DAF System Air Flotation Machine Applied To Leather Wastewater Treatment




(1) Large capacity, high efficiency and small occupying space.


(2) Compact structure, easy operation and maintenance.


(3) Silt expansion elimination.


(5) Aerate to the water while air floating, it has an obvious effect to the elimination of active


agent and foul smell in water. Meanwhile, the increased dissolved oxygen provides a


favorable condition to the follow-up process.


(6) It can achieve the best effect in adopting this method when disposing the water with lower


temperature, lower turbidity and more algae.


Suitable area:


slaughtering, starch, pharmaceuticals, papermaking, printing and dyeing,


leather and tannery, petrochemical industry, domestic wastewater, etc.



Dissolved Air Floatation is mainly for solid-liquid or liquid-liquid separation.

Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or


liquid particles with same density as waste water to make the whole float to the surface thus


achieve the aim of solid-liquid or liquid-liquid separation.



(1) Remove oil and TSS.

(2) Separate small particles and algae in groundwater.

(3) Recover valuable products in industrial sewage such as paper pulp.

(4) Act as secondary sedimentation tank to separate and concentrate suspended particles


and sludge.





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
