A novel autotrophic biological nitrogen removal process driven by ammonia-oxidizing archaea and anammox bacteria (2013-2016)
Abstract
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.
