This 70-minute webinar examines the ASCE Standard for the Measurement of Oxygen Transfer in Clean Water and its role in determining lagoon aeration efficiency. We’ll cover why and how the test is performed and its relevance in aeration system design. You’ll also learn how to apply a critical eye to manufacturers’ efficiency claims.
- Why conduct Clean Water testing? What testing data reveals about aerator performance
- What is the ASCE testing process? About the standard; how clean water testing is performed
- Aeration technologies: comparison of clean water testing performance of different aerator types
- Clean Water testing as a basis for aeration design: calculation of SOTE and SAE, power demand, aerator placement; the alpha factor
- A grain of salt: evaluating manufacturers’ efficiency claims; how the ASCE test can be gamed
