Sewage Flow given Food to Microorganism Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sewage Flow = (Food to Microorganism Ratio*Volume of Tank*MLSS)/Influent BOD
Q = (FM*V*X)/Q_i
This formula uses 5 Variables

Variables Used

Sewage Flow - (Measured in Cubic Meter) - Sewage Flow into the aeration tank is the sewage flow into the aeration tank when we have prior information of other parameters used.
Food to Microorganism Ratio - Food to Microorganism Ratio is actually a measurement of the amount of incoming food divided by the Lbs of Microorganisms in your system.
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 concentration of suspended solids in the mixed liquor within an aeration tank during the activated sludge process.
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.

STEP 1: Convert Input(s) to Base Unit

Food to Microorganism Ratio: 0.001 --> No Conversion Required
Volume of Tank: 1.5 Cubic Meter --> 1.5 Cubic Meter No Conversion Required
MLSS: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
Influent BOD: 0.0009 Milligram per Liter --> 9E-07 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = (FM*V*X)/Q_i --> (0.001*1.5*0.002)/9E-07

Evaluating ... ...

Q = 3.33333333333333

STEP 3: Convert Result to Output's Unit

3.33333333333333 Cubic Meter --> No Conversion Required

FINAL ANSWER

3.33333333333333 ≈ 3.333333 Cubic Meter <-- Sewage Flow
