Food to Microorganism Ratio given MLSS Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables 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.
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.
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
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.
Volume of Tank - (Measured in Cubic Meter) - Volume of Tank is defined as the capacity of flocculation and mixing tank.

STEP 1: Convert Input(s) to Base Unit

Sewage Flow: 3.33 Cubic Meter --> 3.33 Cubic Meter No Conversion Required
Influent BOD: 0.0009 Milligram per Liter --> 9E-07 Kilogram per Cubic Meter (Check conversion here)
MLSS: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
Volume of Tank: 1.5 Cubic Meter --> 1.5 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FM = (Q*Q_i)/(X*V) --> (3.33*9E-07)/(0.002*1.5)

Evaluating ... ...

FM = 0.000999

STEP 3: Convert Result to Output's Unit

0.000999 --> No Conversion Required

FINAL ANSWER

0.000999 <-- Food to Microorganism Ratio

(Calculation completed in 00.004 seconds)
