Effluent Flow Rate - (Measured in Cubic Meter per Second) - Effluent Flow Rate is the total quantity of the flow of sewage from the secondary clarifier.
Solid Concentration in Effluent - (Measured in Kilogram per Cubic Meter) - Solid Concentration in Effluent is the total amount of solids that are present in the effluent.

STEP 1: Convert Input(s) to Base Unit

Reactor Volume: 1000 Cubic Meter --> 1000 Cubic Meter No Conversion Required
MLSS: 1200 Milligram per Liter --> 1.2 Kilogram per Cubic Meter (Check conversion here)
Mean Cell Residence Time: 7 Day --> 604800 Second (Check conversion here)
Sludge Concentration in Return Line: 200 Milligram per Liter --> 0.2 Kilogram per Cubic Meter (Check conversion here)
Effluent Flow Rate: 1523.81 Cubic Meter per Day --> 0.0176366898148148 Cubic Meter per Second (Check conversion here)
Solid Concentration in Effluent: 60 Milligram per Liter --> 0.06 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_w = (V*X/(θ_c*X_r))-(Q_e*X_e/X_r) --> (1000*1.2/(604800*0.2))-(0.0176366898148148*0.06/0.2)

Evaluating ... ...

Q_w = 0.00462962797619048

STEP 3: Convert Result to Output's Unit

0.00462962797619048 Cubic Meter per Second -->399.999857142858 Cubic Meter per Day (Check conversion here)

FINAL ANSWER

399.999857142858 ≈ 399.9999 Cubic Meter per Day <-- WAS Pumping Rate from Reactor
