Dissolved Air Flotation Units DAF Machine For Domestic Wastewater Treatment

DAF dissolved air flotation consists of flotation tank, dissolved gas system, return pipe,

dissolved gas release system, separator (according to customer demand, combined, walking

and chain plate selection), electric cabinet and so on. .

DAF air flotation separation technology dissolves air into water at a certain working pressure.

During this process, the pressurized water is saturated with dissolved air and discharged into

a flotation vessel. The tiny bubbles generated by the released air adhere to the suspended

solids and float to the surface to form a sludge layer. The spoon removes the thickened

sludge. Finally, it completes the purification of the water.

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:

1. Separate or recycle waste oil or grease in : oil exploration and refining, biodiesel, machining

, food production and catering and so on.

2. High concentration organic wastewater treatment: paper, printing and dyeing, textile,

leather, pharmaceutical, fermentation wastewater and so on.

3. Biochemical 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.

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

house wastewater.

5. Manufacturing waste: electroplating, painting, etc.

6. Purification: river, landscape, recycle water and so on.

Advantage

1. Flow rate of one set: 1-300 m³/h.

2. Recycle flow dissolved air flotation.

3. High efficiency pressurization system providing high quantity dissolved-air water to create

large quantities of small bubbles.

4. Custom design on different dissolved air flotation equipment and recycle flow ratio

according to the type of wastewater and treatment requirement to achieve target removal

effect and stability.

5. Adjustable stainless steel chain type skimmer to suit the different quantity of sludge.

6. Integrated coagulation tank and or flocculation tank and cleaning water tank(as optional)is

available to save the space and cost.

7. Automatic and remote controllable.

8. Material of construction: carbon steel epoxy painted, carbon steel FRP line, stainless steel

SS304/SS316L.
