Discover how the Los Angeles County Sanitation Districts are utilizing off-gas testing to optimize their secondary aeration performance. This technique allows for real-time, in-situ measurements of oxygen transfer efficiency (OTE), which is useful for: checking the condition of the diffusers, establishing cleaning intervals, determining cleaning effectiveness, and monitoring fouling rates.
- Understand the benefits and limitations of off-gas testing.
- Recognize when diffusers should be cleaned.
- Gain insights on wastewater characteristics which affect aeration cost.
