MLSS given SVI and Sewage Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mixed Liquor Suspended Solids = (((Recirculation Flow given MLSS/Sewage Discharge given MLSS)*(10^6))/Sludge Volume Index)/(1+(Recirculation Flow given MLSS/Sewage Discharge given MLSS))
X^' = (((Q_r''/Qs')*(10^6))/SVI)/(1+(Q_r''/Qs'))
This formula uses 4 Variables

Variables Used

Mixed Liquor Suspended Solids - (Measured in Kilogram per Cubic Meter) - Mixed Liquor Suspended Solids refers to the concentration of suspended solids in the mixed liquor of an aeration tank during the activated sludge process.
Recirculation Flow given MLSS - (Measured in Cubic Meter per Second) - Recirculation Flow given MLSS is the flow generated in recirculation tank collecting the primary treated effluent from a pretreatment component, considering MLSS.
Sewage Discharge given MLSS - (Measured in Cubic Meter per Second) - Sewage Discharge given MLSS is the sewage inflow rate considering MLSS.
Sludge Volume Index - (Measured in Cubic Meter per Kilogram) - Sludge Volume Index is the volume occupied by 1 gram of activated sludge after 30 minutes of settling in a 1-liter graduated cylinder. SVI is expressed in milliliters per gram.

STEP 1: Convert Input(s) to Base Unit

Recirculation Flow given MLSS: 100 Cubic Meter per Day --> 0.00115740740740741 Cubic Meter per Second (Check conversion here)
Sewage Discharge given MLSS: 9000 Cubic Meter per Second --> 9000 Cubic Meter per Second No Conversion Required
Sludge Volume Index: 150 Milliliter per Gram --> 0.15 Cubic Meter per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

X^' = (((Q_r''/Qs')*(10^6))/SVI)/(1+(Q_r''/Qs')) --> (((0.00115740740740741/9000)*(10^6))/0.15)/(1+(0.00115740740740741/9000))

Evaluating ... ...

X^' = 0.857338710047321

STEP 3: Convert Result to Output's Unit

0.857338710047321 Kilogram per Cubic Meter -->857.338710047321 Milligram per Liter (Check conversion here)

FINAL ANSWER

857.338710047321 ≈ 857.3387 Milligram per Liter <-- Mixed Liquor Suspended Solids

(Calculation completed in 00.020 seconds)
