Abstract

Procédé et dispositif pour le contrôle du traitement de l'eau dans une installation de clarification au moyen d'un agent coagulant, du type dans lequel la turbidité d'un échantillon de l'eau traitée est mesurée en continu après séparation des matières coagulées, caractérisés en ce que l'on prélève sur l'eau brute, c'est-à-dire avant son passage sur l'installation, deux échantillons, à savoir un premier échantillon qui reçoit une dose d'agent coagulant inferieure à la dose utilisée dans l'installation et un second échantillon recevant soit une dose encore inférieure à la précédente, soit une dose supérieure à la dose précédente, et, après séparation des matieres coagulées, on observe la différence de turbidité entre le premier et le second échantillon pour en déduire la nature de l'anomalie éventuelle du traitement subi par l'eau dans l'installation
