Product Description

Dissolved air flotation machine

1. Introduction
Dissolved air flotation machine (DAF) is manufactured by our factory and mainly used for solid-liquid separation and liquid-liquid separation. Flotation device will produce large amounts of tiny bubbles by dissolved gas and release system in the water, to make the adhesion in the waste water and water close to the density of solid or liquid particles, causing the whole condition of density smaller than water, and depend on the ascend to the surface flotage, so as to achieve the purpose of the liquid-solid separation, liquid-liquid separation.

2. Work Principle:


The air will be send by air compressor into air tank, then take in air dissolved tank by jet flow device, the air will be force to dissolve into water under 0.35Mpa pressure and forming dissolved air water, then send to air flotation tank. Under the circumstance of sudden release, the air dissolved in water will be dissolve out and form vast microbubble group, which will be fully contact the flocculating suspended matter in sewage, the suspended matter was sent by pump and flocculation after adding medicine, the ascending microbubble group will adsorb in the flocculated suspended matter, made its density reduce and floated to water surface, thus reach the purpose of removing SS and CODcr etc.

3. Feature:
1).Dissolved air pump edge bibulous the edge is inspiratory, pump pressurized mix within, gas to liquid efficient dissolving, small bubbles than 30 um.
2).Low voltage operation, the dissolved gas efficiency is as high as 99%, release rate as high as 99%.
3).Tiny bubbles and suspended particles of efficient adsorption, improve the SS remove effect.
4).Dissolved gas water dissolving efficiency 80-100%, than traditional dissolved gas floating high efficiency three times.
5).Pressure-capacity curve smooth, easy to achieve automatic control, easy to operate, easy maintenance, low noise.

4. Main Structure



There is a wide range of industrial and municipal applications for DAF including:
Product recovery and reuse Pretreatment to meet sewer discharge limits 
Pretreatment to reduce loading on downstream biological treatment systems Polishing of biological treatment effluent ,thickening of biosolids
