The Aire-O2 Bio-ffilm fixed film media system aims to offer a cost-effective solution for wastewater treatment facilities that need upgrades to increase plant capacity and performance by providing year-round nitrification. The submerged proprietary geo-textile media process provides surface area for biomass growth and is paired with Aire-O2 Triton process aerators to create treatment “arrays” of mixing and aeration for solids suspension, nutrient transfer and oxygen diffusion. Installation is easy with the float-mounted Bio-ffilm system, eliminating the need for new construction and plant downtime.
The concentrated biomass creates conditions for a high degree of nitrification year-round, even during cold weather, the company said. Process is self-regulating and requires no maintenance. Dense biomass communities on the fixed film increase solids retention time in the system and provide the added benefit of facilitating simultaneous nitrification/denitrification processes.
Media can also be added to enhance BOD removal. Adding Bio-ffilm media decreases F/M ratio, which allows for possibility of applying higher influent loadings to the process.
