There is an acute deficiency of knowledge in Australia on urban airborne ultrafine particles, originating from transport and other anthropogenic sources, which pose significant health and environmental risks. The aim of this project is to address this deficiency by an extensive multi-city, cross-disciplinary study using state of the art instrumentation and data analytic techniques. The outcome will be an in depth, quantitative insight into the characteristics of the particles, their sources and spatial and temporal variation across different urban areas and time scales. Further, the impacts of changing fuels, vehicle technologies, and climate on future trends of the particles will be elucidated.Read moreRead less
Toxic metal removal from wastewater sludge. This project aims to efficiently remove toxic metals from wastewater sludge. Sludge management is a problem for water utilities, incurring substantial costs. Land application of wastewater sludge is a sustainable way of sludge management, but toxic metals hinder its long-term repeated application.

PFAS transport through landfill clay liners enhanced with proteins. Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans. Due to their non-stick, water and stain repellences, PFAS have long been used in everyday products (food wrappers, carpets, furniture etc.) which end up in landfills. As it is currently unknown how PFAS move through the various components of landfill barriers, their fate and transpor ....PFAS transport through landfill clay liners enhanced with proteins. Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans. Due to their non-stick, water and stain repellences, PFAS have long been used in everyday products (food wrappers, carpets, furniture etc.) which end up in landfills. As it is currently unknown how PFAS move through the various components of landfill barriers, their fate and transport has become a priority for the regulators of Australia’s landfill sites according to the Australian 2018 PFAS National Environmental Management Plan. This research will determine PFAS transport through common clay barriers enhanced with proteins which have been shown to be an excellent sorbent for PFAS.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

This project will provide significant benefits by addressing significant community objections to nearshore fish farms, including severe environmental pollution, disease and pathogens, over use of antibiotics and economic impacts on tourism.Read moreRead less
Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its ....Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its beneficial use to enhance nitrogen removal, which is otherwise typically unsatisfactory due to the lack of organic carbon to support denitrification. The project will provide strong support to the Australian water industry in their endeavour to achieve energy- and carbon-neutral wastewater services.Read moreRead less
