Recirculation Ratio given Hydraulic Loading Solution

STEP 0: Pre-Calculation Summary

Formula Used

Recirculation Ratio = ((Hydraulic loading*Area*1440)/Waste water flow)-1
α = ((H*A*1440)/W)-1
This formula uses 4 Variables

Variables Used

Recirculation Ratio - Recirculation Ratio is the ratio of the RAS pumping rate to influent flow rate.
Hydraulic loading - (Measured in Cubic Meter per Second) - Hydraulic loading is defined in a wastewater treatment process unit as the volume of wastewater applied to the surface of the processing unit per time period.
Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.
Waste water flow - (Measured in Cubic Meter per Second) - Waste water flow are generated from domestic, industrial, and commercial uses.

STEP 1: Convert Input(s) to Base Unit

Hydraulic loading: 4 Cubic Meter per Day --> 4.62962962962963E-05 Cubic Meter per Second (Check conversion here)
Area: 50 Square Meter --> 50 Square Meter No Conversion Required
Waste water flow: 1.5 Cubic Meter per Second --> 1.5 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = ((H*A*1440)/W)-1 --> ((4.62962962962963E-05*50*1440)/1.5)-1

Evaluating ... ...

α = 1.22222222222222

STEP 3: Convert Result to Output's Unit

1.22222222222222 --> No Conversion Required

FINAL ANSWER

1.22222222222222 ≈ 1.222222 <-- Recirculation Ratio
