High-efficiency Air Flotation Equipment

WHICH IS MORE EFFICIENT–SUSPENDED AIR FLOTATION(SAF)OR DISSOLVED AIR FLOTATION(DAF)? Skid Mounted SAF Unit Which is more efficient–Suspended Air Flotation(SAF)or Dissolved Air Flotation(DAF)? Suspended Air Flotation(SAF)is the next generation of solids removal for industrial and municipal waste streams.This process is capable of greater solids removal than a conventional dissolved air flotation(DAF)system while using a footprint up to ten times smaller.How does SAF achieve these better efficiencies?The process uses an externally-generated bubble suspension with high air content.Each bubble is covered with a chemically active film which strongly attaches to the flocculated solids in the water being treated,achieving high rate and efficient flotation.DAF,by contrast,uses high pressure to dissolve a small amount of air in water with no chemically active agent, and depends on physical entrapment and a weak surface bond to float the flocculated solids.
