submerged aerated fixed film (SAFF)

It is based on the principle of treatment by immersed and aerated fixed biomass. Oxygen will activate bacteria that will degrade the pollution present in the water.

our technology

The oxyfix® uses SAFF technology, which provides stability, effectiveness and durability for wastewater treatment.


treatment for your large-scale projects

The SAFF process is particularly well suited for treating the wastewater of small and medium communities thanks to its ease of use and optimal yields.
