Concentration of Solids in Returned Sludge Solution

Follow our step by step solution on how to calculate Concentration of Solids in Returned Sludge?

FIRST Step Consider the formula

X R = \frac{M s}{Q w}

Next Step Substitute values of Variables

∴

X R = \frac{5000mg}{9.5m³/s}

Next Step Convert Units

∴

X R = \frac{0.005kg}{9.5m³/s}

Next Step Prepare to Evaluate

∴

X R = \frac{0.005}{9.5}

Next Step Evaluate

∴

X R = 0.000526315789473684kg/m³

Next Step Convert to Output's Unit

∴

X R = 0.526315789473684mg/L

LAST Step Rounding Answer

∴

X R = 0.5263mg/L
