DAF System For Suspended Solids Removal Waste Water Treatment
Dissolved air flotation is one of the most effective methods whose
specific gravity is close to
1.0 from water.Dissolved Air Flotation is liquid/solid or
liquid/liquid separation process to
remove tiny suspended solids that density close to the water,
colloid , oil and grease
etc.Dissolved air flotation is an innovation combined with
traditional dissolved air flotation
concept and modern technology.
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.
