Recirculation Ratio of Wastewater Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Recirculation Ratio - Recirculation Ratio is the ratio of the RAS pumping rate to influent flow rate.
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.
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

Recirculation Flow: 2.5 Cubic Meter per Second --> 2.5 Cubic Meter per Second 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 = Q_r/W_w --> 2.5/1.4

Evaluating ... ...

α = 1.78571428571429

STEP 3: Convert Result to Output's Unit

1.78571428571429 --> No Conversion Required

FINAL ANSWER

1.78571428571429 ≈ 1.785714 <-- Recirculation Ratio

What is Recirculation Ratio?

Recirculation Ratio refers to the proportion of effluent that is recycled back into the system relative to the total influent flow. The recirculation ratio can influence the overall efficiency, stability, and performance of the treatment process.

How to Calculate Recirculation Ratio of Wastewater?

Recirculation Ratio of Wastewater calculator uses Recirculation Ratio = Recirculation Flow/Waste Water Flow to calculate the Recirculation Ratio, The Recirculation Ratio of Wastewater formula is defined as the amount of wastewater that flows through the advanced pretreatment component divided by the amount of wastewater that is sent to the final treatment and dispersal component. Recirculation Ratio is denoted by α symbol.

How to calculate Recirculation Ratio of Wastewater using this online calculator? To use this online calculator for Recirculation Ratio of Wastewater, enter Recirculation Flow (Q_r) & Waste Water Flow (W_w) and hit the calculate button. Here is how the Recirculation Ratio of Wastewater calculation can be explained with given input values -> 1.785714 = 2.5/1.4.

FAQ

What is Recirculation Ratio of Wastewater?

The Recirculation Ratio of Wastewater formula is defined as the amount of wastewater that flows through the advanced pretreatment component divided by the amount of wastewater that is sent to the final treatment and dispersal component and is represented as α = Q_r/W_w or Recirculation Ratio = Recirculation Flow/Waste Water Flow. Recirculation Flow refers to the portion of treated effluent that is recycled back into the treatment process & 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.

How to calculate Recirculation Ratio of Wastewater?
