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),
operating a membrane separation unit is not possible at all. Membrane
material properties depend on the structure of each layer and the (pore)
defect structure of each layer. Especially the latter becomes of crucial
importance in scaling up from lab scale membrane areas of a few cm2 to the
large surface areas needed for commercial applications. Colloidal processing
is the key to control the structure of an inorganic membrane on all these
three levels. 16 refs.
