TITLE OF THE INVENTION Process and installation for a biological treatment, e.g. by nitrification and/or denitrification, of an effluent including nitrated pollution. ABSTRACT TEXT A process for the biological treatment of an effluent to be treated, including nitrated pollution includes the following steps : - an incident flow of this water is brought into a mixing zone with at least one compartment in which, by turbulent mechanical agitation, a little consumed and slightly soluble granular material, loaded with biomass, is put in homogeneous suspension in this water, and is maintained at a more or less constant mass concentration; - this water and this granular material in suspension are circulated in a separation zone from which is extracted on the one hand clarified water, and on the other hand biomass loaded granular material; and - almost all of the: active biomass fixed on said granular material is brought back by forced recycling to the mixing zone.
