H. David Stensel
Basic reactions, design principles, current design models, and operational considerations for biological treatment systems used in environmental engineering. Applications include activated sludge design and optimization, fixed film reactors, nitrification, nitrogen removal, phosphorus removal, anaerobic treatment, biomethane production, resource recovery, and toxic organics removal. Prerequisite: CEE 540 and CEE 482 or equivalent.

Student learning goals
• Objective 1: Understand concepts of the distribution of substrate utilization between that oxidized and that ending up as biomass on a COD basis.
• Objective 2: Understand the importance and use of solids retention time (SRT) in biological process design
• Objective 4: Be able to perform a mass balance to follow any specific component in a biological suspended growth process under steady state or dynamic conditions
• Objective 5: Design activated sludge systems for organics, nitrogen and phosphorus removal with conventional clarifiers or with membrane separation.
• Objective 12: Understand the design basis for key fixed film processes and the importance and effect of diffusion limitations in fixed film processes
• Objective 13: Design anaerobic digestion and other key anaerobic processes.
