PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. ....PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. Extensive 1D and 2D laboratory experimental programmes will be carried out. Models of unit processes that occur in infiltration systems will be defined/developed and built into a physically based model of an infiltration system. This model could be used for reliable design of stormwater drainage and harvesting systems, bringing major benefits to the people of drier and more populated areas of Australia.Read moreRead less

Reuse of the treated wastewater from sewage treatment plants (STPs) has become significantly important in Australia due to dwindling water resources. The poor quality of the wastewater has limited its use for agriculture and aquaculture. This project aims to develop a solar nano-photocatalytic tertiary wastewater treatment process for disinfection and mineralization of the treated wastewater from STPs, making the wastewater suitable as a water resource. The newly developed nano-fibre catalysts and photocatalytic technology in the teatm will be used and further developed in this novel process. The research will focus on the water quality objectives in terms of technical reliability, and economic and environmental sustainability.Read moreRead less
Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such ....Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such lakes and assess the possibility of using mining lakes as valued water resources in these regions. The primary outcome of the research will be improved management of the lakes for optimal long term water quality.Read moreRead less

Removal of Potential Impact of Pharmaceutical Active Compounds during Wastewater Treatment. The increasing application of antimicrobial compounds in pharmaceutical and personal care products (PPCPs) requires improved understanding of their impact on the environment. Wastewater treatment plants (WWTPs) are a major removal process, however little is known about why certain PPCPs are removed during wastewater treatment and other are not. The project aims to study the fate of PPCPs and the spread of ....Removal of Potential Impact of Pharmaceutical Active Compounds during Wastewater Treatment. The increasing application of antimicrobial compounds in pharmaceutical and personal care products (PPCPs) requires improved understanding of their impact on the environment. Wastewater treatment plants (WWTPs) are a major removal process, however little is known about why certain PPCPs are removed during wastewater treatment and other are not. The project aims to study the fate of PPCPs and the spread of bacterial resistance in wastewater treatment. Studies will compare the effects of different treatment processes, operational conditions and environmental factors on the removal and treatment of PPCPs. The outcome will be the development of more sustainable WWTPs design and operation in terms of PPCPs removal.Read moreRead less

Drying sewage sludge using hot oil. The project seeks to investigate and develop an entirely new area of fundamental and applied research involving the process, mechanisms and kinetics of direct dehydration of sewage sludge by fry-drying in hot oil. Frying can be carried out as a drying process, though it not widely recognized or applied in this way, and has consequently not been exploited outside of the traditional food industries. It potentially provides a wide range of significant benefits ....Drying sewage sludge using hot oil. The project seeks to investigate and develop an entirely new area of fundamental and applied research involving the process, mechanisms and kinetics of direct dehydration of sewage sludge by fry-drying in hot oil. Frying can be carried out as a drying process, though it not widely recognized or applied in this way, and has consequently not been exploited outside of the traditional food industries. It potentially provides a wide range of significant benefits for sludge drying, including high efficiency and low costs, and produces a non-offensive product with a high energy value suitable for (renewable) power generation.Read moreRead less

A landfill cover that generates electricity: a Microbial Fuel Cell application. Landfills account for over two per cent of Australia’s greenhouse emissions, dominating emissions from waste and wastewater. Methane emissions are inherent to landfills because waste cannot be permanently sealed until a landfill cell is full. In this project, a microbial fuel cell (MFC) landfill cover will be developed as a means of achieving full biogas capture, from the time that waste is placed. The MFC cover syst ....A landfill cover that generates electricity: a Microbial Fuel Cell application. Landfills account for over two per cent of Australia’s greenhouse emissions, dominating emissions from waste and wastewater. Methane emissions are inherent to landfills because waste cannot be permanently sealed until a landfill cell is full. In this project, a microbial fuel cell (MFC) landfill cover will be developed as a means of achieving full biogas capture, from the time that waste is placed. The MFC cover system would consist of a relatively thin and deformable granular graphite layer colonised by current generating methane oxidising microorganisms, overlain by a proton exchange membrane and steel mesh as the anode layer. The MFC cover will provide the benefit of power generation as well as more complete greenhouse gas mitigation. Read moreRead less
