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.
