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.
