Abstract: A media clarifier may have a passageway, an inlet, an outlet above the inlet, a screen, and a media bed with both compressible and incompressible media. The screen may span the passageway. The media bed may be adjacent to the screen when the media clarifier is in an operational state. Particulate matter is removed from a water stream as it passes through the media bed.

Abstract: A combination biological contactor and self-backwashing filter system for water treatment is disclosed. The system may include a treatment vessel defining an upper chamber and a lower chamber. A biological contactor may be disposed within the upper chamber, and a filter may be disposed in the lower chamber. A contactor outlet conduit and inlet manifold may be used to transfer water from the biological contactor to filter cells within the filter.
