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

Reduction in wastewater surcharges and further treatment expense.
Better energy efficiency—physical separation vs biological treatment.
Recovery of useful and marketable by-products.
Reduction in chemical usage—smaller more abundant bubbles float a finer floc.
Cost efficient, in-house manufacturing.
