ME ME-DAF Dissolved Air Flotation DAF Microbubbles, 10000L/Hour, Membrane & Engineering Environ-Tech Co., Ltd. (CAT#: STEM-GMAE-4771-LGZ)

Dissolved Air Flotation (DAF) is a technology used extensively for wastewater treatment in food plants, oil & gas, mining,pulp & paper, dyeing & textile ,many major industries and municipal/domestic wastewater plants. It also has a very good fit for its use in clarification of drinking water treatment, especially for difficult to flocculate, low temperature, coloured waters, and waters subject to algae/biomass blooms.DAF works extremely well for waters that have fats, oils, grease, and very fine particles. DAF can be used by itself as a clarifier, but when used with chemicals such as a coagulant and a flocculent, it becomes a physical/chemical process. A properly functioning DAF will remove:
• 90-99% of Total Suspended Solids (TSS)
• 90-98% of Fats, Oils & Grease (FOG)
• 90-95% of insoluble Biochemical Oxygen Demand (BOD)
• 50-90% of colourful molecule /chemical group
A DAF unit would just be a gravity separator (essentially a sink/float tank) if it were not for the air bubble being introduced.In the DAF, micro sized air bubbles are added to the water, providing buoyancy to adhesion to the impurities particals surface. The impurities float to the surface and form a sludge layer, ready for separation. So it is very important that how to fabricating many fine/micron air bubbles, in which have an effect on removal of impurities of efficiency .

Air infusion/transfer module
The supersaturation of water is made possible by the equilibrium that exists between the dissolved concentration of a air in a liquid, and the partial pressure of that air above the liquid. The proportionality constant that relates the partial pressure to the concentration in the dissolved phase is called Henry’s Constant. The mass transfer modules contain hydrophobic microporous hollow fibers(the right diagrams) that provide a very large interface area of fiber for the mass transfer of air into the liquid. This air infusion module can infuse as much stabilized air into water with type of dissolved air and fine micro bubbles.

Air liquid pump and micro-bubbles enhance dissolved system
This is the main components in the flotation system. By eliminating the needs for large volumes of air and water used by typical pressure components, the system uses air dispersion technology and pumping force for more efficient saturation.
*eliminates excess air in the pump
*producing lots of 10 μm air bubbles
*reduced air and water consumption
*low retention time of 8-12 seconds
*retrofitting options for existing DAF treatment system
*easy changeover to meet recycling requirements for varying wastewater
