Dissolved Air Flotation is widely used for separating solids, fats, oil, and grease from a waste stream. In the process, pressurized water is saturated with dissolved air and is discharged into a flotation vessel. The microscopic air bubbles attach to solids and float them to the surface, forming a sludge blanket. A scraping assembly skims the sludge off the surface of the water and into a sump. From the sump, sludge is pumped to dewatering equipment. The treated water flows from the DAF vessel for discharge or on to other treatment processes.
The V-Series DAF system is engineered to address the inefficiencies common to other system designs. We incorporated a V-shaped flotation cell with a sludge auger so any solids that resist flotation can be automatically removed from the base of the vessel. The skimmer assembly is made of materials that don't scale, foul, or corrode. The adjustable weir and scraper assembly assures that there are never any dead zones or carry overs in the sludge skimming zone. As a result, the V-Series can achieve up to 99% removal of TSS, FOG and 75% of BOD. Dissolved Air Flotation system pair well with flocculation tubes, chemical reaction tanks, and chemical feed systems.
