A pressurised stream of airsaturated water is mixed with the flocculated water and with the release of pressure, a cloud of very fine air bubbles carries the suspended solids and lighter liquids to the tank surface. Clean water overflows from the DAF tank, via an under/over- to sewer or to the next stage of the treatment process.

DAF primarily consists of a stainless steel vessel, an air delivery system, a sludge skimmer, a recirculation pump, a stainless steel saturation tank, distribution valves, and hoses. Before the wastewater enters the DAF, it undergoes chemical treatment. The chemical program is different for every plant, but the general rules stay the same.
