Product Description
DAF dissolved air flotation machine for Suspened Solid Remove
DAF is an alternative clarification process that uses micro air bubbles to attach and float flocculated particles and suspended solids to the water surface for removal.In contrast, sedimentation removes settled solids from the bottom.
Before the flocculated water enters the clarification chamber, millions of tiny air bubbles are released from the diffuser nozzles to the water, which attach and float the floc particles to the water surface. The air bubbles are generated in a pumped recycle stream by an air compressor and are dissolved in water through a packed-tower-type of saturator. The floated sludge is removed periodically to a desludging trough, and the clarified water flows to the bottom of the clarifying chamber and then to an effluent control weir for collection. The air saturator is used to dissolve air in the water and then generate bubbles to float the floc particles.
By the compressor,the air will be sent into air tank.Then it will be taken in air dissolved tank by jet flow device.In the dissolved tank,the air will be liquefied under 0.35Mpa pressure.Then the liquefied are will be sent to air flotation tank.When released suddenly, the air will be dissolved out and turn into a microbubble group.The group will meet the flocculating suspension in the sewage which is sent by pump and already medicated.It will be absorded in the flocculated suspension while slowly rising up.Along with reduction of the suspension's density,the suspension will go up to the water surface.Finally,the SS and CODcr will be removed.
- Some of the main advantages of DAF include better performance for removing light particles such as algae, which are difficult to settle. DAF can also usually achieve lower effluent turbidity than settling, typically less than 0.5 NTU. It is not as sensitive to temperature, especially cold temperatures as is common in settling, and the startup time is very short, approximately 30 minutes. Further, DAF does not need to generate heavy floc for settling, so lower coagulant dosage and shorter flocculation time can be used. The process can also operate at much higher surface loading rates (SLR) than sedimentation, especially in the high-rate DAF processes, which can be up to 20 gpm/ft2.
