Influent BOD given Substrate Utilization Rate - (Measured in Kilogram per Cubic Meter) - Influent BOD given Substrate Utilization Rate is the measure of the organic load entering a wastewater treatment system based on the rate at which microorganisms consume organic matter.
Specific Substrate Utilization Rate - (Measured in 1 Per Second) - Specific Substrate Utilization Rate is the rate at which a microbial population consumes a substrate per unit of biomass present.
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.
Sewage Discharge - (Measured in Cubic Meter per Second) - Sewage Discharge is the flow rate of sewage when it is being discharged in the river.
Effluent BOD - (Measured in Kilogram per Cubic Meter) - Effluent BOD is the amount of BOD present in the outing sewage.

STEP 1: Convert Input(s) to Base Unit

Specific Substrate Utilization Rate: 0.5 1 Per Second --> 0.5 1 Per Second No Conversion Required
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)
Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_i' = ((U*V*X^')/Q_s)+Q_o --> ((0.5*9*1.2)/10)+0.0004

Evaluating ... ...

Q_i' = 0.5404

STEP 3: Convert Result to Output's Unit

0.5404 Kilogram per Cubic Meter -->540.4 Milligram per Liter (Check conversion here)

FINAL ANSWER

540.4 Milligram per Liter <-- Influent BOD given Substrate Utilization Rate

(Calculation completed in 00.004 seconds)
