 Description

Dissolved air flotation machine(DAF)is manufactured by our factory and mainly used for solid-liquid separation and liquid-liquid separation.

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.

 

Product Description

 In the water treatment process, solid-liquid separation and its equipment are one of the key projects. DAF dissolved air flotation is one of the most effective methods whose specific gravity is close to 1.0 form water. 

Feature 1

 DAF dissolved air flotation has several features as follows:

l Small footprint, lower energy consumption; easy operation and simple management

l High efficiency of dissolved air, stable treatment effects. Electro-mechanic instruments are integrally controlled

l This equipment's dissolved air efficiency reaches up to 90%. But its volume is only one fifth of the ordinary dissolved air system. Moreover, it has stronger anti-clogging capability than other DAF dissolved air flotation

l This equipment uses new type dissolved air releaser with the advantages of high releasing degree and self-cleaning functions. And the average particle size of micro bubbles is about 15~30 μm

l This equipment uses chain-plate-type skimmer with advantages of stable operation and high efficiency of scraping

Feature 2

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.
