STEP 1: Convert Input(s) to Base Unit

Average daily influent flow rate: 1.2 Cubic Meter per Day --> 1.38888888888889E-05 Cubic Meter per Second (Check conversion here)
Influent Substrate Concentration: 25 Milligram per Liter --> 0.025 Kilogram per Cubic Meter (Check conversion here)
Effluent substrate concentration: 15 Milligram per Liter --> 0.015 Kilogram per Cubic Meter (Check conversion here)
BOD conversion factor: 0.68 --> No Conversion Required
Net waste activated sludge: 20 Milligram per Day --> 2.31481481481481E-10 Kilogram per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

O₂ = ((Q*(S_o-S)*8.34)/f)-(1.42*P_x) --> ((1.38888888888889E-05*(0.025-0.015)*8.34)/0.68)-(1.42*2.31481481481481E-10)

Evaluating ... ...

O₂ = 1.70310266884532E-06

STEP 3: Convert Result to Output's Unit

1.70310266884532E-06 Kilogram per Second -->147148.070588235 Milligram per Day (Check conversion here)

FINAL ANSWER

147148.070588235 ≈ 147148.1 Milligram per Day <-- Theoretical Oxygen Requirement

Theoretical Oxygen requirements using Conversion Factor

Go Theoretical Oxygen Requirement = ((Average daily influent flow rate*(Influent Substrate Concentration-Effluent substrate concentration)*8.34)/BOD conversion factor)-(1.42*Net waste activated sludge)

Conversion Factor given Theoretical Oxygen Requirement

Go BOD conversion factor = (8.34*Average daily influent flow rate*(Influent Substrate Concentration-Effluent substrate concentration))/(Theoretical Oxygen Requirement+(1.42*Net waste activated sludge))

Theoretical Oxygen Requirement for removal of Carbonaceous Organic Matter

Go Theoretical Oxygen Requirement = Total BOD Utilized-(1.42*Mass of Organisms Wasted)

Total Mass of BOD Utilized given Theoretical Oxygen Requirement

Go Total BOD Utilized = Theoretical Oxygen Requirement+(1.42*Mass of Organisms Wasted)

Mass of Organisms Wasted given Theoretical Oxygen Requirement

Go Mass of Organisms Wasted = (Total BOD Utilized-Theoretical Oxygen Requirement)/1.42
