Microbial Mass in Aeration System given MLSS Solution

STEP 0: Pre-Calculation Summary
Formula Used
Total Microbial Mass = Daily bod/((Sewage Flow*Influent BOD)/(Volume of Tank*MLSS))
Mt = BOD/((Q*Qi)/(V*X))
This formula uses 6 Variables
Variables Used
Total Microbial Mass - (Measured in Kilogram) - Total microbial mass in the system in grams.
Daily bod - (Measured in Kilogram) - Daily bod load applied to the aeration 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.
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
Daily bod: 3 Milligram --> 3E-06 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
Mt = BOD/((Q*Qi)/(V*X)) --> 3E-06/((20*0.0112)/(9*1.2))
Evaluating ... ...
Mt = 0.000144642857142857
STEP 3: Convert Result to Output's Unit
0.000144642857142857 Kilogram -->0.144642857142857 Gram (Check conversion here)
FINAL ANSWER
0.144642857142857 0.144643 Gram <-- Total Microbial Mass
