WAS Pumping Rate from Aeration Tank Solution

STEP 0: Pre-Calculation Summary
Formula Used
WAS Pumping Rate from Reactor = Reactor Volume/Mean Cell Residence Time
Qw = V/θc
This formula uses 3 Variables
Variables Used
WAS Pumping Rate from Reactor - (Measured in Cubic Meter per Second) - WAS Pumping Rate from Reactor is the total amount of waste activated sludge that comes out from the reactor.
Reactor Volume - (Measured in Cubic Meter) - The Reactor Volume gives us the capacity of the reactor.
Mean Cell Residence Time - (Measured in Second) - Mean Cell Residence Time is the average time that the sludge remains in the reactor.
STEP 1: Convert Input(s) to Base Unit
Reactor Volume: 1000 Cubic Meter --> 1000 Cubic Meter No Conversion Required
Mean Cell Residence Time: 7 Day --> 604800 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qw = V/θc --> 1000/604800
Evaluating ... ...
Qw = 0.00165343915343915
STEP 3: Convert Result to Output's Unit
0.00165343915343915 Cubic Meter per Second -->142.857142857143 Cubic Meter per Day (Check conversion here)
FINAL ANSWER
142.857142857143 142.8571 Cubic Meter per Day <-- WAS Pumping Rate from Reactor
(Calculation completed in 00.004 seconds)

4 WAS Pumping Rate Calculators

WAS Pumping Rate from Return Line given Wasting Rate from Return Line
Go WAS Pumping Rate from Return Line = (Reactor Volume*MLSS/(Mean Cell Residence Time*Sludge Concentration in Return Line))-(Effluent Flow Rate*Solid Concentration in Effluent/Sludge Concentration in Return Line)
WAS Pumping Rate from Return Line given RAS Pumping Rate from Aeration Tank
Go WAS Pumping Rate from Return Line = ((MLSS/Sludge Concentration in Return Line)*(Average daily influent flow rate+Return Activated Sludge))-Return Activated Sludge
WAS Pumping Rate using Wasting Rate from Return Line when Concentration of Solid in Effluent is Low
Go WAS Pumping Rate from Return Line = Reactor Volume*MLSS/(Mean Cell Residence Time*Sludge Concentration in Return Line)
WAS Pumping Rate from Aeration Tank
Go WAS Pumping Rate from Reactor = Reactor Volume/Mean Cell Residence Time

WAS Pumping Rate from Aeration Tank Formula

WAS Pumping Rate from Reactor = Reactor Volume/Mean Cell Residence Time
Qw = V/θc

What is aeration tank?

Aeration tank where air (or oxygen) is injected in the mixed liquor. Settling tank (usually referred to as "final clarifier" or "secondary settling tank") to allow the biological flocs (the sludge blanket) to settle, thus separating the biological sludge from the clear treated water.

How to Calculate WAS Pumping Rate from Aeration Tank?

WAS Pumping Rate from Aeration Tank calculator uses WAS Pumping Rate from Reactor = Reactor Volume/Mean Cell Residence Time to calculate the WAS Pumping Rate from Reactor, The WAS pumping rate from aeration tank is the total amount of waste-activated sludge that comes out from the reactor. WAS Pumping Rate from Reactor is denoted by Qw symbol.
