When it comes to water and wastewater treatment facilities, environmental engineers quickly discover that knowledge of chemical, physical, and biological processes is not enough to ensure a workable design and trouble-free operation. The success of a treatment system depends to a significant degree on the system¿s fluid flow¿that is, on the selection and arrangement of pipes, channels, valves, pumps, and other hydraulic components that move fluid through the system. Treatment System Hydraulics addresses the nuts-and-bolts of treatment systems, examining typical variables and describing methods for solving the problems faced by practitioners on a daily basis. The book begins with an introduction to treatment systems and hydraulics and explains the basic concepts of fluid properties, fluid statics, and fluid flow. Then Bergendahl discusses the factors that shape engineering decisions: friction in closed conduits, pumps and motors, granular media, valves, instrumentation, materials and corrosion, effects of transient conditions, and open channel flow. Each chapter presents fundamental concepts and applications in diverse situations, along with worked examples and problem sets. Suitable for undergraduate and graduate courses, Treatment System Hydraulics is also an useful reference for environmental, mechanical, civil, and chemical engineers designing or managing water treatment facilities.

Choice Review

Bergendahl (Worcester Polytechnic Institute) aims to provide a nuts-and-bolts approach to the hydraulics of process design and analysis. Readers must thoroughly understand fluid mechanics fundamentals to use this work. Although the basic topics included are good and traditional, in many cases they are quickly covered and the relevance to the design process is lacking. For example, Net Positive Suction Head (NPSH) is not related to the specific speed and the suction-specific speed of the pump to prevent cavitation. Obviously, Bergendahl is very knowledgeable in the field of process hydraulics, but in the desire to assemble a nuts-and-bolts work, he assumes that readers have a comprehensive knowledge of the practical aspects of hydraulic design. The inclusion of topics like motor selection, corrosion and material selection, flow through porous media, and instrumentation are unique to a hydraulic monograph and provide a valuable source of information. The photographs need improvement as they are too dark; however, the illustrations are good. Though a book of this nature is needed, the text could be improved with further explanation of some basic topics. Examples illustrating the dynamics of flow through a plant and proper selection of mechanical equipment and pipes would have been invaluable. Summing Up: Recommended. Only comprehensive upper-division undergraduate and graduate collections. R. P. Carnahan formerly, University of South Florida
