Abstract
Disclosed is a method for managing the operation of an apparatus for injecting oxygen into a purification basin. The oxygen notably being used by the biomass present in the purification basin to consume the pollution present in an effluent feedstock contained in the basin. The method comprises varying a rotational speed of the shaft by using a frequency variator, wherein an applied variation in speed is between plus 15% and minus 15% of the nominal speed of the shaft.

A method for managing the operation of an apparatus for injecting oxygen into a purification basin, the oxygen notably being used by a biomass present in the purification basin to consume the pollution present in an effluent feedstock contained in the purification basin, the apparatus including the following components and functionalities:
- the apparatus is positioned at the surface of the purification basin and equipped with a system enabling it to be kept floating above the liquid;
- the apparatus includes a drive device, positioned above the liquid, and provided with a vertical or inclined output shaft, the shaft being equipped at its end with at least one moving part for mixing and for dispersing the injected oxygen;
- and
- the apparatus includes a system for injecting oxygen;
- the method comprising
- varying a rotational speed of the shaft by using a frequency variator, wherein an applied variation in speed is between plus 15% and minus 15% of the nominal speed of the shaft.
