Disclosed is buoyant filtration media including a buoyant backbone support and a material disposed in or on the surface of the buoyant backbone support where the filtration characteristics of the filtration media are dependent on the material being disposed in or on the buoyant backbone support. In one embodiment, foamed polypropylene pellets are embedded with ceramic spheroids such that the buoyant media retains its buoyancy yet exhibits the characteristics of ceramic filter media.

L'invention concerne un milieu filtrant flottant comprenant un support structurel flottant et un matériau disposé dans ou sur la surface de ce support structurel flottant. Les caractéristiques de ce milieu filtrant dépendent du matériau disposé dans ou sur le support structurel flottant. Dans une forme de réalisation, des sphéroïdes de céramique sont incrustés dans des granules en polypropylène expansé, de manière que le matériau flottant conserve sa flottabilité tout en présentant les caractéristiques d'un milieu filtrant céramique.
