STEP 1: Convert Input(s) to Base Unit

Influent BOD: 13.2 Milligram per Liter --> 0.0132 Kilogram per Cubic Meter (Check conversion here)
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)
Sewage Flowrate: 15 Cubic Meter per Second --> 15 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_b = Q_i-((f*(O₂+(D^O2*Q_w*X^R)))/SF) --> 0.0132-((3*(2.89351851851852E-11+(2.02*9.5*0.0014)))/15)

Evaluating ... ...

Q_b = 0.00782679999421296

STEP 3: Convert Result to Output's Unit

0.00782679999421296 Kilogram per Cubic Meter -->7.82679999421296 Milligram per Liter (Check conversion here)

FINAL ANSWER

7.82679999421296 ≈ 7.8268 Milligram per Liter <-- Effluent BOD given Oxygen Demand of Biomass
