Tanque de aeração: oxigênio a fornecer (ABNT 12209)
Without nitrification
With nitrification
For UASB
Input data
Concentration of BOD
Upstream flow
Output data
Oxygen mass
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).
