What is the recirculation ratio for a trickling filter?

Qr/Q
Q/Qt
Qr/Qt
Qr/Qe

The correct answer is: Qr/Q

The recirculation ratio for a trickling filter refers to the ratio of the recirculation flow rate (Qr) to the influent flow rate (Q). This is because recirculation flow is crucial in maintaining the proper operation of a trickling filter. It helps to distribute and evenly disperse the influent and bacterial growth over the filter media. Therefore, option A (Qr/Q) is the most accurate choice. Options B, C, and D are incorrect because they either refer to the influent flow rate (Q) instead of the recirculation flow rate (Qr), or they reference the effluent flow rate (Qe) instead of the influent flow rate (Q).
