<p>A method for treating effluents, in particular waters containing pathogenic or non-pathogenic microorganisms with the aid of a membrane bioreactor (R) for biologically purifying by using a compatible biomass consists in forming a loop (B) for treating the bioreactor mixed liquor in such a way that the level of concentration of microorganisms therein is reduced, wherein said treatment consists in carrying out a solid/liquid separation (12) with a cut-off threshold selected in such a way that the microorganisms, in particular targeted by the method, remain in a liquid phase (L) and a purifying biomass is retained in a solid phase (S), in carrying out a disinfecting and/or sterilising treatment (D) of the liquid phase and in returning the thus treated liquid phase to the bioreactor.</p> |
