Description

What Is DAF Dissolved air flotation

Dagyee DAF System proactively promotes solid/liquid separation providing better contaminant removal, more efficient chem usage and drier sludge – using a much smaller footprint than conventional DAFs. The DAF System is often referred to as a 'DAF on Steroids'. However, as opposed to DAF's that require significant retention time and rely on the old-school particle collision process to float solids, the DAF  System injects air into 100% of the waste stream while pushing water through a series of hydrocyclones  under controlled pressure, removing up to 100% of TSS & FOG. Chemicals are uncoiled in the Heads availing more than 2x the charge sites resulting in a higher rate of contaminant removal. Since separation occurs in the Heads, large tight flocs float and are skimmed off the tank into a sludge hopper. Drier sludge ensues as the air dissipates and chemicals recoil, to naturally dewater the flocs. Costs are reduced due to lower chemical, sludge handling and building costs.

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.
