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
