The Dissloved Air Flotation DAF Separator provides effective separation of suspended solids, fats, oils and greases from liquids. Flotation of the solids is accomplished by the introduction of tinny air bubbles into the process water. As the bubbles rise, they attach themselves to the particles in suspension and carry them to the surface for ...

necessary. In this respect dissolved air flotation has proved to be superior to sedimentation in many cases. Basic work on the uses and dimensioning of flotation plants in waste water treatment by Jedele (1984), Hn (1988), Bennoit et al. () have shown that very good results can be achieved with this separation process. To reduce the ...
