Dissolved air flotation Description
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.
Dissolved Air Flotation Feature
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 percent, release rate as high as 99 percent.
Tiny bubbles and suspended particles of efficient adsorption, improve the SS remove effect.
Dissolved gas water dissolving efficiency 80-100 percent, 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.
