Candy Carbon® Denitrification in an Activated Sludge System

For many municipal wastewater treatment facilities, removing inorganic nitrogen to permitted discharge levels is a challenging requirement. Without the role of biological nutrient removal (BNR) in treatment systems, effluent wastewater will have high concentrations of nitrogenous species. Specifically, discharging nitrate loads into surface waters can have adverse impacts on aquatic environments, including eutrophication and toxic algal growth. Because of this, wastewater facilities are obligated to keep their biological treatment functioning properly.
