Flotation – Water and Wastewater Treatment

Treating wastewater from food industries is challenging due to the high levels of BOD₅, COD and fat. Specialized equipment like Dissolved Air Flotation (DAF) is needed to reduce the levels of pollutants before biological treatment. This consists of a Membrane Bio-Reactor (MBR) system Continue Reading →

Flotation: DAF, IAF, SAF - Veolia Water

1. Injection of the air while the liquid is under pressure, followed by the release of the pressure. This is called dissolved air flotation (DAF) because the air actually dissolves into the water at the increased pressure. 2. Aeration at atmospheric pressure, which is just called air flotation. Air

DAF - Worldwide Experts in Water Treatment

Dissolved Air Flotation (DAF) clarification process is typically used for the separation of fine suspended solids, grease, and oils. DAF works by producing a stream of micro-fine air bubbles that attach to solids to float them to the water's surface where they can be removed by a surface scraping mechanism.
