Title
(EN) COAGULATION/FLOCCULATION APPARATUS FOR THE TREATMENT OF A HYDRAULIC FLOW, AND IMPLEMENTATION PROCESS
(FR) APPAREIL DE COAGULATION/FLOCULATION POUR LE TRAITEMENT D'UN FLUX HYDRAULIQUE, ET PROCÉDÉ DE MISE EN OEUVRE
Abstract
(EN) Coagulation/flocculation apparatus for the treatment of a hydraulic flow of any type of liquid, upstream of a physical separation element, in particular upstream of a flotation unit, or of a filtration unit, in particular a membrane filtration unit, which apparatus comprises at least one coagulator with injection of coagulant, followed by a flocculator, which are successively passed through by the hydraulic flow, in which apparatus: the coagulator comprises a reactor (1) for injection of coagulant under high energy, followed by a low-energy coagulation reactor (2); an intermediate high-energy element (3) is placed between the coagulation reactor (2) and the flocculator (4); and the flocculator is a static flocculator of piston type (4) having the same width as the physical separation element (5) located downstream.
(FR) Appareil de coagulation/floculation pour le traitement d'un flux hydraulique de tout type de liquide, en amont d'un élément de séparation physique, en particulier en amont d'un flottateur, ou d'une unité de filtration, notamment à membranes, lequel appareil comporte au moins un coagulateur avec injection de coagulant, suivi d'un floculateur, successivement traversés par le flux hydraulique, appareil dans lequel : le coagulateur comporte un réacteur (1 ) d'injection de coagulant sous forte énergie, suivi d'un réacteur de coagulation (2) à basse énergie; un élément intermédiaire (3) à forte énergie est disposé entre le réacteur de coagulation (2) et le floculateur (4); et le floculateur est un floculateur statique de type piston (4) de même largeur que l'élément de séparation physique (5) situé en aval.
