Enhancement of nitrogen and phosphorus removal by coupling pyrite-based autotrophic denitrification with an electro-enhanced A2/O process.
Conventional anaerobic-anoxic-oxic (A2/O) processes often exhibit low nutrient removal efficiency and high operational costs when treating carbon-limited wastewater from highway service areas. In this study, a pyrite-based autotrophic denitrification process coupled with an electro-enhanced A2/O system (PE-A2/O) was de...
