Dissolved Air Flotation Introduction
Dissolved Air Flotation 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 into the water or making
wastewater under pressure and then releasing the air atmospheric
pressure in a flotation tank basin.
The released air forms tiny bubbles which adhere to the suspended
matter causing the suspended matter to float on the water surface
where it may then be removed by a skimming device.
Dissolved Air Flotation Working Process
The wastewater enter RT1 (coagulation reaction tank) and RT2
(flocculation reaction tank) from the equalization tank through the
lift pump, and coagulates with PAC floculates with (PAM)
respectively form the flocs.
Then the wastewater and dissolved water enter the reaction zone of the DAF tank, and the microbubbles and flocs in the dissolved water are mixed and adhered to form solid particles ,which the density less than water, and float up to the surface of the DAF tank.
Under the action of buoyancy, scum is scraped to the slag tank. The clean water is collected down to the collect tank through the water collecting pipe, and most of the outer water is discharged (or into the next process), and a small part of the water is recirculated to form the dissolved water.

How to Select the Right Model of Dissolved Air Flotation
1. Wastewater type:
Dairy wastewater, car washing wastewater, slaughter house
wastewater, food wastewater, river water......
2. PH: 6~9 is preferred.
Consider PH adjust tank before DAF tank, also have to consider the material of the DAF due to Corrosive substance.
Consider PH adjust tank before DAF tank, also have to consider the material of the DAF due to Corrosive substance.
3. SS content (ppm or mg/L)
4. Oil & Grease &Fat & FOG content (ppm or mg/L)
5. BOD, COD (ppm or mg/L)
