A device and method for safe, efficient and easy decontamination of waste streams, particularly dental waste streams. The contaminated stream (30), which may contain toxic metals such as mercury, contacts the inventive unit (31, 70) that both physically and chemically filters contaminants in a single stage. The unit (31, 70) contains a contaminant binding resin (34) and a mechanical filter (14), which removes both soluble and insoluble forms of the contaminant. The device and method reduce contaminants to levels which meet regulatory agency requirements for toxic metals. The device and method also allow safe handling and transport of the contaminated unit (31, 70).

Cette invention a trait à un dispositif et au procédé permettant de décontaminer en toute sécurité, efficacement et facilement des flux de déchets, notamment des flux de déchets d'origine dentaire. Le flux contaminé (30), pouvant notamment renfermer des métaux toxiques tels que du mercure, entre en contact avec l'unité selon cette invention (31, 70) qui filtre les contaminants à la fois physiquement et chimiquement en une seule opération. Cette unité (31, 70) contient une résine fixant le contaminant (34) et un filtre mécanique (14) permettant d'extraire les formes solubles et insolubles du contaminant. Ce dispositif et le procédé correspondant permettent de ramener les contaminants à un taux satisfaisant aux exigences de l'agence de régulation en matière de métaux toxiques. Ils permettent également de procéder à une manipulation et à un transport sûrs de l'unité contaminée (31, 70).
