How Dissolved Air flotation Systems for Water Treatment,

Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter.DAF Wastewater Treatment System - biocellwater,Dissolved air flotation [DAF] is a treatment process which removes suspended solids, oil and grease from wastewater. Many applications use the DAF process but it is particularly useful for industrial wastewater treatment as it can reduce COD by up to 90%.What is a DAF? How does a DAF Work? Dissolved Air,,Dissolved air flotation (DAF) is a water treatment process that clarifies wastewater by removing suspended 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.
