China Paper-Making DAF Dissolved Air Flotation Units Wastewater Treatment

Dissolved Air Flotation Description

Oil Water Separator Wastewater Plant Treatment DAF Dissolved Air Flotation is an efficient flotation method for water clarification. The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form. These bubbles attach to any particles in the water causing their density to become less than that of water. The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.

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.
