Dissolved air flotation Wikipedia

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 The released air forms tiny bubbles which adhere to the suspended matter

Flotation Article about flotation by The Free Dictionary

Dissolved Air Flotation system DAF FPBC SIGMADAF Clarifiers

Dissolved Air Flotation DAF technology is utilised to remove oils grease solids and suspended flocculants that do not possess sufficient buoyancy to float or where an emulsion of oils and solids with increased density require air flotation to enhance the separation process

dissolved air flotation Equipment in California

Dissolved Air Flotation DAF is a mechanical process using ultra fine air bubbles to separate somewhat neutral or positively buoyant contaminants from water These contaminants form nuclei on which microscopic air bubbles coalesce The air bubbles add buoyancy to the contaminants causing them to float to the surface
