What Is DAF Dissolved air flotation
Dosing Tank DAF System WWTP plays an important role in solid-liquid separation
Simultaneously reduce COD, BOD, chroma. Firstly, mix flocculating into raw
water and stir thoroughly. After the effective retention time, the raw water
enters into the reaction zone where microscopic air bubbles adhere to the floc
and then flows into the separation zone. Under the buoyancy effects, the tiny
bubbles float the flocs to the surface, forming a sludge blanket. skimmer
removes the sludge into the sludge hopper. Then the lower clarified water flows
into the clean-water reservoir through the collecting pipe. Some of water are
recycled to the flotation tank for the air dissolving system, while others will
be discharged.
DAF Dissolved air flotation Process
Dissolved air pump edge bibulous the edge is inspiratory, pump pressurized mix within, gas to liquid efficient dissolving, small bubbles than 30 um
Low voltage operation, the dissolved gas efficiency is as high as 99 percent, release rate as high as 99%
Dissolved gas water dissolving efficiency 80-100%, than traditional dissolved gas floating high efficiency 3 times
Pressure-capacity curve smooth, easy to achieve automatic control, easy to operate, easy maintenance, low noise
