STEP 1: Convert Input(s) to Base Unit

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)
Oxygen Required: 0.16 Milligram per Day --> 1.85185185185185E-12 Kilogram per Second (Check conversion here)
Oxygen Demand of Biomass: 2.02 --> No Conversion Required
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)
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)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_od = (((BOD5/BOD^u)*(O_r+(D^O2*Q_w*X^R)))/(Q_i-Q)) --> (((0.00136/0.002)*(1.85185185185185E-12+(2.02*9.5*0.0014)))/(0.0132-0.0004))

Evaluating ... ...

Q_od = 1.42725625009838

STEP 3: Convert Result to Output's Unit

1.42725625009838 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

1.42725625009838 ≈ 1.427256 Cubic Meter per Second <-- Sewage Discharge given Oxygen Demand

What is Sewage?

Sewage, or domestic/municipal wastewater, is a type of wastewater that is produced by a community of people. It is characterized by volume or rate of flow, physical condition, chemical and toxic constituents, and its bacteriologic status (which organisms it contains and in what quantities).

How to Calculate Sewage Discharge given Oxygen Demand and Ultimate BOD Both?

Sewage Discharge given Oxygen Demand and Ultimate BOD Both calculator uses Sewage Discharge given Oxygen Demand = (((5 Days BOD/Ultimate BOD)*(Oxygen Required+(Oxygen Demand of Biomass*Volume of Wasted Sludge per day*MLSS in Returned or Wasted Sludge)))/(Influent BOD-Effluent BOD)) to calculate the Sewage Discharge given Oxygen Demand, The Sewage Discharge given Oxygen Demand and Ultimate BOD Both formula is defined as the calculation of sewage discharge when we have prior information of oxygen demand and ultimate BOD both. Sewage Discharge given Oxygen Demand is denoted by Q_od symbol.
