Abstract

L'invention concerne la mesure de l'activité d'une boue activée chargée par un courant d'eau résiduaire. Elle se caractérise en ce que, dans un système fermé, la fourniture d'oxygène 6 est déclenchée par la détection 7 d'une concentration en oxygène inférieure à une limite, et l'oxygène fourni est introduit dans un courant d'air 9 traversant la boue activée 2. Application : installations d'épuration.
