This manual of practice guides process engineers in the design of wastewater treatment plants. It provides information on general modeling concepts, computer modeling terms, and best practices for using process models for the design of wastewater treatment plants of any size. After a brief history of process modeling, the manual contains chapters on modeling fundamentals, unit process model descriptions, process modeling tools, modeling protocols, defining objectives, building a plant model, and using models for design. Information is demonstrated with b&w diagrams and images. Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)
