What is a DAF? How does a DAF Work? Dissolved Air

What is a DAF ? Dissolved air flotation (DAF) is a water treatment process that clarifies wastewater by removing suspended solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank. This design works so well that often a customer will

These are electrolytic flotation, dispersed air flotation, and dissolved air flotation. The basis of electrolytic or electroflotation is the generation of bubbles of hydrogen and oxygen in a dilute aqueous solution by passing a dc current between two electrodes. The application of electrolytic flotation

Dissolved Air Flotation Theory
