Surface Aerator Oxygen Transfer Rate
This app guides operators through the complete SOTR test workflow for surface aerators. Calculate KLa(T), KLa(20°C), and SOTR (kg O₂/hr) with predictive margin of error (95% CI).
Important Notes
- No chemical deoxygenation — sodium sulfite or metabisulfite is not used
- Starts from actual conditions — test begins from the current tank DO and temperature
- Results are displayed as Estimated SOTR (non-deoxygenated start)
