Mixed Liquor Suspended Solids in Aeration Tank using Maximum Solids Solution

Follow our step by step solution on how to calculate Mixed Liquor Suspended Solids in Aeration Tank using Maximum Solids?

FIRST Step Consider the formula

X = (\frac{S a}{(Q p + RAS) \cdot 8.34})

Next Step Substitute values of Variables

∴

X = (\frac{38kg/s}{(37.5MLD + 10m³/d) \cdot 8.34})

Next Step Convert Units

∴

X = (\frac{38kg/s}{(0.434m³/s + 0.0001m³/s) \cdot 8.34})

Next Step Prepare to Evaluate

∴

X = (\frac{38}{(0.434 + 0.0001) \cdot 8.34})

Next Step Evaluate

∴

X = 10.4950430484724kg/m³

Next Step Convert to Output's Unit

∴

X = 10495.0430484724mg/L

LAST Step Rounding Answer

∴

X = 10495.043mg/L
