Title
(EN) ON-LINE CONTINUOUS MONITOR TO OPTIMIZE COAGULANT AND FLOCCULENT FEED IN WASTEWATER AND PAINT SPRAY BOOTH SYSTEMS
(FR) SYSTEME CONTINU DE SURVEILLANCE EN LIGNE POUR OPTIMISER L'ADJONCTION DE COAGULANT ET DE FLOCULANT DANS DES EAUX RESIDUELLES ET DANS LES SYSTEMES DE CABINES DE PEINTURE PAR PULVERISATION
Abstract
(EN)
An apparatus and method for optimizing coagulant and flocculent chemical feed in a wastefluid treatment system is disclosed which uses two or more contaminant-concentration dependent parametric detectors to measure the detected parameter in chemically-treated wastefluid and chemically-treated, solid-separated wastefluid.
(FR)
L'invention concerne un appareil et un procédé pour optimiser l'adjonction de coagulant et de floculant chimiques dans un système de traitement de fluides résiduels, ce procédé faisant appel à deux détecteurs paramétriques ou davantage, réagissant à la concentration en contaminant, pour quantifier le paramètre mesuré dans le fluide résiduel traité chimiquement, et dans le fluide résiduel traité chimiquement et dont les matières solides ont été séparées.
