Membranes in Industries
Membranes are between the most important engineering components in use today, and each year more and more effective uses for membrane technologies are found. For example industrial effluent treatment, water purification, solvent dehydration by per-vaporation, recovery of volatile organic compounds and protein recovery etc. Membrane technologies are progressively becoming important components of pharmaceutical production processes. For some time, membrane separation technologies of reverse osmosis, ultrafiltration and microfiltration have been used to concentrate and purify both small and large molecules. Membrane science and technology is an increasing field and has become a projecting part of many activities within the process industries. It is relatively easy to identify the success stories of membranes such as desali nation and microfiltration and to refer to others as developing areas.
