Recirculation Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Recirculation Factor = (1+Recirculation Ratio)/((1+Recirculation Ratio/10)^2)
F = (1+α)/((1+α/10)^2)
This formula uses 2 Variables

Variables Used

Recirculation Factor - Recirculation Factor refers to the average number of passes of the influent organic matter through the trickling filter.
Recirculation Ratio - Recirculation Ratio is the ratio of the RAS pumping rate to influent flow rate.

STEP 1: Convert Input(s) to Base Unit

Recirculation Ratio: 1.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = (1+α)/((1+α/10)^2) --> (1+1.5)/((1+1.5/10)^2)

Evaluating ... ...

F = 1.89035916824197

STEP 3: Convert Result to Output's Unit

1.89035916824197 --> No Conversion Required

FINAL ANSWER

1.89035916824197 ≈ 1.890359 <-- Recirculation Factor
