Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressurein a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be remove

Dissolved Air Flotation an overview ScienceDirect Topics

Dissolved air flotation operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the ‘float’, is skimmed off as sludge (Section 7.19).The clarified water is removed from the bottom and is sometimes called the subnatant or ‘floated’ water.

Daf Floats Lightweight ParticlesDrinking Water ClarificationDesalination PretreatmentWastewater TreatmentDAF is used to separate solids from a liquid through the use of very fine air bubbles. These bubbles stick to the suspended matter — whether it’s algae, oil, or another contaminant — temporarily reducing its density. The buoyant bubbles cause the particulates to rise to the surface.
