Effluents are purified by a continuous activated-sludge bio-process in a unit contg. aerating and settling space(s) constructed around one (or more) vertical axis (axes). Activated sludge-streaming back from the settling into the aerating area as a consequence of fluid density differences in these areas is passed to the bottom of fluid stream(s) moving first in a vertical and then in a horizontal plane as directed by air streams appearing in the aerating area. Circulation of sludge is controlled by the volume of supplied air
