STEP 1: Convert Input(s) to Base Unit

Ratio of BOD to Ultimate BOD: 3 --> No Conversion Required
Theoretical Oxygen Requirement: 2.5 Milligram per Day --> 2.89351851851852E-11 Kilogram per Second (Check conversion here)
Oxygen Demand of Biomass: 2.02 --> No Conversion Required
Volume of Wasted Sludge per day: 9.5 Cubic Meter per Second --> 9.5 Cubic Meter per Second No Conversion Required
MLSS in Returned or Wasted Sludge: 1.4 Milligram per Liter --> 0.0014 Kilogram per Cubic Meter (Check conversion here)
Influent BOD: 13.2 Milligram per Liter --> 0.0132 Kilogram per Cubic Meter (Check conversion here)
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_sb = ((f*(O₂+(D^O2*Q_w*X^R)))/(Q_i-Q)) --> ((3*(2.89351851851852E-11+(2.02*9.5*0.0014)))/(0.0132-0.0004))

Evaluating ... ...

Q_sb = 6.29671875678168

STEP 3: Convert Result to Output's Unit

6.29671875678168 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

6.29671875678168 ≈ 6.296719 Cubic Meter per Second <-- Sewage Discharge given Oxygen Demand of Biomass
