Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in res ....Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in response to ventilation and dynamic wastewater and atmospheric conditions, enabling model-based sewer ventilation design and operation. The project also aims to deliver novel, field-demonstrated ventilation strategies. The project findings will be incorporated in the Australian ventilation design and operation guidelines.Read moreRead less
Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative ....Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative that could be incorporated into DTA programs if their ecological relevance can be demonstrated. This project will develop and validate a new and internationally significant suite of in vitro bioassays for incorporation into DTA programs, leading to more ethical, cost effective and improved environmental protection.Read moreRead less

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
Mineral transformation and oxidant production in subsurface environments. Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present.

Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present. In this project, fundamental knowledge gaps regarding the impacts of redox oscillations upon contaminant behaviour in these sediments will be addressed through a comprehensive program of field studies at a purpose-constructed experimental facility in an existing waste site, and complementary laboratory investigations. The intended outcomes are to improve understanding of contaminant mobility at the field-scale in these pervasive sites spread across the globe, and provide critical insight into their remediation using cost-effective techniques.Read moreRead less
Innovative tools needed for market-based nutrient offsetting . This project will apply innovative approaches to develop a functional equivalency of nutrients from catchment versus point sources. This is fundamental knowledge needed for the successful application of nutrient offsetting. This market-based mechanism involves point source polluters choosing to pay for catchment restoration, which is offset against their nutrient discharge. Currently, despite its potential, there is a lack of confide ....Innovative tools needed for market-based nutrient offsetting . This project will apply innovative approaches to develop a functional equivalency of nutrients from catchment versus point sources. This is fundamental knowledge needed for the successful application of nutrient offsetting. This market-based mechanism involves point source polluters choosing to pay for catchment restoration, which is offset against their nutrient discharge. Currently, despite its potential, there is a lack of confidence in the scientific robustness of nutrient offsetting. The proposed new indicators in nutrient equivalency would provide the foundation needed to ensure that governments and industry can have the confidence to engage in nutrient trading schemes, ultimately ensuring environmental and social benefits.Read moreRead less

This project aims to tackle a critical challenge of groundwater management – to understand and predict the impacts of declining groundwater levels. Over pumping and declining groundwater tables are a global problem, yet the effects on the ecosystems that exist within aquifers are poorly known. This project will create a world first evidence-based model of how lowering water tables affects the microbes, invertebrates (stygofauna) and ecological processes in groundwater ecosystems, and will demonstrate the consequences of such changes to groundwater quality and availability. This model will allow impacts to be reliably forecast and avoided or mitigated, vastly improving how major developments affecting groundwater are planned and implemented.Read moreRead less
