Preparation of Synthetic Membranes,t which enable a membrane to be constructed from a given material. The kind of technique employed depends mainly on the material used and on the desired membrane structure (which in turn is dependent on the separation problem). Three basic types of membrane can be distinguished based on structure and separation principles:

Favorable

Characterisation of Membranes, membranes may differ significantly in their structure and consequently in their functionality. Many attempts have been made to relate membrane structure to transport phenomena, in an effort to provide a greater understanding of separation problems and possibly predict the kind of structure needed for a given separation.

Transport in Membranes,e phase to another because a force acts on that molecule or particle. The extent of this force is determined by the gradient in potential, or approximately by the difference in potential, across the membrane (ΔX) divided by the membrane thickness (.), i.e.

Polarisation Phenomena and Membrane Fouling,tion, the membrane performance (or better the system performance) can change very much with time, and often a typical flux-time behaviour may be observed: the flux through the membrane decreases over time. This behaviour is shown schematically in figure VII — 1 and is mainly due to concentration polarisation and fouling.
