Biotechnology Second, Completely Revised Edition Edited by H.–J. Rehm and G. Reed in cooperation with A. Pühler and P. Stadler This fully revised and expanded Second Edition takes into account all recent developments in biotechnology. It is extraordinarily broad in scope, up–to–date, carefully structured and well–balanced. "Biotechnology" considers both basic concepts and widely–differing industrial applications: it is a successful synthesis of theory and practice. Any scientist aiming for success in industrial microbiology, biochemistry, molecular biology and chemical engineering must turn to "Biotechnology". Volume 11c presents an overview of solid waste management, off–gas treatment procedures, and drinking water preparation techniques that are well established or have been developed recently. Modern methods of solid waste management must, except for biotechnological alternatives, deal with the different incineration techniques for which experience is available or which are in an experimental or pilot scale state. Off–gas purification is recognized as an essential part of production and waste or wastewater treatment processes, and many different methods of waste gas purification can be applied today. This book outlines the basic biological and technological requirements. Last but not least, part of the volume is dedicated to drinking water preparation ?? a topic of great present and future importance for developed and developing countries. Topics included in Volume 11c are: ?? Bio– and Pyrotechnology of Solid Waste Treatment ?? Microbiology, Technology and Strategies of Composting ?? Anaerobic Fermentation of Garbage Waste ?? Landfill Systems ?? Combined Mechanical and Biological Treatment of Municipal Solid Waste ?? Hygienic Considerations ?? Process Engineering, Microbiological Aspects and Commercial Applications of Biological Waste Gas Purification ?? Bioscrubbers ?? Biofilters ?? Trickling Filters ?? Membrane Processes ?? Drinking Water Treatment ?? Groundwater Recharge and Bank Filtration ?? Biofilms ?? Biofiltration
