New approaches to the treatment of potable water in the presence of algal blooms. The processing of blue green algae rich waters and subsequent release of algal metabolites causes taste and odour problems and toxins that affect potable water safety. This project will define a preferred approach to the processing of these waters and provide quantitative analysis tools to help water authorities guarantee water quality and safety. The defined process routes and analysis procedures will also resul ....New approaches to the treatment of potable water in the presence of algal blooms. The processing of blue green algae rich waters and subsequent release of algal metabolites causes taste and odour problems and toxins that affect potable water safety. This project will define a preferred approach to the processing of these waters and provide quantitative analysis tools to help water authorities guarantee water quality and safety. The defined process routes and analysis procedures will also result in better water conservation (lower net water losses in processing). This will allow better regulation of water quality, safety and management by water authorities and improve consumer confidence in the potable water supply.Read moreRead less
Development of in Ground and on Site Technologies for Low Cost Metal Remediation of Remote Contaminated Sites. Australia has taken a leading role internationally in promoting environmental awareness and is committed to both tackling existing pollution and mitigating future hazards. The clean-up of contaminated Australian, Antarctic and sub-Antarctic sites is seen as a national priority and research into in-situ technologies is central to meeting established remediation goals.

Australia has taken a leading role internationally in promoting environmental awareness and is committed to both tackling existing pollution and mitigating future hazards. The clean-up of contaminated Australian, Antarctic and sub-Antarctic sites is seen as a national priority and research into in-situ technologies is central to meeting established remediation goals. Successful development of a low-cost in-ground remediation scheme will provide vital protection for remote Australian, Antarctic and sub-Antarctic areas. It will also do much to cement Australia as a global leader in environmental protection, offering as it does a generic remote regions metal contamination remediation solution.Read moreRead less

Virginia is a major horticultural region of South Australia undergoing rapid expansion. Groundwater resources are depleted and reclaimed sewage effluent from Adelaide is required for irrigation. Unfortunately, the effluent is frequently too saline. Large-scale desalting is being considered. A pilot-scale plant will be built to evaluate suitable desalting processes (e.g. reverse osmosis) for reducing the effluent's salt content. Original research will: (i) synthesize the best combination of technologies to produce effluent streams of varying salinity for matching different crop requirements; and (ii) optimise delivery and storage of effluent streams using new storage(s) and the region's multiple aquifer and surface storages.Read 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. This aim of thi ....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. 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
Fundamental Knowledge Generation of Organic Solid Waste-Microorganism Interactions. The management of organic solid waste is a major global environmental issue, exacerbated by increasing populations and urbanisation. However, there are biological processes (e.g. anaerobic composting) that show excellent potential as the solution to this global problem.

The management of organic solid waste is a major global environmental issue, exacerbated by increasing populations and urbanisation. However, there are biological processes (e.g. anaerobic composting) that show excellent potential as the solution to this global problem. We know that the rate-limiting step to biological organic solid waste degradation is the initial hydrolysis process carried out by microorganisms. We will study at a microscale the "organic solid waste surface-microorganism" interactions and compare data from digesters with the rumen which is a highly efficient model solid substrate digestion system. Our generated knowledge will be used in future practical applications.Read moreRead less
