Description
What Is DAF Dissolved air flotation
DAF Dissolved air flotation consists of flotation tank, dissolved air system, reflux pipe, dissolved air released system, skimmer (Based on customer needs, there are combined type, traveling type and chain-plate type to choose.), electric cabinet and so on.
Why Choose DAF Dissolved air flotation
- Total suspended solids (TSS) reduced by up to 97.
- Chemical oxygen demand (COD) removal rate of up to 60-80%.
- Integrated sludge hopper for easy removal of solid deposits .
- The DAF area provides a static space for the formation of the float.
- Heavy-duty, fully protected, counter-current surface separator that removes surface float.

Dissolved air flotation
Dissolved Air flotation technology 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.
