In other words, the demon is able to discriminate between molecules. Suppose that a vessel . divided into two parts A and B by a division in which the

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 an

Membrane Processes,r existing between two homogeneous phases. Transport through the membrane takes place when a driving force is applied to the components in the feed. In most the membrane processes the driving force is a pressure difference or a concentration (or activity) difference across the membrane. Parameters s

Polarisation Phenomena and Membrane Fouling,tion, e.g. a pressure driven process, 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
