Activated sludge treatment:

This method uses an aerated reactor where are growing populations of micro-organisms

in charge of degradation of dissolved organic pollutants (COD, BOD5).

This reactor is coupled to a clarifier for the physical separation of the treated effluent and biomass by settling.

The treatment of nitrogen compounds (nitrates) is possible by the development in the aerated basin

of anoxia working range (lack of ventilation) or by establishing a separated basin of anoxia (unventilated) upstream.
