Volume of Tank given Food to Microorganism Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Volume of Tank = (Sewage Flow*Influent BOD)/(Food to microorganism ratio*MLSS)
V = (Q*Qi)/(FM*X)
This formula uses 5 Variables
Variables Used
Volume of Tank - (Measured in Cubic Meter) - Volume of tank is defined as the capacity of flocculation and mixing tank.
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.
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.
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
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)
Food to microorganism ratio: 0.8 --> 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
V = (Q*Qi)/(FM*X) --> (20*0.0112)/(0.8*1.2)
Evaluating ... ...
V = 0.233333333333333
STEP 3: Convert Result to Output's Unit
0.233333333333333 Cubic Meter --> No Conversion Required
FINAL ANSWER
0.233333333333333 0.233333 Cubic Meter <-- Volume of Tank
