What is the basic principle of DAF machine

DAF machine is the air into the water, producing tiny bubbles, because of the mutual particle adsorption between bubbles and small suspended solids, the formation of a flotation body, the use of bubble rise, floating on the surface of the water, forming foam or scum, so that the suspended solids in the water can be separated.

There are three basic forms of DAF machine: aerated DAF, dissolved DAF (pressurized volume DAF, dissolved air in vacuo DAF), and electrodielectric air float.
