Abstract

PURPOSE: Filter materials lighter than water are floated on sewage providing an extremely simple, cheap contact aerator which eliminates the need for a third treatment device.
CONSTITUTION: Lighter-than-water materials 3 such as pumice, foam concrete, processed polyethylene, foamed resin material, mesh assembly, nonwoven assembly are floated on sewage in aeration tank 1. So constructed device enables to simplify sewage treatment.
