Dissolved Air Flotation Process in Wastewater

Dissolved air flotation DAF is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water then releases it at atmospheric pressure.

Dissolved air flotation

2018 10 26&ensp·&enspDissolved 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.
