Paper: Suspended Particle Extractor (SPX) For Removing Oil and Oily Wastes From Water

A flotation system is described wherein an extremely high concentration of micro bubbles is introduced into the water to assure a high probability of particular flotation. No pumps are required to supply dirty water directly to the system thus minimizing undue emulsification of suspended oil droplets. Coagulants and other chemicals readily facilitate flotation in the event that emulsions or colloidal material are present.
