Abstract (en)

[origin: WO03053867A1] The invention concerns a method for biological treatment of effluents containing ammonium characterized in that it comprises a step which consists in passing said effluent through a reactor (1) containing a biomass at least partly fixed on a support (3) having a high specific surface not less than 500 m2/m3, said biomass being capable of degrading the ammonium contained in the effluent to a molecular gaseous nitrogen phase, said step being carried out under continuous moderate aeration, without stirring and without or with very little external input of biodegradable carbon and with a minimum of alkali reagents.
