Abstract

Biological filter in which rectilinear baffles direct the effluent along an extended, horizontal flow-path turning it through 180 degrees at the end of each straight run, is improved by a shallow cylindrical pan in which a spiral wall directs the flow of effluent over a constantly curving path with no sharp changes of direction. The flow of effluent is not slowed down at 180 degrees turns thus reducing deposition of solids.
