A method of removing a liquid contaminant from a liquid having a greater density than the contaminant. A first step involves positioning a layer of buoyant non- absorbent powder at an interface between the liquid contaminant and the liquid, such that the layer of buoyant non-absorbent powder lifts the liquid contaminant out of the liquid. A second step involves removing the liquid contaminant from the surface of the layer of buoyant non-absorbent powder. In accordance with the teachings of this method rubber powder from recycled tires has been successfully used to remove hydrocarbons from water.
Méthode permettant de retirer un contaminant liquide d'un liquide dont la masse volumique est supérieure à celle du contaminant. La première étape consiste à placer une couche de poudre flottante non absorbante à l'interface entre le contaminant liquide et le liquide, de telle sorte que la couche de poudre soulève le contaminant hors du liquide. La seconde étape consiste à retirer le contaminant liquide se trouvant à la surface de la couche de poudre flottante non absorbante. Selon cette méthode, on a utilisé avec succès de la poudre de caoutchouc provenant de pneus recyclés pour retirer des hydrocarbures de l'eau.
