This project aims to develop a real-time and high-resolution genomic tool to monitor and track pathogens in urban wastewater systems based on the portable third-generation sequencing platform. Pathogens sicken hundreds of millions of people, cost the global economy tens of billions of dollars annually, and are one of the leading causes of death worldwide. The current epidemiology approach, and data, are retrospective and thus insufficient for timely intervention. Integrated with wastewater analysis for pharmaceuticals targeting pathogens, the sewer-based epidemiology approach of this project will greatly enhance public health by achieving early detection and informed control of infectious diseases.Read moreRead less

Supply of potable water to Australia's major urban areas is a major challenge to growth and quality of life. Indirect potable reuse via membranes can address this issue, as it offers an inexpensive and sustainable water supply, as well as leveraging new water sources. However, the potential impact of the generated reject concentrates on aquatic and human health is potentially of large concern. Our project helps address this, by making reject treatment economically and environmentally much more sustainable, and thereby future-proofing the technology. In addition, it develops technology that can be used worldwide to treat other recalcitrant streams (e.g., hospital, tannery, pulp and paper), is highly scalable, and is low in operating cost.Read moreRead less

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

Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of bacteria. The project aims to investigate a particular bacterial community, which is able to perform nitrogen removal from wastewater with methane as a renewable carbon source. The project will therefore lead to more sustainable wastewater treatment systems.Read moreRead less
