Abstract

PURPOSE: To remove BOD efficiently by permitting a gas-liquid contact of water which is falling in a layer of a granular material with coexisting air, by a process in which quantity of feed water in a reaction tank is adjusted and coexisting air and water being treated in the layer of the granular material descend along the grains.
