DAF Dissolved air flotation consists of flotation tank, dissolved air system, reflux pipe, dissolved air released system, skimmer (Based on customer needs, there are combined type, traveling type and chain-plate type to choose.), electric cabinet and so on.
Air flotation separation technology of DAGYEE DAF Dissolved air flotation dissolved air into water at certain working pressure. In the process, pressurized water is saturated with dissolved air and is discharged into a flotation vessel. The microscopic air bubbles produced by released air attach to suspended solids and float them to the surface, forming a sludge blanket. A scoop removes the thickened sludge. Finally, it complete purifies the water.
DAF dilssolved air flotation is mainly used in the following aspects paper-making effluent processing and fiber recovery,wasterwater treatment in printing& dyeing; the treatment of wastewater with heavy metal ions, like electroplating wastewater; oily wastewater treatment; wastewater treatment in tanning, chemical and painting industry; solid and liquid separation of wastewater from food industry.
