This project aims to engineer unique particles containing defect-intensive surfaces which are designed to accelerate the catalytic ozonation of waters contaminated with pharmaceuticals and other recalcitrant pollutants. This will enable timely treatment of industrial waste water as well as sewerage treatment plant effluents using simple and cheap catalyst materials. Wet- and flame-based particle fabrication technologies paired with unique post-synthesis treatment strategies, including either a coupled hydrogenation-illumination approach or plasma exposure, will be implemented for defect manipulation so as to produce new cheaper, stable, and higher-performing catalysts for activating ozone to treat water containing pharmaceutical and endocrine disrupting micro-pollutants under different process conditions.Read moreRead less
Improving biological nitrogen removal by enhanced mixing in non-aerated bioreactors. Mixing has been identified as a key factor in achieving enhanced performance out of existing and upgraded bioreactors. There is currently a poor understanding of the relationship between non-ideal flow and performance in wastewater treatment bioreactors. The project will determine this relationship and subsequently use it to show how reactor performance can be improved, providing first criteria by which mixing c ....Improving biological nitrogen removal by enhanced mixing in non-aerated bioreactors.

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.

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.

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
