Dissolved air flotation machine (DAF) is widely used for solid-liquid 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 separation of the liquid-solid and liquid-liquid.

By the compressor,the air will be sent into air tank.Then it will be taken in air dissolved tank by jet flow device.In the dissolved tank,the air will be liquefied under 0.35Mpa pressure.Then the liquefied are will be sent to air flotation tank.When released suddenly, the air will be dissolved out and turn into a microbubble group.The group will meet the flocculating suspension in the sewage which is sent by pump and already medicated.It will be absorded in the flocculated suspension while slowly rising up.Along with reduction of the suspension's density,the suspension will go up to the water surface.Finally,the SS and CODcr will be removed. 

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