Veolia Water Solutions says biological aerated filters are compact treatment processes, which combine filtration and aerobic/anoxic treatment using a fixed-film biological degradation process.
According to Veolia Water Solutions, the BIOSTYR biological aerated filters use a floating polystyrene media comprised of individual spherical beads as the support for bio film growth.
Wastewater is fed in an up-flow manner through the BIOSTYR, leading to a biological abatement of the pollution, as well as physical filtration of suspended solids.
Veolia Water Solutions says the application required a compact and efficient biological treatment technology because of space restrictions.
