DAF Oil Water Separator Dissolved Air Flotation For Sewage treatment

Product Description

Dissolved air flotation machine device is mainly used for solid liquid or liquid liquid separation

of a kind of water treatment environmental protection equipment products. The flotation device

is by dissolved gas and release system in water produce large quantities of fine bubbles, the

adhesion in wastewater and the density of water close to the solid or liquid particles, resulting

in the overall density lower than water, and rely on the buoyancy to enable it to rise to the

surface, so as to achieve solid - liquid or liquid - liquid separation to.

High efficient air flotation equipment introduction of new technology in Japan, using the high

efficiency pump will mix with water, gas dissolved under pressure to form a water soluble gas,

release vacuum, micro bubble precipitation and suspended particles, adsorption float, so as to

achieve solid-liquid separation.

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.

Key DAF features

1. Air dissolving pump and suction water pump suction, pressure in mixing, dissolving high

efficiency, fine bubbles is less than or equal to 30um.

2. Low pressure operation, dissolved air efficiency of up to 99%, the release rate of up to 99%.

3. The effective adsorption of micro bubbles and suspended particles increased the removal efficiency of SS.

4. Dissolved gas water solution efficiency of 80-100%, 3 times higher than the traditional

dissolved air flotation efficiency.

5. Pressure - volume curve is smooth, easy to realize automatic control, easy to operate, easy

to maintain, low noise.

Principle of DAF

The DAF Separator provides effective separation of suspended solid, fats , oils and greases from liquids by dissolved air flotation . Flotation of the solids is accomplished by the introduction of tinny air bubbles into the process water.AS the bubbles rise ,they attach themselves to the particales in suspension
