Abstract:
Membrane material, membrane module design and system design all threedetermine the performance of membrane separation units. However, most
important are the membrane material properties. Without the use of membrane
materials that possess sufficient intrinsic selectivity and permeability for
the separation of a certain component(s) from a mixture (liquid or gas), a
membrane separation unit operation is not possible at all. Membrane material
properties depend on the structure of the usually tubular material on several
levels: the layered structure, the microstructure of each layer and the
(pore) defect structure of each layer. In particular the latter becomes of
crucial importance in scaling up membrane areas of a few cm2 to the large
surface areas needed for real applications. Colloidal processing is the key
to control the structure of an inorganic membrane on all these three levels.
