Commercial tests of cationic flocculant in flotation treatment of waste water
This work has been aimed at testing the efficiency of a polyacrylamide with cationic properties in the flotation separation of oil matter from waste water under industrial conditions. The N-dimethylaminated polyacrylamide that they synthesized manifests the properties of a high-molecular-weight cationic polyelectrolyte. This particular flocculant was selected because of its relatively high flocculating power, the sharp reduction that it gives in the volume of slime (foam) in reagent flotation treatment of waste water, and the lower content of mineral salts in the treated water. Commercial tests of the cationic flocculant were performed at the Gor'kii petroleum oil plant. The treating facilities in this plant include the following: reagent section, pumping station, flotation unit, and section for gravitational compaction of oil slime rejected from the flotation cell.
