Here is how the Sludge Volume Index given Sewage Discharge and MLSS equation looks like.

0.5 = \frac{(\frac{15}{10})}{(\frac{15}{10}) \cdot 1200 + 1200}

0.5L/g = \frac{(\frac{15m³/s}{10m³/s})}{(\frac{15m³/s}{10m³/s}) \cdot 1200mg/L + 1200mg/L}

0.5 = \frac{(\frac{15}{10})}{(\frac{15}{10}) \cdot 1200 + 1200}

Sludge Volume Index given Sewage Discharge and MLSS Solution

Follow our step by step solution on how to calculate Sludge Volume Index given Sewage Discharge and MLSS?

FIRST Step Consider the formula

SVI s = \frac{(\frac{Q r}{Q s})}{(\frac{Q r}{Q s}) \cdot X + X}

Next Step Substitute values of Variables

∴

SVI s = \frac{(\frac{15m³/s}{10m³/s})}{(\frac{15m³/s}{10m³/s}) \cdot 1200mg/L + 1200mg/L}

Next Step Convert Units

∴

SVI s = \frac{(\frac{15m³/s}{10m³/s})}{(\frac{15m³/s}{10m³/s}) \cdot 1.2kg/m³ + 1.2kg/m³}

Next Step Prepare to Evaluate

∴

SVI s = \frac{(\frac{15}{10})}{(\frac{15}{10}) \cdot 1.2 + 1.2}

Next Step Evaluate

∴

SVI s = 0.5m³/kg

LAST Step Convert to Output's Unit

∴

SVI s = 0.5L/g
