Determination of the fate of dissolved organic nitrogen in biological nutrient removal (BNR) processes and development of appropriate treatment technologies (2004–2007)

Abstract:
The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology. As a result of tightening effluent N licence requirements for sewage treatment plants, the dissolved organic nitrogen (DON) fraction has become extremely important. In many cases, the DON forms the major fraction of the effluent N, and is constraining further reductions in licence specifications, and in some cases it is the cause of failure to meet licence. DON is refractory (un-biodegradable), very poorly characterised, its fate in conventional biological treatment processes not known, and its eventual impact on the environment unknown. Considering its importance, it is critical that these issues are addressed. This proposal intends to address some of them. This project is an APA(I) PhD student project.
