Sludge Concentration using Wasting Rate from Return Line when Solid Concentration in Effluent is Low Solution

Follow our step by step solution on how to calculate Sludge Concentration using Wasting Rate from Return Line when Solid Concentration in Effluent is Low?

FIRST Step Consider the formula

X r = V \cdot \frac{X}{θ m \cdot Q w'}

Next Step Substitute values of Variables

∴

X r = 1000m³ \cdot \frac{1200mg/L}{14d \cdot 400m³/d}

Next Step Convert Units

∴

X r = 1000m³ \cdot \frac{1.2kg/m³}{1.2E+6s \cdot 0.0046m³/s}

Next Step Prepare to Evaluate

∴

X r = 1000 \cdot \frac{1.2}{1.2E+6 \cdot 0.0046}

Next Step Evaluate

∴

X r = 0.214285714285714kg/m³

Next Step Convert to Output's Unit

∴

X r = 214.285714285714mg/L

LAST Step Rounding Answer

∴

X r = 214.2857mg/L
