Size exclusion membranes technology

Commercial as well as potential uses of inoiganic membranes multiply rapidly in recent years as a result of the continuous improvement and optimization of the manufacturing technologies and applications development for these membranes. Most of the industrially practiced or demonstrated applications fall in the domains of microfiltration or ultrafiltration. Microfiltration is applied mostly to cases where the liquid streams contain high levels of particulates while ultrafiltration usually does not involve particulates. While their principal separation mechanism is size exclusion, other secondary mechanisms reflecting the solution-membrane interactions such as adsorption are often operative. Still under extensive research and development is gas separation which will be treated in Chapter 7.
