SFF eliminates the need for clarifier solids inventory management while providing high-rate treatment.

The key difference from IFAS is the lack of a return activated sludge line (RAS), eliminating the suspended growth biomass.

Fixed media means easy, quick and inexpensive installation. When you are ready to expand, addition of modules is also both effective and affordable.

SFF Features
  • attached growth biomass only
  • tends to have pin floc
  • enables pre-treatment without clarifier
  • works well in combination with DAF
