Dueler® DAF Dissolved Air Flotation
The heart behind a PEWE DAF's aeration technology is the Rogue MAX RGT ® pump. The regenerative turbine pump design creates the specific conditions necessary for dissolving air efficiently. Coupled with the Dueler ® DAF, this super saturated water releases uniform 20-30 micron bubbles into the flotation system and effectively floats fine suspended solids.
