Mixed Liquor Suspended Solids given Sludge Age Solution

Follow our step by step solution on how to calculate Mixed Liquor Suspended Solids given Sludge Age?

FIRST Step Consider the formula

X' = \frac{Q w \cdot X Em \cdot θ c}{V}

Next Step Substitute values of Variables

∴

X' = \frac{9.5m³/s \cdot 0.0026mg/L \cdot 5d}{9m³}

Next Step Convert Units

∴

X' = \frac{9.5m³/s \cdot 2.6E-6kg/m³ \cdot 432000s}{9m³}

Next Step Prepare to Evaluate

∴

X' = \frac{9.5 \cdot 2.6E-6 \cdot 432000}{9}

Next Step Evaluate

∴

X' = 1.1856kg/m³

LAST Step Convert to Output's Unit

∴

X' = 1185.6mg/L
