ABSTRACT:
An upflow filter of the type in which a liquid influent (e.g. water) is directed upwardly through buoyant filter media particles includes a porous supporting member, preferably in the form of a screen having openings through it that are larger than the nominal size of the media particles. A layer of particulate material is positioned on the upper surface of the porous supporting member and has a nominal particle size that is greater than the size of the openings through the supporting member. This layer of particulate material includes a plurality of interstices, or passages through which filtered liquid influent can pass, and, in the most preferred embodiment, also retains the buoyant media particles in the filter.
