ABSTRACT:
Disclosed herein is a waste water treatment apparatus and process especially adapted for tertiary treatment of sewage wherein a plurality of biological media panels are positioned in a treatment tank in a manner such that the formation of a stable mat or film composed of solids is established thereon. Biological growth on the panels is enhanced while at the same time excessive solids build-up is avoided. Flow through the tank is directed in a generally horizontal fashion and sludge removal is accomplished by pump means.
