Description
Given the influent flow and BOD concentration, finds the supplying mass oxygen flow. Three possibilities are available:
- The activated sludge system will not perform the sewage nitrification (without nitrification);
- The activated sludge system will perform the sewage nitrification (with nitrification);
- The activated sludge system will treat the UASB reactors effluent (for UASB).
