The socio-economic benefits to Australia will include (i) new knowledge for the multiparameter assessment of nano and ultrafine particles, pollutants in the centre of current scientific, medical and policy debates (ii) a breakthrough in the scientific understanding of traffic generated particles in the urban atmosphere (iii) determining the toxicological impact of these particles on biological systems. The ultimate economic benefit will be improved urban design to lower human exposure to ultrafine particles, thus reducing health care cost and productivity losses. The research will also place Australia at the forefront of international progress towards better methods for achieving environmental sustainability.Read moreRead less

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.

Building resilience in wastewater infrastructure with self-healing bioconcrete. This project aims to develop a microbial self-healing bio-concrete to extend the service life of wastewater collection and treatment facilities. Water utilities worldwide struggle with asset management, because global warming and extreme weather age and corrode concrete infrastructure.

This project aims to develop a microbial self-healing bio-concrete to extend the service life of wastewater collection and treatment facilities. Water utilities worldwide struggle with asset management, because global warming and extreme weather age and corrode concrete infrastructure. This project will use microbially-induced calcium carbonate precipitation by bacteria to treat wastewater. The bacteria, added to bio-concrete, can fill cracks or reseal corroded areas by using organic substrates from wastewater to generate concrete, thus maintaining structural strength and preventing further damage. This project is expected to enhance the resilience and sustainability of wastewater infrastructure in ever more demanding environments.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.

Summary
Maximising waste-to-energy technologies by overcoming microbial inhibition. This project aims to understand microbial inhibition and acclimation mechanisms that limit anaerobic digestion. 30% of waste in Australia is organic, and most is sent to landfills. Anaerobic digestion is a low-cost treatment technology that diverts organic waste to renewable energy production, but is under-used due to inhibitory compounds (e.g. ammonia, salts and heavy metals) and limited knowledge of microbiology.

This project aims to understand microbial inhibition and acclimation mechanisms that limit anaerobic digestion. 30% of waste in Australia is organic, and most is sent to landfills. Anaerobic digestion is a low-cost treatment technology that diverts organic waste to renewable energy production, but is under-used due to inhibitory compounds (e.g. ammonia, salts and heavy metals) and limited knowledge of microbiology. Understanding microbial capacity and inhibition/acclimatisation mechanisms is expected to drive greater application of anaerobic technology by enabling new processes and super-charging energy production from existing infrastructure. This would support Australia’s transition to a reliable, low-cost, low-emission and secure energy future.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.
