Highly Efficient System For Industrial Wastewater Treatment Dissolved Air Flotation Unit

Dissolved Air Flotation Description


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. 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.
