Définition
Sens technique
Biomass of microorganisms used for treating wastewater from their pollutants (mainly organic matter). Microorganisms are free, suspended in the wastewater, kept inside an aeration tank, and feed on the pollutants. Then, the separation of activated sludge and water occurs in a clarifier: a part of the sludge is put back into the aeration tanks, while the other part (corresponding to the increase of stock) is discharged.
