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
Oil content in outlet water can be reduced less than 1mg/L
Broken ring, broken chain, decolorization, deodorant, disinfection
No man need on duty
The skid mounted structure is available out-of-the-box
No polymer consumption, low cost of investment and operating
An efficient performance of solid and liquid seperation,whicn is from unique dissolved air and micro bubble manufacturing technology.
