STEP 1: Convert Input(s) to Base Unit

Ultimate BOD: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
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)
Theoretical Oxygen Requirement: 2.5 Milligram per Day --> 2.89351851851852E-11 Kilogram per Second (Check conversion here)
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)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BOD_5a = BOD^u*(Q_s*(Q_i-Q))/(O₂+(1.42*Q_w*X^R)) --> 0.002*(10*(0.0132-0.0004))/(2.89351851851852E-11+(1.42*9.5*0.0014))

Evaluating ... ...

BOD_5a = 0.0135550142755365

STEP 3: Convert Result to Output's Unit

0.0135550142755365 Kilogram per Cubic Meter -->13.5550142755365 Milligram per Liter (Check conversion here)

FINAL ANSWER

13.5550142755365 ≈ 13.55501 Milligram per Liter <-- BOD5 given Oxygen Required in Aeration Tank
