1.Principle

The flotation separation technology  is  make the gas maximum  dissolved in water under certain pressure conditions,   strive  to at a saturation point, and  formed pressure and dissolved in water, by the decompression release, producing a large number of tiny bubbles ,and make it full contact with water, then suspended flocculent in the water adhesion in the micro-bubbles, together with the bubbles float to the surface to form a scum, and scrape the scum, thereby purifying the water quality. our factory development of QF type shallow poolthe flotation device is an advanced fast flotation system, on the basis of conventional flotation theory, the successful use of a shallow pool theory "and" zero speed "principle, collecting cohesion, flotation,  drossing, precipitation, scrape as a group , as a water purification process of highly efficient equipment .

 2 .Application range          

Dissolved air flotation technology in recent years is widely used in the drainage and wastewater treatment, which can effectively remove the wastewater is difficult to produce frivolous flocs. Large capacity, high efficiency, small footprint, and the use of a wide range. Been widely adapted to the petroleum, chemical, printing and dyeing, paper making, oil refining, leather, iron and steel, machinery processing, starch, food such as sewage treatment.

Used in the following areas in the field of water treatment flotation

 1,Fine suspended matter, algae and other micro-polymer separation of surface water.

Dissolved air flotation (DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams., was commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals 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

 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
