Perlite particles, after being expanded and treated with a silicone have the ability to selectively absorb hydrocarbons while rejecting water on or in which the hydrocarbons may be present. A carefully designed cartridge having an apertured top and an apertured bottom permits runoff water to percolate through a body of particulate perlite so that the desired separation can be accomplished. The cartridge in which the perlite is contained is easily removed from a catch basin when the perlite has become spent. The cartridge may then be opened and the spent perlite removed after which the cartridge may be refilled with fresh perlite and replaced in the catch basin.

Particules de perlite qui, après avoir été expansées et traitées au moyen de silicone, ont la propriété d'absorber sélectivement des hydrocarbures tout en rejetant l'eau dans laquelle des hydrocarbures peuvent être présents. Une cartouche soigneusement conçue comprend une partie supérieure perforée et une partie inférieure perforée pemettant à l'eau de ruissellement d'être filtrée à travers un corps de particules de perlite de façon à obtenir la séparation recherchée. La cartouche de perlite peut être facilement enlevée du bassin collecteur lorsque la perlite devient usée. La cartouche peut être ouverte pour enlever les particules usées de perlite et les remplacer par des nouvelles, puis la cartouche est remise dans le bassin collecteur.
