AccuFAS® Submerged Fixed-Film Applications

There is a growing burden for wastewater treatment plants including demands to treat greater flows due to population growth or industrial production, as well as increasingly stringent discharge permits. 

Added complexities such as budgets, space constraints, and existing facility structures, as well as regional variations in temperature and rainfall, require treatment systems that can adapt to each unique application. Brentwood’s AccuFAS Submerged Fixed-Film system offers a solution for plants requiring greater treatment capacity in existing basins, better nitrification with consistent seasonal performance, and biological nutrient removal to meet strict effluent total nitrogen limits.

The AccuFAS system, which can be used in any treatment configuration in existing or new treatment facilities, incorporates structured-sheet media as a fixed-film surface to foster biomass growth without increasing clarifier solids loadings. As overall biomass inventory multiplies, plants can treat more flow to a greater degree without costly basin construction. In addition to increasing treatment capacity, conventional activated sludge facilities can improve and stabilize nitrification by retrofitting existing basins with AccuFAS in an Integrated Fixed-Film/Activated Sludge (IFAS) configuration. The same biofilm benefits translate to BNR applications where the increased surface area enhances aerobic basin performance, making AccuFAS an economical solution for plants requiring lower total nitrogen levels.

Tank Enviro Systems will evaluate your current processes, permit requirements, and site-specific needs of your treatment plant. With extensive experience in the wastewater industry, Tank Enviro Systems can custom design submerged fixed-film solutions for every application.
