✦ Synopsis

The tubular ceramic membrane system prepared by us consists of a substrate which is made by means of extrusion, and a microfiltration layer which is about 30 pm thick and which is applied by a film coating technique. This two layer system can also be used as a substrate for an ultrafiltration or gas separation membrane layer which is then also applied by a coating technique. The water fluxes for different substrate-MF layer combinations are given and the influence of the substrate permeability on the total permeability is discussed. It is also shown by the permeability of some gases that the three layer system can be used for gas separation.
