Development of a Nitrogen Removal Technology to Integrate with the Novel ‘EnRec’ Energy Recovery Sewage Treatment Process

The aim of this project is to develop a nitrogen removal technology to integrate with the novel energy recovery sewage treatment process, EnRec. EnRec is presently being developed as part of a collaborative R&D activity between the partners, and is partly supported by a Queensland Government (QSEIF) grant which was awarded in November 2002. One important issue yet to be addressed is how to achieve nitrogen removal in the EnRec process. One of the major differences between the EnRec process and conventional sewage treatment technology is that the main process reactor is anaerobic, thus eliminating aeration costs and enabling methane production. However, anaerobic treatment processes do not provide significant nitrogen removal, and thus it will be necessary to integrate a nitrogen removal technology with the main energy recovery process. This is the aim of this project. The project is an APA(I) PhD student project.
