Taking an integrated, cross-disciplinary approach to this critical process, Aeration Control System Design comprehensively addresses the concept and system design of aeration activated wastewater treatment. Author Thomas E. Jenkins, a veteran in the field, covers complete treatment of aeration system controls, processes, and instrumentation and includes a theoretical and mathematical treatment of case histories, complete with design procedures and analysis methodology. Equations, charts, figures, and diagrams are used extensively throughout, making this a vital resource for civil/environmental engineers, mechanical engineers, and electrical/instrumentation more
