The invention concerns a method characterised in that it consists of the following steps: continuously evaluating the treated medium oxidation-reduction, for actuating the aerating means or not; during the aerating phases, measuring the oxygen concentration and using its value, jointly with those of the oxidation-reduction for: maintaining aeration if the oxygen concentration corresponds to a set value range; decreasing aeration if the oxygen concentration is less than the set range and, producing a self-adaptation of the oxygen set point values by comparing, during the "partial nitrification/total nitrification" transition of the oxidation-reduction potential, the real oxygen concentration, with the system set value range and by adjusting the set value based on said system real oxygen requirement. |
