Solid Liquid Separation DAF Dissolved Air Flotation Micro Bubble Industrial Water Treatment

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.

Dissolved Air Flotation Feature

Small footprint, Low energy consumption;

Easy operation;

Simple management;

Efficient dissolved air;

Stable treatment effect ;

Full-automatic operation;
Dissolved Air Systerm is used in this device. It has ingenious structure, and its efficiency of dissolving air is as high as 90%; But its volume is only one-fifth of the other kind of dissolved air system. In addition, it still has the super anti-clogging ability which is incomparable;

Release effect and the mean diameter of microbubble is only between 15 to 30 microns. In addition that,this kind of dissolved air releasers also has the self-cleaning ability;

This device also applies Chained Scum Skimmer, works Smooth and reliably and skims scum efficiently.
