Mixed Liquor Suspended Solids given Sludge Age Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

MLSS - (Measured in Kilogram per Cubic Meter) - MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).
Volume of Wasted Sludge per day - (Measured in Cubic Meter per Second) - Volume of wasted sludge per day is measured in terms of discharge.
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.
Volume of Tank - (Measured in Cubic Meter) - Volume of tank is defined as the capacity of flocculation and mixing tank.

STEP 1: Convert Input(s) to Base Unit

Volume of Wasted Sludge per day: 9.5 Cubic Meter per Second --> 9.5 Cubic Meter per Second 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)
Volume of Tank: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

X = (Q_w*X^R*θ_c)/V --> (9.5*0.002*432000)/9

Evaluating ... ...

X = 912

STEP 3: Convert Result to Output's Unit

912 Kilogram per Cubic Meter -->912000 Milligram per Liter (Check conversion here)

FINAL ANSWER

912000 Milligram per Liter <-- MLSS

(Calculation completed in 00.004 seconds)
