Abstract

Un procédé de traitement de flux de résidus de traitement décume est décrit. Le procédé comprend ce qui suit : la soumission du flux de résidus de traitement décume à une flottation pour produire un soupassement de capacité aqueux comprenant des contaminants dintérêt et des matières en suspension; lajout dun produit chimique dimmobilisation au soupassement de capacité aqueux afin dimmobiliser chimiquement les contaminants dintérêt; lajout dun floculant de polymère à un soupassement de capacité aqueux afin de floculer les matières en suspension, produisant ainsi une matière floculée; et la déshydratation des matières en suspension afin de produire une composante aqueuse appauvrie dans les contaminants dintérêt et les matières en suspension; et une composante enrichie en solides comprenant les contaminants dintérêt enrichis en solides, y compris les contaminants dintérêt chimiquement immobilisés et les solides floculés.
