Summary: "Proper engineering and execution of aeration control systems is of prime importance to treatment plants, representing a significant savings in labor and energy costs. 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. Covering complete treatment of aeration system controls, processes, and instrumentation, this hands-on text provides civil and environmental engineers, mechanical engineers, and electrical/instrumentation engineers with theoretical and mathematical treatment of case histories, complete with design procedures and analysis methodology"-- Provided by publisher.
