A daf (dissolved air flotation) system creates microscopic air bubbles that are attached to incoming wastewater particles in order to float them. once floated, they are separated from the wastewater and skimmed from the top and into the float scum chamber. the treated wastewater then exits from near the bottom of the daf.
Abstract. this paper presents a physicalmathematical model for dissolvedair flotation (daf). the flotation model is an important aid for gaining insight into the effect of design parameters such as bubble diameter, particle size, bubblevolume concentration, contact time, temperature and surface load.

How daf works. dissolved air flotation (daf) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening.. daf is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed by settling.
