Dissolved Air Flotation an overview ScienceDirect

Dissolved air is the most common type of flotation gas used in potable water treatment The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water In general dissolved air flotation has proved to be as sturdy and reliable as sedimentation techniques, such as lamellae settling KEYWORDS Bacteria; dissolved air flotation; drinking water; nozzles; viruses INTRODUCTION Seven drinking water companies in the Netherlands are highly experienced with dissolved air flotationDissolved air flotation in potable water treatment: The Dissolvedair flotation as a primary clarification stage for the production of potable water is particularly effective for the treatment of algaeladen waters and lowturbidity, highly colored watersThe Advantages of Dissolved‐air Flotation for Water

Our Dissolved Air Flotation “DAF” units use a pressurized stream of water to deliver dissolved air to an incoming wastewater treatment stream that contains flocculated waste When the pressure of the dissolved air and water stream is reduced, the air effervesces out of the water and attaches itself to the waste particles Often abbreviated as a DAF system, our dissolved air floatation system is a highly efficient and economical way to remove contaminants such as total suspended solids (TSS), oils and grease (FOG), fats, and biochemical oxygen demand (BOD) from waste water streamsDissolved Air Flotation (DAF) Water Treatment For 147 Dissolved Air Flotation (DAF) for Wastewater Treatment 522 d iSperSed a ir f l oTa Tion Dispersed ai r otation has two different systems to generate bubbl es, namely, f (PDF) 5 Dissolved Air Flotation (DAF) for Wastewater
