A novel autotrophic biological nitrogen removal process driven by ammonia-oxidizing archaea and anammox bacteria (2013–2016)
Nitrogen removal from wastewater is crucial to protect Australia's sensitive environments. This project will investigate the kinetic and physiological properties of the recently discovered ammonia-oxidizing archaea (AOA), and develop an innovative autotrophic nitrogen removal process by enriching AOA and Anammox, achieving completely autotrophic nitrogen removal under oxygen-limited condition. Compared to the nitrogen removal processes commonly used today, this novel autotrophic process consumes much less energy and does not require a carbon source. It can also mitigate greenhouse gas emission from wastewater.
