Abstract

La présente invention concerne un capteur de qualité d'eau et un système de télésurveillance, qui sont équipés pour analyser et gérer une qualité d'eau dans une usine de traitement d'eau et, plus particulièrement, un système de prise de décision d'expert basé sur un capteur de qualité d'eau et un système de télésurveillance dans une usine de traitement d'eau, apte à réduire des coûts de travail en ajoutant, à un capteur de qualité d'eau classique et un système de télésurveillance classique dans une usine de traitement d'eau, un système de prise de décision par un expert, en nécessitant ainsi moins de main d'œuvre que pour une gestion directe sur site ; et permettant également une gestion en temps réel plus précise de l'usine de traitement d'eau en raison de la prise de décision de l'expert.
