Title (EN) BIO-ELECTROCHEMICAL SENSOR, SYSTEM AND METHOD FOR MONITORING AND CONTROLLING ORGANIC CARBON LEVELS IN A WASTEWATER TREATMENT PROCESS
(FR) CAPTEUR BIOÉLECTROCHIMIQUE, SYSTÈME ET PROCÉDÉ DE SURVEILLANCE ET DE RÉGULATION DES NIVEAUX DE CARBONE ORGANIQUE DANS UN PROCESSUS DE TRAITEMENT D'EAUX USÉES
Abstract:
(EN) The present disclosure generally relates to a system for monitoring and/or controlling the delivery of one or more organic carbon compounds to a wastewater treatment system. The system comprises a bio-electrochemical sensor to monitor metabolic activity of a population of exo-electrogenic bacteria and provide an electrical output corresponding with the metabolic activity, the bio-electrochemical sensor comprising an electrode pair and a power source to deliver a voltage across the electrode pair, and an electrical output analyzer to analyze the electrical output and correlate the electrical output with a value representing the amount of the one or more organic carbon compounds in the wastewater treatment system. A method and sensor for monitoring and/or controlling the delivery of one or more organic carbon compounds to a wastewater treatment system are also provided.
(FR) La présente invention concerne dans l'ensemble un système de surveillance ou de commande de l'apport d'un ou de plusieurs composés de carbone organique à un système de traitement d'eaux usées. Le système comprend un capteur bioélectrochimique pour surveiller l’activité métabolique d’une population de bactéries exoélectrogènes et fournir une puissance électrique de sortie correspondant à l’activité métabolique, le capteur bioélectrochimique comprenant une paire d’électrodes et une source d’alimentation pour fournir une tension de part et d’autre de la paire d’électrodes, et un analyseur de courant pour analyser la puissance électrique à la sortie et corréler la puissance électrique avec un ou plusieurs agents dans le système de traitement d’eaux usées. L'invention concerne également un procédé et un capteur pour surveiller ou commander l'administration d'un ou plusieurs composés de carbone organiques à un système de traitement d'eaux usées.
