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 pressure in a flotation flotation.

Dissolved air floatation daf is a widely used clarification process especially in india. daf removes particles from water using air bubbles that collide and attach to particles. the particle bubble aggregates are then separated once they rise to the surface of the tank. the most common method of producing air bubbles is the pressurized flotation.Dissolved air flotation systems daf are a wastewater treatment process that floats and flocculates particles in wastewater to removes suspended matter like oil or solids. it works by dissolving air in the water under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.How flotation technology works. solids are floated in the clarifier by chemical coagulation and flocculation, and by adding microbubbles. the microbubbles are created in an unpacked saturator which combines 8 to 15 recycle from the clarified water with compressed air. the pressurized air/water mixture is sent through a row of nozzles or flotation.

About dissolved air flotation

2 dissolved air flotation. in dispersed-air flotation, air is introduced directly into the liquid through a revolving impeller or through diffusers. the air bub bles generated in dispersed air flotation systems are normally about 1mm in diameter and they usually cause turbulence which breaks up fragile floe parti cles.9 rows dissolved air flotation is the preferred option for primary treatment where the flotation.
