Separation of oil from water by dissolved air flotation ...

2002-9-4  Dissolved air flotation (DAF) is a process for removing suspended particles from liquid by bringing the particles to the surface of the liquid. Air is dissolved at high pressure in a saturator, and microbubbles are formed when water is released in the flotation cell at atmospheric pressure.

Oil/Water Separation by Induced-Air Flotation

Removal of dispersed oil from water is usually accomplished by either dissolved- or dispersed-gas flotation. The processes are similar: gas bubbles are introduced into the oil-containing liquid and the oil drops are captured by the gas bubbles which quickly rise to the surface where the oil is removed.
