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. 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.


Dissolved Air Flotation Feature


Corrosion-Resistant
Our plants are fabricated with marine-grade aluminum alloys and stainless steel to provide superior resistance to chemicals and corrosion, resulting in longer life.
Cost-Effective
Our packaged DAF plants are pre-assembled and pre-tested in our controlled facility, often saving 50 percent or more over in-situ construction. They can also be integrated into pre-engineered building systems for increased savings and reduced schedule. Their small footprint also reduces building costs.
Simplicity
Our DAF plants are quiet, simple and easy-to-operate with minimal operator input. They are also supplied complete with chemical dosing, water quality instrumentation, automatic controls and monitoring systems customized to meet local needs.
