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

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

FIRST Step Consider the formula

X' = θ c \cdot Q \cdot \frac{X r}{V}

Next Step Substitute values of Variables

∴

X' = 7d \cdot 300m³/d \cdot \frac{200mg/L}{1000m³}

Next Step Convert Units

∴

X' = 604800s \cdot 0.0035m³/s \cdot \frac{0.2kg/m³}{1000m³}

Next Step Prepare to Evaluate

∴

X' = 604800 \cdot 0.0035 \cdot \frac{0.2}{1000}

Next Step Evaluate

∴

X' = 0.42kg/m³

LAST Step Convert to Output's Unit

∴

X' = 420mg/L
