Specific Substrate Utilisation Rate Per Day Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Substrate Utilisation Rate = (Sewage Discharge*(Influent BOD-Effluent BOD))/(Volume of Tank*MLSS)
U = (Q_s*(Q_i-Q_o))/(V*X)
This formula uses 6 Variables

Variables Used

Specific Substrate Utilisation Rate - (Measured in 1 Per Second) - Specific Substrate Utilisation Rate is related to the specific growth rate.
Sewage Discharge - (Measured in Cubic Meter per Second) - Sewage discharge is the flow rate of sewage when it is being discharged in the river.
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Effluent BOD - (Measured in Kilogram per Cubic Meter) - Effluent BOD is the amount of BOD present in the outing sewage.
Volume of Tank - (Measured in Cubic Meter) - Volume of tank is defined as the capacity of flocculation and mixing tank.
MLSS - (Measured in Kilogram per Cubic Meter) - MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).

STEP 1: Convert Input(s) to Base Unit

Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
Influent BOD: 11.2 Milligram per Liter --> 0.0112 Kilogram per Cubic Meter (Check conversion here)
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)
Volume of Tank: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required
MLSS: 1200 Milligram per Liter --> 1.2 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U = (Q_s*(Q_i-Q_o))/(V*X) --> (10*(0.0112-0.0004))/(9*1.2)

Evaluating ... ...

U = 0.01

STEP 3: Convert Result to Output's Unit

0.01 1 Per Second --> No Conversion Required

FINAL ANSWER

0.01 1 Per Second <-- Specific Substrate Utilisation Rate

(Calculation completed in 00.004 seconds)
