Sewage Flow given MLSS Formula Elements

Variables
Sewage Flow
Sewage Flow into the aeration tank is the sewage flow into the aeration tank when we have prior information of other parameters used.
Symbol: Q
Measurement: VolumeUnit:
Note: Value should be greater than 0.
Daily BOD
Daily BOD load measures the amount of oxygen that microorganisms will consume while decomposing organic matter in a water sample over a 24-hour period.
Symbol: BOD
Measurement: WeightUnit: mg
Note: Value should be greater than 0.
MLSS
MLSS is the concentration of suspended solids in the mixed liquor within an aeration tank during the activated sludge process.
Symbol: X
Measurement: DensityUnit: mg/L
Note: Value should be greater than 0.
Volume of Tank
Volume of Tank is defined as the capacity of flocculation and mixing tank.
Symbol: V
Measurement: VolumeUnit:
Note: Value should be greater than 0.
Total Microbial Mass
Total Microbial Mass is the cumulative mass of microorganisms present in a given sample or system. This includes bacteria, fungi, protozoa, and other microbes.
Symbol: Mt
Measurement: WeightUnit: g
Note: Value should be greater than 0.
Influent BOD
Influent BOD is the total amount of BOD which is present in the incoming sewage.
Symbol: Qi
Measurement: DensityUnit: mg/L
Note: Value should be greater than 0.

How to Evaluate Sewage Flow given MLSS?

Sewage Flow given MLSS evaluator uses Sewage Flow = (Daily BOD*MLSS*Volume of Tank)/(Total Microbial Mass*Influent BOD) to evaluate the Sewage Flow, The Sewage Flow given MLSS formula is defined as the calculation of sewage flow when we have prior information of MLSS. Sewage Flow is denoted by Q symbol.

How to evaluate Sewage Flow given MLSS using this online evaluator? To use this online evaluator for Sewage Flow given MLSS, enter Daily BOD (BOD), MLSS (X), Volume of Tank (V), Total Microbial Mass (Mt) & Influent BOD (Qi) and hit the calculate button.

FAQs on Sewage Flow given MLSS

What is the formula to find Sewage Flow given MLSS?
The formula of Sewage Flow given MLSS is expressed as Sewage Flow = (Daily BOD*MLSS*Volume of Tank)/(Total Microbial Mass*Influent BOD). Here is an example- 20 = (3E-06*0.002*1.5)/(0.003*9E-07).
How to calculate Sewage Flow given MLSS?
With Daily BOD (BOD), MLSS (X), Volume of Tank (V), Total Microbial Mass (Mt) & Influent BOD (Qi) we can find Sewage Flow given MLSS using the formula - Sewage Flow = (Daily BOD*MLSS*Volume of Tank)/(Total Microbial Mass*Influent BOD).
What are the other ways to Calculate Sewage Flow?
Here are the different ways to Calculate Sewage Flow-
  • Sewage Flow=Daily BOD/Influent BODOpenImg
  • Sewage Flow=(Food to Microorganism Ratio*Volume of Tank*MLSS)/Influent BODOpenImg
Can the Sewage Flow given MLSS be negative?
No, the Sewage Flow given MLSS, measured in Volume cannot be negative.
Which unit is used to measure Sewage Flow given MLSS?
Sewage Flow given MLSS is usually measured using the Cubic Meter[m³] for Volume. Cubic Centimeter[m³], Cubic Millimeter[m³], Liter[m³] are the few other units in which Sewage Flow given MLSS can be measured.
