Mixed Liquor Suspended Solids in Aeration Tank using Maximum Solids Solution

STEP 0: Pre-Calculation Summary

Formula Used

MLSS = (Maximum Solids in Aeriation Tank/((Peak Discharge+Return Activated Sludge)*8.34))
X = (S_a/((Q_p+Q_r)*8.34))
This formula uses 4 Variables

Variables Used

MLSS - (Measured in Kilogram per Cubic Meter) - MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).
Maximum Solids in Aeriation Tank - (Measured in Kilogram per Second) - Maximum Solids in Aeriation tank entering the clarifier in circular settling tank.
Peak Discharge - (Measured in Cubic Meter per Second) - Peak Discharge is the maximum volume flow rate passing a particular location during an event.
Return Activated Sludge - (Measured in Cubic Meter per Second) - Return activated sludge flow rate will vary with each installation and with different load factors.

STEP 1: Convert Input(s) to Base Unit

Maximum Solids in Aeriation Tank: 38 Kilogram per Second --> 38 Kilogram per Second No Conversion Required
Peak Discharge: 4 Cubic Meter per Second --> 4 Cubic Meter per Second No Conversion Required
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

X = (S_a/((Q_p+Q_r)*8.34)) --> (38/((4+0.000115740740740741)*8.34))

Evaluating ... ...

X = 1.13905577022714

STEP 3: Convert Result to Output's Unit

1.13905577022714 Kilogram per Cubic Meter -->1139.05577022714 Milligram per Liter (Check conversion here)

FINAL ANSWER

1139.05577022714 ≈ 1139.056 Milligram per Liter <-- MLSS

(Calculation completed in 00.004 seconds)
