With well over 6,000 pertinent references, this is a practical 'how to do' for either reengineering existing technologies or implementing innovative processes. After an introduction to the development of clean technology concepts, the first part looks at the theory and engineering of membrane processes. Part 2 deals with membranes in such industries as water, textiles, paper, metal plating, pharmaceuticals and food. The final part discusses materials management, including metals, acids, and hydrocarbons separations. Finally, an appendix lists membrane manufacturers and companies dealing with clean technologies, as well as various lists of toxic, harmful or prohibited substances.
