Influent Flow Rate given Return Activated Sludge Flow Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Average Daily Influent Flow Rate = (Return Activated Sludge/1.25)
Q = (RAS/1.25)
This formula uses 2 Variables

Variables Used

Average Daily Influent Flow Rate - (Measured in Cubic Meter per Second) - The Average Daily Influent Flow Rate is the total volume of wastewater entering a treatment facility per day, averaged over a specified period, typically measured in cubic meters per day (m³/day).
Return Activated Sludge - (Measured in Cubic Meter per Second) - Return Activated Sludge is the portion of settled biomass that is recycled from the secondary clarifier back to the aeration tank in a wastewater treatment process.

STEP 1: Convert Input(s) to Base Unit

Return Activated Sludge: 10 Cubic Meter per Day --> 0.000115740740740741 Cubic Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = (RAS/1.25) --> (0.000115740740740741/1.25)

Evaluating ... ...

Q = 9.25925925925928E-05

STEP 3: Convert Result to Output's Unit

9.25925925925928E-05 Cubic Meter per Second -->8.00000000000002 Cubic Meter per Day (Check conversion here)

FINAL ANSWER

8.00000000000002 ≈ 8 Cubic Meter per Day <-- Average Daily Influent Flow Rate

Design Surface Loading Rate given Surface Area of Circular Settling Tank

Go Surface Loading Rate = (Peak Discharge/Surface Area)

Peak Discharge given Surface Area of Circular Settling Tank

Go Peak Discharge = (Surface Area*Surface Loading Rate)

Surface Area of Circular Settling Tank

Go Surface Area = (Peak Discharge/Surface Loading Rate)

Peak Discharge in Circular Settling Tanks

Go Peak Discharge = Average Daily Load*Peaking Factor

Influent Flow Rate given Return Activated Sludge Flow Rate Formula

Average Daily Influent Flow Rate = (Return Activated Sludge/1.25)
Q = (RAS/1.25)

What is Influent Flow?

Influent Flow is water that "flows in". This is the raw, untreated wastewater. Effluent means to "flow out". This is the treated wastewater. This water is safe for discharge to lakes or rivers.

How to Calculate Influent Flow Rate given Return Activated Sludge Flow Rate?
