How does a dissolved air flotation for water clarification work?

Jan. 16, 2018

A recirculation loop of pressurized water is saturated with dissolved air using a multistage impeller pump. The product of this process is now termed “whitewater”. The whitewater is then discharged into the influent pipe and DAF vessel. Microscopic air bubbles attach themselves to the flocculated sludge particles causing them to rise to the surface to form a sludge blanket. As the sludge blanket thickens, a scrapper mechanism transfers the sludge to the DAF sludge compartment. From there, the sludge is pumped into an outside sludge holding tank and finally to dewatering equipment. Dissolved Air Flotation (DAF) systems are highly efficient at removing contaminants from wastewater. They achieve superior results at higher flow and contaminant loadings than can be achieved by other conventional gravity separation systems. Our revolutionary V-shaped design in combination with Lamella Tubes (Inclined Tubes) remove up to 99% of TSS/FOG and up to 75% of BOD loadings. Our proprietary design produces an unsurpassed dissolved air-to-solids ratio and clarifies polluted water with unmatched performance.
