The biomass establishes itself in the reactor on a fixed support enabling selection of an effective bacterial flora, i.e. capable of digesting the biodegradable polluting load optimally.
The support’s specific surface area of 100 m²/m³ minimum in accordance with EN 12255-7, as well as its geometry, enables very good adherence of the biofilm, well distributed and homogenous oxygenation and zero risk of clogging.
