Sludge Age given Total Solids Removed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sludge Age given Total Solids Removed = (Volume of Tank*Concentration of Solids in Effluent)/Mass of Solids Leaving the System
θ_ct = (V*X^E)/M^'
This formula uses 4 Variables

Variables Used

Sludge Age given Total Solids Removed - (Measured in Second) - Sludge Age given Total Solids Removed is the average length of time that solids (or sludge) remain in the treatment system before being removed, considering total solids removed.
Volume of Tank - (Measured in Cubic Meter) - Volume of Tank is defined as the capacity of flocculation and mixing tank.
Concentration of Solids in Effluent - (Measured in Kilogram per Cubic Meter) - Concentration of Solids in Effluent is the amount of solid particles, both suspended and dissolved, present in a liquid effluent (wastewater or other discharged liquid).
Mass of Solids Leaving the System - (Measured in Kilogram per Second) - Mass of Solids Leaving the System is the total mass of solid particles that are discharged or removed from a treatment or processing system over a given period.

STEP 1: Convert Input(s) to Base Unit

Volume of Tank: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required
Concentration of Solids in Effluent: 10 Milligram per Liter --> 0.01 Kilogram per Cubic Meter (Check conversion here)
Mass of Solids Leaving the System: 0.004 Kilogram per Day --> 4.62962962962963E-08 Kilogram per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ_ct = (V*X^E)/M^' --> (9*0.01)/4.62962962962963E-08

Evaluating ... ...

θ_ct = 1944000

STEP 3: Convert Result to Output's Unit

1944000 Second -->22.5 Day (Check conversion here)

FINAL ANSWER

22.5 Day <-- Sludge Age given Total Solids Removed

(Calculation completed in 00.004 seconds)

What is Sludge Age?

The common range for sludge age for a conventional activated sludge plant is between 3 and 15 days. For extended aeration activated sludge plants the range is between about 15 and 30 days. Generally during the winter months, higher sludge ages are required to maintain a sufficient biological mass.
