Summary
Removing a Key Barrier for Autotrophic Nitrogen Removal from Wastewater. 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 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.Read moreRead less
Sustainable wastewater management. This project aims to extract high-value liquid products (medium-chain fatty acids) from wastewater with minimised greenhouse gas emissions and energy consumption, in addition to clean water. Traditional wastewater treatment removes organic carbon and nutrients by using vast amounts of energy and releasing greenhouse gas. However, wastewater is a substantial but largely untapped renewable resource. The intended outcome is to transform wastewater from a troubleso ....Sustainable wastewater management. This project aims to extract high-value liquid products (medium-chain fatty acids) from wastewater with minimised greenhouse gas emissions and energy consumption, in addition to clean water. Traditional wastewater treatment removes organic carbon and nutrients by using vast amounts of energy and releasing greenhouse gas. However, wastewater is a substantial but largely untapped renewable resource. The intended outcome is to transform wastewater from a troublesome pollutant to a valuable resource and reduce carbon footprints.Read moreRead less
Novel concepts for bioelectrochemical generation of renewable fuels and chemicals from wastewater. Global warming and the diminishing fossil fuel resources are posing an ever increasing threat to our societies and economies. This project aims to develop novel and highly innovative bioelectrochemical processes for the production of valuable fuels and chemicals from wastewater, which is a largely untapped renewable resource.
Unravelling the dynamics of nitrous oxide production in wastewater systems. This project aims to unravel the dynamics of Nitrous oxide (N2O) production in wastewater treatment systems by combining continuous stable isotope tracing techniques with innovative experimental design and sophisticated mathematical modelling. Nitrous oxide (N2O) is a potent greenhouse gas and a major contributor to the carbon footprint of wastewater treatment systems. Yet we have a poor understanding of how it is produc ....Unravelling the dynamics of nitrous oxide production in wastewater systems.

Nitrous oxide (N2O) is a potent greenhouse gas and a major contributor to the carbon footprint of wastewater treatment systems. Yet we have a poor understanding of how it is produced in such systems. The outcomes of this project will benefit Australian water utilities by helping them to reduce N2O emissions.Read moreRead less

Summary
Reducing nitrous oxide emission in wastewater systems by pathway regulation. Nitrous oxide (N2O) is a potent greenhouse gas that can be produced during biological nitrogen removal in wastewater treatment systems. N2O emissions primarily occur in aerated zones due to active striping, and ammonia-oxidizing bacteria (AOB) are the major contributors to N2O production under such conditions. The project aims to carry out a systematic study on N2O production by AOB in mixed culture wastewater treatment ....Reducing nitrous oxide emission in wastewater systems by pathway regulation.

The project aims to carry out a systematic study on N2O production by AOB in mixed culture wastewater treatment systems. The project aims to advance the fundamental knowledge on N2O production pathways by AOB under different operational conditions, and deliver a modelling tool for reliably estimating N2O emission from wastewater treatment systems as well as strategies to reduce the emissions.Read moreRead less

Summary
Novel biotreatment for micropollutant removal from contaminated water. Micropollutants in contaminated water create major environmental challenges to water resource management in Australia. This project will use a novel biological process to remove micropollutants from water resources sustainably and ensure clean drinking water for Australians.
Micro-managed biofilm - next generation environmental biotechnologies. Eutrophication in waterways due to the presence of nitrogen creates major environmental challenges in inland Australia. This project will develop novel biological nitrogen removal technology, through management of microbial composition to achieve sustainable high-level nitrogen removal from wastewaters and benefical reuse of the water.
Bio-electrochemical sulfate reduction and sulfur recovery without external carbon source. Highly acidic waterways and mining wastewaters create major environmental challenges in inland Australia. This project will use novel, solar driven biological processes to remove the acid and metals from these streams and enable beneficial reuse of the water and other resources recovered in the process.
