Aeration Industries' new Aire-O
2 Bio-
ffilm® fixed film media system offers a cost effective wastewater treatment facility upgrade that increases plant performance and capacity by providing year-round nitrification and BNR. The Bio-
ffilm system is a submerged attached-growth process using proprietary fabric technology with a high effective surface area. Our research and development engineers have integrated the media into a treatment system using Aire-O
2 Triton® aerators to establish and maintain biological growth on the media. The aerators are sized and oriented relative to the media arrangement to provide the proper amounts of mixing and aeration for solids suspension, nutrient treatment, and oxygen diffusion. The aerators also maximize treatment kinetics by maintaining higher basin temperatures in cold weather. The system is ideal for municipal wastewater treatment facilities needing upgrades of advanced treatment to meet more stringent EPA requirements or capacity increases.
