Volume of Wasted Sludge Per Day given Ultimate BOD Solution

Follow our step by step solution on how to calculate Volume of Wasted Sludge Per Day given Ultimate BOD?

FIRST Step Consider the formula

Q w' = \frac{(\frac{Q s \cdot (Q i - Q)}{\frac{BOD5}{BOD u}}) - O 2}{1.42 \cdot X}

Next Step Substitute values of Variables

∴

Q w' = \frac{(\frac{10m³/s \cdot (13.2mg/L - 0.4mg/L)}{\frac{1.36mg/L}{2mg/L}}) - 2.5mg/d}{1.42 \cdot 1200mg/L}

Next Step Convert Units

∴

Q w' = \frac{(\frac{10m³/s \cdot (0.0132kg/m³ - 0.0004kg/m³)}{\frac{0.0014kg/m³}{0.002kg/m³}}) - 2.9E-11kg/s}{1.42 \cdot 1.2kg/m³}

Next Step Prepare to Evaluate

∴

Q w' = \frac{(\frac{10 \cdot (0.0132 - 0.0004)}{\frac{0.0014}{0.002}}) - 2.9E-11}{1.42 \cdot 1.2}

Next Step Evaluate

∴

Q w' = 0.110466721883047m³/s

LAST Step Rounding Answer

∴

Q w' = 0.1105m³/s
