Abstract

L'invention concerne un procédé et une installation d'épuration biologique d'eau résiduaires suivant la méthode à boue activée, avec séparation de la boue activée de l'eau résiduaire épurée et recyclage au moins partiel de la boue activée séparée. On maintient la concentration des impuretés dégradables dans l'eau résiduaire entrante à un niveau à ce point élevé qu'elle favorise la formation de boue aérée et l'on élimine par centrifugation D la boue aérée de l'eau résiduaire épurée. Applications : retraitement des eaux résiduaires.
