sedimentation dissolved air flotation system

About Dissolved Air Flotation

Dissolved air flotation (DAF) clarifiers remove suspended solids from water.They are a cost effective alternative to conventional sedimentation clarification processes. The advantages of DAF clarifiers are their ability to treat a wide range of suspended solids in water at a high rate of solids removal and for wastewater sludge thickening.

Flotation As Primary Treatment of Waste Water (explained

(2) dissolved air flotation. In dispersed air flotation, air is introduced directly into the liquid through a revolving impeller or through diffusers. The air bubbles generated in dispersed air flotation systems are normally about 1mm in diameter and they usually cause turbulence which breaks up fragile floe particles.

Dissolved air flotation

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 tank basin.
