration, ultrafiltration, pervaporation od. reverse osmosis of suspensions, emulsions or gastrennung.

摘要

In the process for making a membrane (1) for microfiltration, ultrafiltration, pervaporation or reverse osmosis of suspensions, emulsions or for gas separation, a coiled, tube-shaped wire membrane (1) is used. A pressure is applied axially to the membrane windings (2), and, as required, the pressure is then removed and reversed to give tension, so that the pores (3) between the windings (2) have an effective filtering distance from 1 nm upwards. Substances which form a fine separation layer (4) can be introduced into the membrane pores (3) between the membrane windings (2). …IMAGE…
