Oxygen Required in Aeration Tank given Ultimate BOD Solution

STEP 0: Pre-Calculation Summary

Formula Used

Oxygen Required = ((Sewage Discharge*(Influent BOD-Effluent BOD))/(5 Days BOD/Ultimate BOD))-(1.42*Volume of Wasted Sludge per day*MLSS in Returned or Wasted Sludge)
O_r = ((Q_s*(Q_i-Q))/(BOD5/BOD^u))-(1.42*Q_w*X^R)
This formula uses 8 Variables

Variables Used

Oxygen Required - (Measured in Milligram per Day) - Oxygen Required is the amount of oxygen needed to sustain biological processes in an aeration tank, which is a critical component of wastewater treatment systems.
Sewage Discharge - (Measured in Cubic Meter per Second) - Sewage Discharge is the flow rate of sewage when it is being discharged in the river.
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Effluent BOD - (Measured in Kilogram per Cubic Meter) - Effluent BOD is the amount of BOD present in the outing sewage.
5 Days BOD - (Measured in Kilogram per Cubic Meter) - 5 Days BOD is an indicator of how much oxygen is utilized by a natural water sample in five days at 20 degrees C.
Ultimate BOD - (Measured in Kilogram per Cubic Meter) - Ultimate BOD is the amount of oxygen required to decompose all of the organic material after infinite time.
Volume of Wasted Sludge per day - (Measured in Cubic Meter per Second) - Volume of Wasted Sludge per day is the amount of sludge that is removed or wasted from a wastewater treatment process on a daily basis.
MLSS in Returned or Wasted Sludge - (Measured in Kilogram per Cubic Meter) - MLSS in Returned or Wasted Sludge is the mixed liquor suspended solids in returned sludge in terms of mg per liter.

STEP 1: Convert Input(s) to Base Unit

Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
Influent BOD: 13.2 Milligram per Liter --> 0.0132 Kilogram per Cubic Meter (Check conversion here)
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)
5 Days BOD: 1.36 Milligram per Liter --> 0.00136 Kilogram per Cubic Meter (Check conversion here)
Ultimate BOD: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
Volume of Wasted Sludge per day: 9.5 Cubic Meter per Second --> 9.5 Cubic Meter per Second No Conversion Required
MLSS in Returned or Wasted Sludge: 1.4 Milligram per Liter --> 0.0014 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

O_r = ((Q_s*(Q_i-Q))/(BOD5/BOD^u))-(1.42*Q_w*X^R) --> ((10*(0.0132-0.0004))/(0.00136/0.002))-(1.42*9.5*0.0014)

Evaluating ... ...

O_r = 0.169349294117647

STEP 3: Convert Result to Output's Unit

1.9600612745098E-12 Kilogram per Second -->0.169349294117647 Milligram per Day (Check conversion here)

FINAL ANSWER

0.169349294117647 ≈ 0.169349 Milligram per Day <-- Oxygen Required

What is Aeration Tank?

Aeration tank where air (or oxygen) is injected in the mixed liquor. Settling tank (usually referred to as "final clarifier" or "secondary settling tank") to allow the biological flocs (the sludge blanket) to settle, thus separating the biological sludge from the clear treated water.

How to Calculate Oxygen Required in Aeration Tank given Ultimate BOD?

Oxygen Required in Aeration Tank given Ultimate BOD calculator uses Oxygen Required = ((Sewage Discharge*(Influent BOD-Effluent BOD))/(5 Days BOD/Ultimate BOD))-(1.42*Volume of Wasted Sludge per day*MLSS in Returned or Wasted Sludge) to calculate the Oxygen Required, The Oxygen Required in Aeration Tank given Ultimate BOD formula is defined as the calculation of oxygen required in aeration tank when we have prior information of Ultimate BOD. Oxygen Required is denoted by O_r symbol.

How to calculate Oxygen Required in Aeration Tank given Ultimate BOD using this online calculator?
