Veolia Water Solutions commissions first BIOSTYR biological aerated filter in Kingston, Canada

13 May 2009

VEOLIA Water Solutions and John Meunier have started up their first BIOSTYR biological aerated filter in Canada at the Ravensview Wastewater Treatment Plant in Kingston, Ontario.

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.
