Abstract
This invention pertains to a submerged fixed-film biological distribution system. It includes a plurality of vertical chambers adjacent each other having corrugated packings therein. Air or oxygenating gas is introduced at the bottom of select alternating chambers so that an upflowing liquor is generated in those chambers and a downflowing liquor generated in the adjacent chambers. Contaminated waste is biologically digested by microorganism retained on the corrugated packings, such digesting occurring in all chambers.
