What Is DAF Dissolved air flotation
Dissolved air flotation DAF Industrial 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.Air flotation separation technology of DAGYEE Dissolved air flotation DAF Industrial dissolved air into water at certain working pressure. In the process, pressurized water is saturated with dissolved air and is discharged into a flotation vessel. The microscopic air bubbles produced by released air attach to suspended solids and float them to the surface, forming a sludge blanket. A scoop removes the thickened sludge. Finally, it complete purifies the water.
As a waste water process, DAGYEE DAF dissolved air flotation is widely used in sewage treatment and water purification engineering. DAF dissolved air flotation is suitable for :
- Increase effluent recycling and fresh water reusing in paper and pulp
- Removal of heavy metal ions
- Separation of oil refinery effluent
- Removal of tannery wastewater
- Removal of chromaticity and impurities in printing and dyeing wastewater
- Solid-liquid separation of sewage and membrane after all kinds of bio-treatment
- Sludge concentration (capacity: 20%~ 30%, except the dedicated device which can be designed according to the requirements)
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.
