This project aims to develop new technology to enable stable autotrophic nitrogen removal from domestic wastewater. The technology selectively suppresses the growth of nitrite-oxidising bacteria using a by-product of wastewater treatment – free nitrous acid. Maximising energy recovery from wastewater and providing greenhouse gas neutral water services have been the targets of water utilities in Australia and worldwide. The project will potentially change wastewater management and bring economic, environmental and social benefits to water utilities.

该项目旨在开发新技术，实现生活废水中稳定的自养脱氮，该技术利用废水处理的副产品——游离亚硝酸来选择性地抑制亚硝酸盐氧化细菌的生长，并最大限度地回收废水中的能量。温室气体中性供水服务一直是澳大利亚和世界各地水务公司的目标，该项目将有可能改变废水管理，并为水务公司带来经济、环境和社会效益。
