A breakthrough nitrogen removal based archaeal ammonia oxidation process for wastewater treatment
Project Member(s): Liu, Y.
Start year: 2016
Summary: The discovery of ammonia-oxidizing archaea (AOA) not only dramatically improved our understanding of the global nitrogen cycle, but also provided new possibilities for novel biological nitrogen removal from wastewater. However, the potential and practical application of AOA during wastewater treatment is still very limited at present. This project aims to generate significant advancement in fundamental knowledge of AOA and provide direct support to identify optimal conditions for the process driven by AOA. Hence, it will be beneficial to the development of the novel cost-effective autotrophic nitrogen removal technology to substantially save energy consumption and reduce carbon footprint during wastewater treatment.
