Hydrogen production from the anaerobic digestion of organic waste using a novel membrane. Solid organic waste is a potentially large, decentralized and sustainable source of hydrogen. The potential hydrogen yield from the anaerobic digestion of solid organic waste in Sydney alone could power over 750,000 passenger vehicles. Hydrogen is always generated in the digestion of organic material, but under natural conditions it is scavenged by methanogens. Recently developed silica membranes are sel ....Hydrogen production from the anaerobic digestion of organic waste using a novel membrane. Solid organic waste is a potentially large, decentralized and sustainable source of hydrogen. The potential hydrogen yield from the anaerobic digestion of solid organic waste in Sydney alone could power over 750,000 passenger vehicles. Hydrogen is always generated in the digestion of organic material, but under natural conditions it is scavenged by methanogens. Recently developed silica membranes are selectively and highly permeable to hydrogen, and these can be used to draw hydrogen from the digester. The digester will be run at high temperatures (>65oC) because this favours organisms that produce hydrogen over methanogens. Anaerobic digesters are well established in Europe and at least 3 municipal plants already exist in Australia.Read moreRead less
Optimising nanofiltration and reverse osmosis filtration processes for water recycling: effects of fouling and chemical cleaning on trace contaminant removal. In Australia, water recycling is considered a principal measure to manage the current ongoing water shortage and to better protect the environment.

However, there is very limited knowledge regarding the reliability of such processes in re ....Optimising nanofiltration and reverse osmosis filtration processes for water recycling: effects of fouling and chemical cleaning on trace contaminant removal. In Australia, water recycling is considered a principal measure to manage the current ongoing water shortage and to better protect the environment. Membrane filtration processes play important roles in the treatment of reclaimed municipal wastewater. However, there is very limited knowledge regarding the reliability of such processes in removing trace contaminants from recycled water, which may result in unintended health consequences. This research will lead to a comprehensive understanding of the removal process of such contaminants by membrane filtration. Consequently, the likely avenue of risk can be eliminated and the treatment process can be optimised to achieve economic savings and environmental protection.Read moreRead less
Optimising dissolved air flotation (DAF) for algae removal by bubble modification in drinking water and advanced wastewater systems. Algal blooms in potable water reservoirs and advanced wastewater treatment lagoons can impact the performance and economic viability of water treatment processes resulting in taste and odour episodes and the risk of algal toxins as well as causing further limitation to already stressed water resources in Australia. This project aims to develop an adaptation of the ....Optimising dissolved air flotation (DAF) for algae removal by bubble modification in drinking water and advanced wastewater systems. Algal blooms in potable water reservoirs and advanced wastewater treatment lagoons can impact the performance and economic viability of water treatment processes resulting in taste and odour episodes and the risk of algal toxins as well as causing further limitation to already stressed water resources in Australia. This project aims to develop an adaptation of the dissolved air flotation process that is already used for algae treatment that will provide a more robust, economic and sustainable barrier to algal cells in accordance with the Australian Drinking and Recycled Water Guidelines.Read moreRead less
Development of smart material for the adsorption of oil spills on roads. The cost of road fuel spills in both Australia and worldwide is enormous. The research objective is to develop an admixture suitable for the absorption/adsorption of fuel and oil from road spills. The material will be designed to be contained within a fabric. The innovation is the application of the admixture in the form of a carpet, which is designed as easily used, non-toxic, recyclable and environmentally friendly.

The innovation is the application of the admixture in the form of a carpet, which is designed as easily used, non-toxic, recyclable and environmentally friendly. The application is rapid. The successful development of the material has enormous economic benefits to Australia, providing a new industry with many employees. This new industry has the potential to bring great wealth to Australia.Read moreRead less
Optimising Decentralised Membrane Bioreactors for Water Reuse. Water is a critical resource in Australia and as pressures on water resources increase, water recycling has emerged as an important component of water management practises throughout Australia.

Water is a critical resource in Australia and as pressures on water resources increase, water recycling has emerged as an important component of water management practises throughout Australia. Decentralised wastewater treatment systems (or package plants) offer opportunities for water recycling in regional communities; however this application is limited by our understanding on the removal of contaminants of concern through these treatment systems. This project will assess the suitability and efficiency of decentralised membrane bioreactors (MBRs) for the removal of endocrine disrupting chemicals (EDCs), pharmaceutically active compounds (PhACs) and pathogens in accordance with the 2006 National Guidelines for Water Recycling.Read moreRead less
The Effective Treatment of Hot Dip Galvanizing Effluent Streams. Hot Dip galvanizing effluent represents a significant environmental hazard. This wastewater is currently trucked offsite and treated by contractors to precipitate a heavy metal sludge that is disposed of through landfill.

Hot Dip galvanizing effluent represents a significant environmental hazard. This wastewater is currently trucked offsite and treated by contractors to precipitate a heavy metal sludge that is disposed of through landfill. Industrial Galvanisers, as the largest hot dip galvanizing company within Australia, are keen to eliminate this hazard. We will consider the use of an innovative membrane based process for this purpose; to recover valuable zinc and iron compounds from the effluent and allow the water to be re-utilised. If successful, this project will lead to a pilot plant wastewater treatment plant being constructed at an Industrial Galvanizers site.Read moreRead less
The Treatment Of Galvanizing Wastewater: Delivering An Environmentally And Economically Sustainable Approach. This project will investigate a process to treat wastewater from industrial galvanizing sites around Australia. When implemented, the process will substantially reduce the consumption of acid and fresh water at these sites. Further, the process will recover the zinc content of the wastewater in a saleable form and can also generate ferric chloride for sale as a water treatment chemical. ....The Treatment Of Galvanizing Wastewater: Delivering An Environmentally And Economically Sustainable Approach.

When implemented, the process will substantially reduce the consumption of acid and fresh water at these sites. Further, the process will recover the zinc content of the wastewater in a saleable form and can also generate ferric chloride for sale as a water treatment chemical. The quantity of heavy metals disposed to landfill will also be dramatically reduced. Scientific knowledge of multicomponent liquid-liquid equilibria will be of value to a wider range of solvent extraction processes including zinc and copper metal refining.Read moreRead less
