Oily Wastewater DAF System Micro Bubble Separator Dissolved Air Flotation Petrochemical Industry

Dissolved Air Flotation Description

Air flotation technology DAF dissolved air flotation 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.
