Wastewater Flow given Recirculation Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Waste Water Flow = Recirculation Flow/Recirculation Ratio
W_w = Q_r/α
This formula uses 3 Variables

Variables Used

Waste Water Flow - (Measured in Cubic Meter per Second) - Waste Water Flow refers to the movement of water and dissolved waste materials from residential, commercial, industrial, agricultural sources through a sewer system to a treatment facility.
Recirculation Flow - (Measured in Cubic Meter per Second) - Recirculation Flow refers to the portion of treated effluent that is recycled back into the treatment process.
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 Flow: 2.5 Cubic Meter per Second --> 2.5 Cubic Meter per Second No Conversion Required
Recirculation Ratio: 1.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_w = Q_r/α --> 2.5/1.5

Evaluating ... ...

W_w = 1.66666666666667

STEP 3: Convert Result to Output's Unit

1.66666666666667 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

1.66666666666667 ≈ 1.666667 Cubic Meter per Second <-- Waste Water Flow
