Abstract

Process and apparatus for extracting the ordinary and colloidal suspension materials from the waste water, more particularly, but not exclusively, in a single operation, the process being characterized in that in a first zone of the reactor close to the feed, the waste water is treated by coagulant and flocculating reagents and by water saturated in air under pressure injected through the flow of wastewater, in order to collect on the surface of this area the ordinary materials in suspension, and because in a second zone of the apparatus, close to the exit of the clean waters, flocculated colloidal materials, suspended in the first zone and dragged to this second zone, are separated by rapid separation cells.
