Summary
Efficient PFAS removal from urban wastewater using a novel two-step approach. This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining ....Efficient PFAS removal from urban wastewater using a novel two-step approach. This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining smoldering process which will render the captured PFAS to small ash, condensate and gaseous streams suitable for established destruction technologies. The project is expected to provide support to water utilities in achieving sustainable water treatment and result in environmental and social benefits to the community.Read moreRead less
On-line monitoring of cyanobacteria to predict coagulant doses and powdered activated carbon application in water treatment. Cyanobacteria, more commonly known as blue-green algae, can impact water quality by releasing toxins that can be harmful to human health and imparting unpleasant taste and odours to the water. This project will support the water industry in managing these risks by providing a rapid, on-line tool to assist in their removal during water treatment.
Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will ....Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will consider silica and silica-rich nanoparticles in concert with cations and organics, with the aim of better managing cations so to facilitate nanoparticle lubrication. Project outcomes may include more productive use of assets, improved pre-treatment infrastructure to support reverse osmosis operation, and the environmental benefits of reduced chemical waste and increased water recovery.Read moreRead less
Ozone-Enhanced Particle Removal in Water Treatment. Combined ozonation/biologically active carbon filtration provides effective contaminant removal while minimizing disinfection by-product formation. However, the cost of installation in conventional water treatment plants is very high. This project will investigate the beneficial influence of ozonation on the micro-flocculation of small particles, with the aim to optimising particle removal by sedimentation prior to filtration. To do this, requi ....Ozone-Enhanced Particle Removal in Water Treatment. Combined ozonation/biologically active carbon filtration provides effective contaminant removal while minimizing disinfection by-product formation. However, the cost of installation in conventional water treatment plants is very high. This project will investigate the beneficial influence of ozonation on the micro-flocculation of small particles, with the aim to optimising particle removal by sedimentation prior to filtration. To do this, requires a clear understanding of how dissolved ozone interacts with particle surfaces for different water chemistries. The ideal outcome would be to develop a robust water treatment system that required BAC filtration only and eliminated the need for a conventional sand filtration stage as well.Read moreRead less
Assessment and optimisation of N-nitrosamine rejection by reverse osmosis for planned potable water recycling applications. Water recycling is a strategic approach to secure potable water supplies in Australia.

Water recycling is a strategic approach to secure potable water supplies in Australia. The underlying challenge is to protect public health by ensuring robust treatment processes capable of effectively eliminating contaminants of concern. This research aims to enhance the capabilities of advanced water treatment plant designers and operators to control N-nitrosamine concentrations by optimised reverse osmosis treatment. A predictive model will be developed allowing for the optimisation of N-nitrosamine removal by reverse osmosis filtration in full scale installation. The project will directly enhance the viability of indirect potable water recycling and thus reduce dependency on water sources vulnerable to climate change.Read moreRead less
Effective clinical handover communication: improving patient safety, experience and outcomes. Improving written and spoken communication in clinical handover will significantly reduce critical incidents in hospitals. The link between communication and critical incidents in hospitals is well documented.

Improving written and spoken communication in clinical handover will significantly reduce critical incidents in hospitals. The link between communication and critical incidents in hospitals is well documented. One third of the $2 billion p.a. direct financial costs to Australia of critical incidents, is attributed to poor communication between clinicians. National and international governments and health agencies have targeted clinical handover as critical in safe, effective health care. This project will generate new knowledge of handover to significantly improve patient safety and enable health professionals to enhance their communicative practices, thereby improving the quality of the patient journey through the hospital system.Read moreRead less

This project promotes public engagement and quantifies preferences in key areas of relevance to the industry partners Queensland Health and South Australia Health. These areas identified are elective surgery priorities, optimising appropriate use of emergency care, and interventions for obesity. A series of choice experiments and citizens' juries will be used. The project will facilitate identification and application of optimal methods for engaging the public in healthcare decision-making, provide guidance on the appropriate population groups to consider when eliciting consumer preferences, and provide direct public input to guide health policy. The approach will be able to be applied to different policy areas.Read moreRead less
Effective clinical handover communication: improving patient safety, experiences and outcomes. Communication in clinical handover (transfer of responsibility for patient care) plays a causal role in many adverse events. This project will contribute new knowledge for improvements in handover communication which will be shared across hospitals and health departments nationally to improve patient safety and reduce healthcare costs.
Development of nanostructured sensors for ultra-sensitive, label-free and selective detection of biological and chemical species. Outcomes will significantly advance the technical and fundamental understanding of sensor assembly and provide guidelines for developing and manufacturing nanostructured sensors, which is critical for next generation nanoscale sensing platforms for health care, medical diagnostics and chemical detection and Australia's emerging sensor industries.
