Specific Substrate Utilization Rate Per Day Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Substrate Utilization Rate Per Day = (Sewage Discharge*(Influent BOD-Effluent BOD))/(Volume of Tank*Mixed Liquor Suspended Solids)
U' = (Q_s*(Q_i-Q_o))/(V*X^')
This formula uses 6 Variables

Variables Used

Specific Substrate Utilization Rate Per Day - (Measured in 1 Per Second) - Specific Substrate Utilization Rate Per Day is the rate at which a specific substrate is utilized by microorganisms within a treatment system, expressed on a per-day basis.
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.
Mixed Liquor Suspended Solids - (Measured in Kilogram per Cubic Meter) - Mixed Liquor Suspended Solids is the concentration of suspended solids in the mixed liquor of an aeration tank during the activated sludge process.

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
Mixed Liquor Suspended Solids: 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 Utilization Rate Per Day

(Calculation completed in 00.004 seconds)
