Mixed Liquor Suspended Solids in Aeration Tank using Maximum Solids Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mixed Liquor Suspended Solids = (Maximum Solids in Aeriation Tank/((Peak Discharge+Return Activated Sludge)*8.34))
X = (Sa/((Qp+RAS)*8.34))
This formula uses 4 Variables
Variables Used
Mixed Liquor Suspended Solids - (Measured in Kilogram per Cubic Meter) - Mixed Liquor Suspended Solids (MLSS) are the concentration of suspended solids in the mixed liquor of an aeration tank, indicating the amount of biomass, typically measured in mg/L.
Maximum Solids in Aeriation Tank - (Measured in Kilogram per Second) - Maximum Solids in Aeriation Tank refer to the highest concentration of suspended solids, such as biomass and particulates, maintained for effective treatment.
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 is the portion of settled biomass that is recycled from the secondary clarifier back to the aeration tank in a wastewater treatment process.
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: 37.5 Million Liters per Day --> 0.434027777777778 Cubic Meter per Second (Check conversion ​here)
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 = (Sa/((Qp+RAS)*8.34)) --> (38/((0.434027777777778+0.000115740740740741)*8.34))
Evaluating ... ...
X = 10.4950430484724
STEP 3: Convert Result to Output's Unit
10.4950430484724 Kilogram per Cubic Meter -->10495.0430484724 Milligram per Liter (Check conversion ​here)
FINAL ANSWER
10495.0430484724 10495.04 Milligram per Liter <-- Mixed Liquor Suspended Solids
(Calculation completed in 00.007 seconds)
