Effluent BOD given Mass of Wasted Activated Sludge Solution

Follow our step by step solution on how to calculate Effluent BOD given Mass of Wasted Activated Sludge?

FIRST Step Consider the formula

Q o = Q i - (\frac{M ws + (K e \cdot V \cdot X')}{Y \cdot Q s})

Next Step Substitute values of Variables

∴

Q o = 11.2mg/L - (\frac{53626mg + (2.99d⁻¹ \cdot 9m³ \cdot 1200mg/L)}{0.5 \cdot 10m³/s})

Next Step Convert Units

∴

Q o = 0.0112kg/m³ - (\frac{0.0536kg + (3.5E-5s⁻¹ \cdot 9m³ \cdot 1.2kg/m³)}{0.5 \cdot 10m³/s})

Next Step Prepare to Evaluate

∴

Q o = 0.0112 - (\frac{0.0536 + (3.5E-5 \cdot 9 \cdot 1.2)}{0.5 \cdot 10})

Next Step Evaluate

∴

Q o = 0.000400050000000001kg/m³

Next Step Convert to Output's Unit

∴

Q o = 0.400050000000001mg/L

LAST Step Rounding Answer

∴

Q o = 0.4001mg/L
