Effluent BOD given Mass of Wasted Activated Sludge Solution

STEP 0: Pre-Calculation Summary
Formula Used
Effluent BOD = Influent BOD-((Mass of Solids+(Endogenous Respiration Rate Constant*Volume of Tank*MLSS))/(Maximum Yield Coefficient*Sewage Discharge))
Qo = Qi-((Ms+(Ke*V*X))/(Y*Qs))
This formula uses 8 Variables
Variables Used
Effluent BOD - (Measured in Kilogram per Cubic Meter) - Effluent BOD is the amount of BOD present in the outing sewage.
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Mass of Solids - (Measured in Kilogram) - Mass of solids means the actuall weight of the solid particle present in the sewage.
Endogenous Respiration Rate Constant - (Measured in 1 Per Second) - Endogenous Respiration Rate Constant is used for designing a complete-mix activated-sludge 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).
Maximum Yield Coefficient - Maximum Yield Coefficient Y represents the maximum mg of cells produced per mg organic matter removed.
Sewage Discharge - (Measured in Cubic Meter per Second) - Sewage discharge is the flow rate of sewage when it is being discharged in the river.
STEP 1: Convert Input(s) to Base Unit
Influent BOD: 11.2 Milligram per Liter --> 0.0112 Kilogram per Cubic Meter (Check conversion here)
Mass of Solids: 5 Gram --> 0.005 Kilogram (Check conversion here)
Endogenous Respiration Rate Constant: 3 1 Per Day --> 3.47222222222222E-05 1 Per Second (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)
Maximum Yield Coefficient: 0.5 --> No Conversion Required
Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qo = Qi-((Ms+(Ke*V*X))/(Y*Qs)) --> 0.0112-((0.005+(3.47222222222222E-05*9*1.2))/(0.5*10))
Evaluating ... ...
Qo = 0.010125
STEP 3: Convert Result to Output's Unit
0.010125 Kilogram per Cubic Meter -->10.125 Milligram per Liter (Check conversion here)
FINAL ANSWER
10.125 Milligram per Liter <-- Effluent BOD
(Calculation completed in 00.019 seconds)

Effluent BOD given Mass of Wasted Activated Sludge Formula

Effluent BOD = Influent BOD-((Mass of Solids+(Endogenous Respiration Rate Constant*Volume of Tank*MLSS))/(Maximum Yield Coefficient*Sewage Discharge))
Qo = Qi-((Ms+(Ke*V*X))/(Y*Qs))

What is effluent BOD ?

BOD of wastewater effluents is used to indicate the short-term impact on the oxygen levels of the receiving water. BOD analysis is similar in function to chemical oxygen demand (COD) analysis, in that both measure the amount of organic compounds in water.

How to Calculate Effluent BOD given Mass of Wasted Activated Sludge?

Effluent BOD given Mass of Wasted Activated Sludge calculator uses Effluent BOD = Influent BOD-((Mass of Solids+(Endogenous Respiration Rate Constant*Volume of Tank*MLSS))/(Maximum Yield Coefficient*Sewage Discharge)) to calculate the Effluent BOD, Effluent BOD given Mass of Wasted Activated Sludge calculates effluent BOD when we have prior information of other parameters used. Effluent BOD is denoted by Qo symbol.

How to calculate Effluent BOD given Mass of Wasted Activated Sludge using this online calculator? To use this online calculator for Effluent BOD given Mass of Wasted Activated Sludge, enter Influent BOD (Qi), Mass of Solids (Ms), Endogenous Respiration Rate Constant (Ke), Volume of Tank (V), MLSS (X), Maximum Yield Coefficient (Y) & Sewage Discharge (Qs) and hit the calculate button. Here is how the Effluent BOD given Mass of Wasted Activated Sludge calculation can be explained with given input values -> 10125 = 0.0112-((0.005+(3.47222222222222E-05*9*1.2))/(0.5*10)).
