Process for making a microfiltration, ultrafiltration, pervaporation or reverse osmosis membrane for suspensions, emulsions or gas separation

摘要

In the process for producing a membrane (1) for microfiltration, ultrafiltration, pervaporation or reverse osmosis of suspensions, emulsions or for gas separations, a tubular membrane (1) wound from wire is used. Substances which form a fine separation layer (4) are introduced between the membrane coils (2) loosely in front of the membrane pores (3). This fine separation layer (4) is formed from substances present in the feed or added to this. IMAGE
