Abstract

L'invention porte sur un procédé de surveillance de l'activité biologique dans des fluides consistant à isoler un échantillon du fluide, à en mesurer le pH à intervalles données, à analyser les variations éventuelles du pH pour en déterminer le taux pour l'échantillon. On mesure également la quantité d'oxygène dissous dans l'échantillon à intervalles donnés, de manière sensiblement synchrone par rapport aux mesures du pH, et les variations éventuelles de l'oxygène dissous sont analysées pour déterminer le taux biologique de consommation d'oxygène de l'échantillon.
