Biological Nutrient Removal (BNR) is an advanced wastewater treatment process designed to reduce the concentration of nitrogen and phosphorus compounds in effluent before discharge into natural water bodies. This method leverages microbial metabolic pathways to convert soluble nutrients into gaseous or solid forms, thereby preventing eutrophication and protecting aquatic ecosystems. BNR systems are integral to modern wastewater treatment plants, particularly in regions with stringent environmental regulations.
A Biological Oxidation is a decomposition of complex organic materials by microorganisms. Occurs in self-purification of water bodies and in Activated Sludge wastewater treatment.
