<p>Described is a system for the aerobic purification of waste (5), in particular wastewater, in which the waste is treated in an aeration chamber (11) in which a substantially constant oxygen concentration is maintained. This system is provided with a calculating unit (30) receiving a signal indicative of the amount of oxygen instantaneously consumed per unit of time, and producing an output signal indicative of the instantaneous pollution burden. <IMAGE></p> |
