Abstract

La présente invention concerne un dispositif de floculation en tuyau-réservoir à haut rendement, comprenant un floculateur tubulaire (1) et un réservoir de floculation statique (2) ; le réservoir de floculation statique (2) est relié à une extrémité arrière du floculateur tubulaire (1), met en tampon et fait floculer le matériau évacué à partir du floculateur tubulaire (1). L'invention concerne également un réservoir de régulation (3), qui est relié à une extrémité arrière du réservoir de floculation statique (2) et qui régule la pression pour le matériau évacué du réservoir de floculation statique (2) afin de faire flotter le floculus. Le dispositif de floculation réalise un premier mode de floculation "dynamique puis statique" par un premier mélange intime au moyen du floculateur tubulaire (1), qui est suivi par une mise en tampon au moyen du réservoir de floculation statique (2), ce qui permet d'obtenir une efficacité de floculation élevée et une meilleure performance de floculation, de réduire la teneur en eau et d'augmenter le taux de récupération des matières solides tout en ayant une grande capacité de manipulation, et en étant approprié pour une large gamme de concentrations. La structure bien conçue du floculateur tubulaire (1), du réservoir de floculation statique (2) et du réservoir de régulation (3) assure un processus de floculation plus stable et sûr, permet une longue durée de vie, et réduit la quantité d'agents de floculation utilisée.
