Aeration Considerations in the Design and Operation of Biological Nutrient Removal Processes

Thursday, April 11

Aeration system design and control is critical in the performance of biological nutrient removal (BNR) systems. Excessive aeration not only increases energy costs, but it can limit the reliability of BNR processes. During this session, discover solutions to common yet challenging impacts to BNR performance through 3 case studies.

Learner Outcomes:

Identify conditions where internal recycle flows with entrained DO are impacting anoxic zone performance and how to correct this issue.
Identify back mixing conditions and how to correct this issue.
Understand the benefit and how to implement effective flow and dissolved oxygen distribution.
