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
Theoretical Oxygen Requirement: 2.5 Milligram per Day --> 2.89351851851852E-11 Kilogram per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_x = ((Q_a*8.34*(S_o-S))/(f*1.42))-(O₂/1.42) --> ((1.38888888888889E-05*8.34*(0.025-0.015))/(0.68*1.42))-(2.89351851851852E-11/1.42)

Evaluating ... ...

P_x = 1.19957918124214E-06

STEP 3: Convert Result to Output's Unit

1.19957918124214E-06 Kilogram per Second -->103643.641259321 Milligram per Day (Check conversion here)

FINAL ANSWER

103643.641259321 ≈ 103643.6 Milligram per Day <-- Net Waste Activated Sludge
