Big Capacity Dissolved Air Flotation Equipment For Water Clarification




    Dissolved Air Systerm has ingenious structure, and its efficiency of dissolving air is as high as 90%. But its volume is only one-fifth of the other kind of dissolved air system.

   In addition, it still has the super anti-clogging ability which is incomparable;Release effect and the mean diameter of microbubble is only between 15 to 30 microns. In addition that,this kind of dissolved air releasers also has the self-cleaning ability.This device also applies Chained Scum Skimmer, works Smooth and reliably and skims scum efficiently.

Work Principle


   Dissolved Air Flotation is the process of removing grease, oils and other fineSuspended solids and reduces COD and BOD device. the use of air bubble flotation. Air was dissolved into water, the air -saturated water generated from dissolved air micro bubbles attach to the surface of solids,The light of solids(less dense than water)lifting them to the surface.distributed over the whole tank width,make suer optimum phase separation. Mechanical skimmer remove the floating sludge layer and thepurified wastewater discharges to sewer.


   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.


Application in Various Industry


The aim of dissolved air flotation is to separate the fine suspended solids in water, algae and micro-floc. And dissolved air flotation can be used in the following industries:


l Separate or recycle waste oil or grease in : oil exploration and refining, biodiesel, machining , food production and catering and so on.

lBiochemical effluent liquid separation: the anaerobic effluent solid-liquid separation, aerobic (activated sludge process, contact oxidation, filter) biochemical water solid-liquid separation, the secondary settling tank Effluent treatment and so on.

l Farm and slaughter house wastewater treatment: cattle, pigs, chickens farm, slaughter house wastewater.

l Manufacturing waste: electroplating, painting, etc.

lPurification: river, landscape, recycle water and so on.

lHigh concentration organic wastewater treatment: paper, printing and dyeing, textile, leather, pharmaceutical, fermentation wastewater and so on.
