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.
Benefits of SAF™ = Increased Efficiency:
- Smaller footprint
- Less energy use
- Removes more solids
- More flexible operationally
- More cost effective
This technology can be a stopgap for many clients who need a cost effective, easy to operate solution to their solids handling problems. Whether you are a municipal client seeking to treat in-plant waste or recycle streams or improve your DAF’s performance; or an industrial client requiring pretreatment before sewer discharge, this technology offers many advantages for each unique scenario.
