What Is DAF Dissolved air flotation
WWTP DAF unit Industrial Wastewater,Oil Water Separator Wastewater Plant
Treatment DAF Dissolved air flotation is an efficient flotation method for
water clarification. The term refers to the method of producing flotation by
dissolving air in the water under pressure and then releasing the pressure.
When the pressure is released the solution becomes supersaturated with air as
millions of small bubbles form. These bubbles attach to any particles in the
water causing their density to become less than that of water. The particles
then rapidly float to the surface for collection and removal, leaving the
clarified water behind.
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
