Oil Removal Dissolved Air Flotation DAF Dissolved Air Flotation Industrial Water Treatment

Dissolved Air Flotation Description

Air flotation technology DAF dissolved air flotation plays an important role in solid-liquid separation Simultaneously reduce COD, BOD, chroma. Firstly, mix flocculating into raw water and stir thoroughly. After the effective retention time, the raw water enters into the reaction zone where microscopic air bubbles adhere to the floc and then flows into the separation zone. Under the buoyancy effects, the tiny bubbles float the flocs to the surface, forming a sludge blanket. skimmer removes the sludge into the sludge hopper. Then the lower clarified water flows into the clean-water reservoir through the collecting pipe. Some of water are recycled to the flotation tank for the air dissolving system, while others will be discharged.

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.
