Abstract
Procédé et dispositif permettant de mélanger également des résidus fins mûrs à un floculant avant de le déposer dans une cellule de dépôt. Le procédé comprend les étapes suivantes : a) recevoir un débit fluide de résidus fins mûrs floculés et un floculant résiduel provenant dune alimentation directe; b) réduire la vitesse découlement du débit fluide et laccumuler dans une chambre, jusquà une hauteur prédéterminée; et c) permettre au débit fluide de sécouler dans un ensemble de descente, pour quil descende dune hauteur prédéterminée au moins jusquà une hauteur moindre, lensemble de descente étant configuré pour que le floculant résiduel provenant du débit fluide soit également mélangé à des résidus fins mûrs provenant du débit fluide lorsquil descend lensemble de descente, dune région plus haute vers une région plus basse. De plus, lensemble de descente est configuré pour empêcher tout surcisaillement des résidus fins mûrs floculés. Linvention concerne également une trousse constituée de composants correspondants permettant lassemblage du dispositif de dépôt.
