BUOYANT FILTER MEDIA

摘要

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.
