Oil Water Separator--Dissolved Air Flotation Unit (DAF Machine)

Dissolved Air Flotation machine, short for DAF, it is main machine used to remove the TSS and oil.
It is widely used in the pre-treatment process for the wastewater treatment.
The TSS and oil removal rate can reach above 90%, at the same time it can remove some COD around 30~50%.

Product Description

气浮组合1. Description

YW series 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.

 

2. Application

(1) Remove oil and TSS, oil water separator.

(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.

 

3. Features

(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.
