Volume of Wasted Sludge Per Day given MLSS Solution

STEP 0: Pre-Calculation Summary

Formula Used

Volume of Wasted Sludge per day = (MLSS*Volume of Tank)/(Concentration of solids*Sludge Age)
Q_w = (X*V)/(X^R*θ_c)
This formula uses 5 Variables

Variables Used

Volume of Wasted Sludge per day - (Measured in Cubic Meter per Second) - Volume of wasted sludge per day is measured in terms of discharge.
MLSS - (Measured in Kilogram per Cubic Meter) - MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).
Volume of Tank - (Measured in Cubic Meter) - Volume of tank is defined as the capacity of flocculation and mixing tank.
Concentration of solids - (Measured in Kilogram per Cubic Meter) - Concentration of solids in the returned sludge or in the wasted sludge.
Sludge Age - (Measured in Second) - Sludge Age is the average time for which the particle of suspended solids remains in aeration.

STEP 1: Convert Input(s) to Base Unit

MLSS: 1200 Milligram per Liter --> 1.2 Kilogram per Cubic Meter (Check conversion here)
Volume of Tank: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required
Concentration of solids: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
Sludge Age: 5 Day --> 432000 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_w = (X*V)/(X^R*θ_c) --> (1.2*9)/(0.002*432000)

Evaluating ... ...

Q_w = 0.0125

STEP 3: Convert Result to Output's Unit

0.0125 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.0125 Cubic Meter per Second <-- Volume of Wasted Sludge per day

(Calculation completed in 00.004 seconds)

What is sludge wasting ?

Wasting removes solids buildup in the activated-sludge system, formed when solids amounts in the aeration-tank influent are greater than the solids amounts in the secondary-clarifier effluent. If sludge is not wasted, the secondary clarifier eventually fills up with solids.

How to Calculate Volume of Wasted Sludge Per Day given MLSS?

Volume of Wasted Sludge Per Day given MLSS calculator uses Volume of Wasted Sludge per day = (MLSS*Volume of Tank)/(Concentration of solids*Sludge Age) to calculate the Volume of Wasted Sludge per day, Volume of Wasted Sludge Per Day given MLSS calculates volume of wasted sludge per day when we have prior information of other parameters used. Volume of Wasted Sludge per day is denoted by Q_w symbol.
