Ecologix Environmental Systems Dissolved Air Flotation V Series V-725

Dissolved Air Flotation is a standard process for separating suspended solids from a waste stream. A recirculation loop of pressurized water is saturated with dissolved air using a multistage impeller pump. The product of this process is termed "whitewater." Whitewater discharges into calculated points along the pipe flocculator. Microscopic air bubbles become entrained in the floc particles. When the floc particles leave the pipe flocculator and enter the body of the DAF, they rise to the surface and form a sludge blanket. As the sludge blanket thickens, a skimmer drive transfers sludge to the DAF sludge sump. From the sump, sludge is pumped to dewatering equipment. The treated water flows from the DAF vessel and on to further processing. 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 will not float 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 assure that there are never any dead zones in the sludge skimming zone.
