Hydraulic Retention Time given Food to Microorganism Ratio Solution

Follow our step by step solution on how to calculate Hydraulic Retention Time given Food to Microorganism Ratio?

FIRST Step Consider the formula

θ s = \frac{FM}{S h \cdot X h}

Next Step Substitute values of Variables

∴

θ s = \frac{0.2d⁻¹}{50mg/L \cdot 0.0065mg/L}

Next Step Convert Units

∴

θ s = \frac{2.3E-6s⁻¹}{0.05kg/m³ \cdot 6.5E-6kg/m³}

Next Step Prepare to Evaluate

∴

θ s = \frac{2.3E-6}{0.05 \cdot 6.5E-6}

Next Step Evaluate

∴

θ s = 7.12250712250711s

LAST Step Rounding Answer

∴

θ s = 7.1225s
