BOD Load Applied given MLSS Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Daily bod - (Measured in Kilogram) - Daily bod load applied to the aeration system.
Total Microbial Mass - (Measured in Kilogram) - Total microbial mass in the system in grams.
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.
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 sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).

STEP 1: Convert Input(s) to Base Unit

Total Microbial Mass: 3 Gram --> 0.003 Kilogram (Check conversion here)
Sewage Flow: 20 Cubic Meter --> 20 Cubic Meter No Conversion Required
Influent BOD: 11.2 Milligram per Liter --> 0.0112 Kilogram per Cubic Meter (Check conversion here)
Volume of Tank: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required
MLSS: 1200 Milligram per Liter --> 1.2 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BOD = M_t*((Q*Q_i)/(V*X)) --> 0.003*((20*0.0112)/(9*1.2))

Evaluating ... ...

BOD = 6.22222222222222E-05

STEP 3: Convert Result to Output's Unit

6.22222222222222E-05 Kilogram -->62.2222222222222 Milligram (Check conversion here)

FINAL ANSWER

62.2222222222222 ≈ 62.22222 Milligram <-- Daily bod
