MLSS in Oxygen Requirement of the Aeration Tanks Formulas

MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics). And is denoted by X. MLSS is usually measured using the Milligram per Liter for Density. Note that the value of MLSS is always positive. Typically, the value of MLSS lies in the range from 1000 to 6500.

FAQ

What is the MLSS?

MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics). MLSS is usually measured using the Milligram per Liter for Density. Note that the value of MLSS is always positive. Typically, the value of MLSS lies in the range from 1000 to 6500.

Can the MLSS be negative?

No, the MLSS, measured in Density cannot be negative.

What unit is used to measure MLSS?

MLSS is usually measured using the Milligram per Liter[mg/L] for Density. Kilogram per Cubic Meter[mg/L], Kilogram per Cubic Centimeter[mg/L], Gram per Cubic Meter[mg/L] are the few other units in which MLSS can be measured.
