ABSTRACT:
A water and wastewater treatment apparatus including a tank divided into a horizontal series of filtering subchambers by parallel, perforated septa. Effluent flows through the septa and through a reverse-graded media series including at least one fine medium such as sand. The media may be backwashed by counterflow and right angle flow, the latter being effective to expand and scrub one or more of the layers of media.
