Dissolved air flotation (DAF) is a reliable and proven process for purification in wastewater systems, DAF is used for the easy separation of suspended matters in liquids. The DAF System works by saturating the process water with air under high pressure which is then released to normal pressure and piped into the wastewater tank. The micro bubbles generated during pressure release work to attract suspended particles in the liquid and float them to the surface where they are then skimmed away. 

 

Dissolved air flotation (DAF) can also be used in Aquaculture or fishpond farming to increase Dissolved Oxygen.
