BOD Influent given MLSS Solution

STEP 0: Pre-Calculation Summary

Formula Used

Influent BOD = (Daily BOD*MLSS*Volume of Tank)/(Total Microbial Mass*Sewage Flow)
Q_i = (BOD*X*V)/(M_t*Q)
This formula uses 6 Variables

Variables Used

Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Daily BOD - (Measured in Kilogram) - Daily BOD load measures the amount of oxygen that microorganisms will consume while decomposing organic matter in a water sample over a 24-hour period.
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.
Total Microbial Mass - (Measured in Kilogram) - Total Microbial Mass is the cumulative mass of microorganisms present in a given sample or system. This includes bacteria, fungi, protozoa, and other microbes.
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.

STEP 1: Convert Input(s) to Base Unit

Daily BOD: 3 Milligram --> 3E-06 Kilogram (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
Total Microbial Mass: 3 Gram --> 0.003 Kilogram (Check conversion here)
Sewage Flow: 3.33 Cubic Meter --> 3.33 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_i = (BOD*X*V)/(M_t*Q) --> (3E-06*0.002*1.5)/(0.003*3.33)

Evaluating ... ...

Q_i = 9.00900900900901E-07

STEP 3: Convert Result to Output's Unit

9.00900900900901E-07 Kilogram per Cubic Meter -->0.000900900900900901 Milligram per Liter (Check conversion here)

FINAL ANSWER

0.000900900900900901 ≈ 0.000901 Milligram per Liter <-- Influent BOD
