Effluent Substrate Concentration given Theoretical Oxygen Requirement Solution

Follow our step by step solution on how to calculate Effluent Substrate Concentration given Theoretical Oxygen Requirement?

FIRST Step Consider the formula

S = S o - ((O 2 + (1.42 \cdot P x)) \cdot (\frac{f}{8.34 \cdot Q a}))

Next Step Substitute values of Variables

∴

S = 25mg/L - ((2.5mg/d + (1.42 \cdot 20mg/d)) \cdot (\frac{0.68}{8.34 \cdot 1.2m³/d}))

Next Step Convert Units

∴

S = 0.025kg/m³ - ((2.9E-11kg/s + (1.42 \cdot 2.3E-10kg/s)) \cdot (\frac{0.68}{8.34 \cdot 1.4E-5m³/s}))

Next Step Prepare to Evaluate

∴

S = 0.025 - ((2.9E-11 + (1.42 \cdot 2.3E-10)) \cdot (\frac{0.68}{8.34 \cdot 1.4E-5}))

Next Step Evaluate

∴

S = 0.0249979004796163kg/m³

Next Step Convert to Output's Unit

∴

S = 24.9979004796163mg/L

LAST Step Rounding Answer

∴

S = 24.9979mg/L
