Recirculation Factor given Recirculation Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Recirculation Factor = (1+Recirculation Ratio)/(1+0.1*Recirculation Ratio)^2
F = (1+α)/(1+0.1*α)^2
This formula uses 2 Variables
Variables Used
Recirculation Factor - Recirculation factor r represents 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: 0.15 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
F = (1+α)/(1+0.1*α)^2 --> (1+0.15)/(1+0.1*0.15)^2
