Question:medium

A trickling filter receives an organic load of \(300~\mathrm{kg\ BOD/day}\) and has a filter volume of \(150~\mathrm{m^3}\). What is the organic loading rate of the filter?

Show Hint

Organic loading rate: \[ \boxed{ \text{Organic Loading} = \frac{\text{BOD Load (kg/day)}}{\text{Filter Volume (m}^3\text{)}} } \]

Updated On: Jul 18, 2026

\(0.5~\mathrm{kg\ BOD/m^3\!\cdot\!day}\)
\(2~\mathrm{kg\ BOD/m^3\!\cdot\!day}\)
\(5~\mathrm{kg\ BOD/m^3\!\cdot\!day}\)
\(10~\mathrm{kg\ BOD/m^3\!\cdot\!day}\)

Show Solution

The Correct Option is B
