Australia's remote communities, including agricultural and Indigenous communities, are an important part of Australian society and a significant contributor to the Australian economy, yet their access to cheap, secure, reliable and clean energy remains a significant challenge. Building on recent scientific advancement in anaerobic digestion, this project will develop a new technology for biogas production using locally available resources such as green waste and animal droppings. The outcome of this project will provide clean energy services to regional communities while minimising greenhouse gas emissions associated with waste disposal and thus contribute to the development of an environmentally sustainable Australia.Read moreRead less
Desalting reclaimed wastewater to safeguard Virginia's horticultural industries. 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 ....Desalting reclaimed wastewater to safeguard Virginia's horticultural industries. 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
Desalination Options for Metropolitan Adelaide's Water Supply & Implications for Water Resource Allocation to Regional Communities. This project will present a proposal for water supply augmentation by desalination to alleviate rising salinity concerns and supply uncertainty of River Murray water supplies to metropolitan Adelaide in South Australia.

This project will present a proposal for water supply augmentation by desalination to alleviate rising salinity concerns and supply uncertainty of River Murray water supplies to metropolitan Adelaide in South Australia. It will investigate the feasibility of desalination options available and their consequences for regional agriculture and industry that rely on river water from metropolitan water supply pipelines for their economic survival. The project outcomes will have significant implications for government water policies and private and public sector water-infrastructure investment. It will be the first detailed study of large-scale municipal desalting costs under Australian conditions.Read moreRead less
Improving the Durability and Performance of Hollow Fibre Membranes with Nanocomposite and Inorganic/organic Hybrid Materials. Water is a critical resource for societies worldwide and Australia is one of the driest nations on Earth. Options to treat ‘used’ or lower quality waters for reuse are becoming a necessity. This project aims to implement advanced nanotechnology solutions to improve performance characteristics of widely adopted water treatment membranes, which have the potential to reduce ....Improving the Durability and Performance of Hollow Fibre Membranes with Nanocomposite and Inorganic/organic Hybrid Materials. Water is a critical resource for societies worldwide and Australia is one of the driest nations on Earth. Options to treat ‘used’ or lower quality waters for reuse are becoming a necessity. This project aims to implement advanced nanotechnology solutions to improve performance characteristics of widely adopted water treatment membranes, which have the potential to reduce water treatment costs in Australia. This is made possible by the collaboration with Australia's largest manufacturer of water treatment membranes. The outcomes will lead towards a lower maintenance water treatment technology available to communities, at lower cost. The application of such a technology will span from local small scale to major installations worldwide.Read moreRead less
Electrocoagulation as a low-cost option for the continuous treatment of highly polluted wastewater. Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users.

Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users. Detailed scoping work in 2005 has identified electrocoagulation as a technically simple and economically viable option for this industry sector. Our industry partner is part of a global multi-national corporation within which successful wastewater treatment technology will be rapidly exploited and exported. Read moreRead less
Development of a Model Relating Aggregate Properties with Aggregation Conditions for Design and Control Purposes. The project aims to understand the role of shear and other important parameters in the aggregation of nano- and micron-sized particles through fundamental studies on different particulate systems and shear environments.

The project aims to understand the role of shear and other important parameters in the aggregation of nano- and micron-sized particles through fundamental studies on different particulate systems and shear environments. The knowledge will be used to develop an engineering model relating the floc properties to system conditions, thus allowing the utilisation of experimental data to full-scale operations without eschewing their relevance. Project outcomes include a comprehensive guideline to set optimum conditions required to generate flocs with desirable properties for control and design purposes, with applicability extending from solid-liquid separation to nano-material synthesis, and various processes involving particle aggregation.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
