Biological Oxygen Demand influent Solution

STEP 0: Pre-Calculation Summary
Formula Used
Biological oxygen demand = (Food to microorganism ratio*Volume of Tank*MLSS)/Sewage Flow
BODi = (FM*V*X)/Q
This formula uses 5 Variables
Variables Used
Biological oxygen demand - (Measured in Kilogram per Cubic Meter) - Biological Oxygen Demand is applied to determine the aerobic destructibility of organic substances.
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.
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).
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
Food to microorganism ratio: 0.8 --> No Conversion Required
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)
Sewage Flow: 20 Cubic Meter --> 20 Cubic Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
BODi = (FM*V*X)/Q --> (0.8*9*1.2)/20
Evaluating ... ...
BODi = 0.432
STEP 3: Convert Result to Output's Unit
0.432 Kilogram per Cubic Meter -->432 Milligram per Liter (Check conversion here)
FINAL ANSWER
432 Milligram per Liter <-- Biological oxygen demand
(Calculation completed in 00.004 seconds)
