Dissolved Air Flotation (DAF System) is a high-efficiency water treatment process designed to clarify wastewater by removing suspended solids, oil, and grease. It is widely utilized for solid-liquid separation, effectively reducing COD and BOD levels, making it a cornerstone equipment for modern wastewater management.
The GFA system produces dissolved air water, which is released under reduced pressure to create 15-30um micro bubbles. These bubbles attach to suspended solids, reducing their density and causing them to float to the surface. A scum layer is then formed and removed by the skimmer into a sludge tank, while clean water is collected from the bottom. Approximately 30% of the clean water is recycled back into the GFA system.
