The organic loading to a trickle filter is expressed as?

lbs BOD/hr/1,000ft³
lbs TSS/day/1,000ft³
lbs COD/day/1,000ft³
lbs BOD/day/1,000ft³

The correct answer is: lbs BOD/day/1,000ft³

The organic loading for a trickle filter is typically measured in pounds of BOD (biochemical oxygen demand) per day per 1,000 cubic feet (ft³) of filter media. BOD is the amount of oxygen consumed by bacteria while decomposing organic matter and is a common measure of the strength of organic pollutants in wastewater. Therefore, options A, B, and C are incorrect because they all involve measures other than BOD and do not include a daily quantity. Option D, on the other hand, is the correct expression for the organic loading to a trickle filter.
