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 proposal addresses the core issues of energy and water, two highly critical resources in Australia as well as worldwide. Utilising our geographically-abundant solar energy and through designing novel photocatalytic systems, the proposed research provides an ultimately clean solution by efficiently harnessing and converting the solar energy to hydrogen while remediating wastewater. Given the high intensity and consistent solar output in Australia, such technology provides an almost ideal and sustainable outcome in terms of clean energy and water supply. Success in this area will place Australian researchers at the forefront of practical and functional photocatalytic technologiesRead moreRead less
Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants. Oil is extracted from oil shale by pyrolysing pre-dried crushed shale. Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones.

Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones. This aim of this proposal is to develop trickle filters to treat the sour water. The biofilms that develop in trickle filters are ideal for supporting slow growing microbial species. Research is needed to transfer native microorganisms in the oil shale desposit to the durable gravels that will be used in the filter.Read moreRead less

This project aims to develop a self contained skid-based transportable process for onsite destruction of per- and poly-fluroalkyl substances (PFAS) toxins at contaminated sites. The new technologies developed will span a range of application areas, although remediation of sites contaminated with PFAS by ongoing or legacy use of fire-fighting foams is a key target for this project. The process is expected to enable remediation of these sites by completely converting all toxins into safe products such as carbon dioxide and harmless salts. This project will deliver significant benefits, as the process is easily scalable and is intended to form the basis of a new or expanded remediation industry in Australia, resulting in manufacturing growth, job opportunities and significant impacts in terms of environmental safety and quality.Read moreRead less

Novel gas-liquid columns for liquefied natural gas (LNG) production. This project aims to design distillation and absorption columns, perhaps the most important unit operations in a liquefied natural gas (LNG) plant, and whose optimization is integral to overall performance of any LNG plant. This project will use 3D printers to rapidly prototype concepts of columns and their internals, and test them using flow characterization tools and numerical models. The final outcome of the project will be a set of designs of the columns, which should be more efficient, safer and cheaper to operate, and have smaller physical and environmental footprints, thus helping the Australian LNG industry to stay globally competitive.Read moreRead less
