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.

Directly Transforming Sewage Sludge into High-value Liquid Bioenergy. This project aims to develop an innovative technology and the underpinning science to gain renewable liquid bioenergy from sewage sludge and realise sludge reduction on an economical and safe platform, by directly transforming sewage sludge into high-value medium chain fatty acids, allowing for easy collection, storage and transportation. Wastewater treatment is generating an increasing quantity of carbon-rich sewage sludge, w ....Directly Transforming Sewage Sludge into High-value Liquid Bioenergy. This project aims to develop an innovative technology and the underpinning science to gain renewable liquid bioenergy from sewage sludge and realise sludge reduction on an economical and safe platform, by directly transforming sewage sludge into high-value medium chain fatty acids, allowing for easy collection, storage and transportation. Wastewater treatment is generating an increasing quantity of carbon-rich sewage sludge, which typically represents a substantial, but largely untapped, renewable resource. The intended outcome of the project will transform sewage sludge from a troublesome waste stream to a valuable resource that can be applied in existing sludge treatment infrastructure for addressing Australia’s increasing energy demand.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
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
