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_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 refers to the volume of liquid (feedstock) that is added to the digester per unit of time and surface area.
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 refers to the movement of water and dissolved waste materials from residential, commercial, industrial, agricultural sources through a sewer system to a treatment facility.

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: 1.4 Cubic Meter per Second --> 1.4 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = ((H*A*1440)/W_w)-1 --> ((4.62962962962963E-05*50*1440)/1.4)-1

Evaluating ... ...

α = 1.38095238095238

STEP 3: Convert Result to Output's Unit

1.38095238095238 --> No Conversion Required

FINAL ANSWER

1.38095238095238 ≈ 1.380952 <-- Recirculation Ratio

What is Hydraulic Loading?

Hydraulic Loading is defined as the wastewater treatment process unit as the volume of wastewater applied to the surface of the process unit per time period. It is often expressed in gallons per day per square foot (gpd/ft2).

How to Calculate Recirculation Ratio given Hydraulic Loading?

Recirculation Ratio given Hydraulic Loading calculator uses Recirculation Ratio = ((Hydraulic Loading*Area*1440)/Waste Water Flow)-1 to calculate the Recirculation Ratio, The Recirculation Ratio given Hydraulic Loading formula is defined as the ratio of recirculated flow to the total flow of raw sewage. The capacity of the pumps doing the recirculation of sewage is determined with this. Recirculation Ratio is denoted by α symbol.

How to calculate Recirculation Ratio given Hydraulic Loading using this online calculator? To use this online calculator for Recirculation Ratio given Hydraulic Loading, enter Hydraulic Loading (H), Area (A) & Waste Water Flow (W_w) and hit the calculate button. Here is how the Recirculation Ratio given Hydraulic Loading calculation can be explained with given input values -> 1.380952 = ((4.62962962962963E-05*50*1440)/1.4)-1.

FAQ

What is Recirculation Ratio given Hydraulic Loading?
