Eutrophication is a concerning environmental problem worldwide that results in algae blooms, oxygen depletion, damages to aquatic life and public health, water quality issues, and loss of aesthetics in water reservoirs. Nutrient (e.g., nitrogen and phosphorus) discharges from wastewater, agricultural, urban, and residential runoff promote eutrophication in receiving water bodies. In terms of nitrogen removal, conventional biological nitrogen removal (BNR) is a common technique used in many wastewater treatment plants (WWTP). However, BNR requires aeration for nitrification and organic carbon input for denitrification. In WWTP, the aeration represents a considerable investment in terms of energy costs. Recent technologies involve applying …
