1.Product Description:
Dissolved air flotation system for wastewater treatment is mainly for solid-liquid or liquid-liquid separation. Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or liquid particles with same density as waste water to make the whole float to the surface thus achieve the aim of solid-liquid or liquid-liquid separation.
2.Application: 
As a waste water process, DAF is widely used in sewage treatment and water purification enginnering. This equipment is suitable for :
a.Increase effluent recycling and fresh water reusing in paper and pulp.
b.Removal of heavy metal ions.
c.Separation of oil refinery effluent.
d.Removal of tannery wasteeater.
e.Removal of chromaticity and impurities in printing and dyeing wastewater.
f.Solid-liquud separation of sewage and membrane after all kinds of bio-treatment.
g.Sludge concentration ( capacity: 20%-30%, except the dedicated device which can be designed according to the requirements).
3. Features: 
1.Large capacity, high efficiency and small occupying space.
2.Compact structure, easy operation and maintenance.
3.Silt expansion elimination
4.Aerate to the water while air floating, it has an obvious effect to the elimination of active agent and foul smell in water. Meanwhile, the increased dissolved oxygen provides a favorable condition to the follow-up process.
5.It can achieve the best effect in adopting this method when disposing the water with lower temperature, lower turbidity and more algae.
