Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its ....Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its beneficial use to enhance nitrogen removal, which is otherwise typically unsatisfactory due to the lack of organic carbon to support denitrification. The project will provide strong support to the Australian water industry in their endeavour to achieve energy- and carbon-neutral wastewater services.Read moreRead less
Novel disinfection to combat antibiotic resistance . Control of antimicrobial resistance in water is critical. Disinfection in water and wastewater treatment plants is a vital barrier against antibiotic resistant bacteria (ARB); however, it is less effective in controlling- and may even facilitate the spread of antibiotic resistance genes (ARGs).

Control of antimicrobial resistance in water is critical. Disinfection in water and wastewater treatment plants is a vital barrier against antibiotic resistant bacteria (ARB); however, it is less effective in controlling- and may even facilitate the spread of antibiotic resistance genes (ARGs). This project aims to comprehensively investigate the effectiveness of widely-used disinfection processes in controlling ARB/ARGs, determine the underlying mechanisms, and identify optimal treatment conditions. This project also aims to develop a novel, cost-effective and environmentally friendly disinfection process for efficient ARGs destruction, thus significantly strengthening Australia’s capacity to prevent the spread of antibiotic resistance.Read moreRead less

Modelling of Nitric Oxides and Carbon Monoxide Emissions from Bagasse-Fires Boilers. The project aims to develop computational models to predict emissions of nitric oxides and carbon monoxide from sugar-mill boilers burning bagasse. Bagasse combustion does not contribute to greenhouse gas emissions and clean and efficient combustion of this fuel has become very important for the sugar industry and for Australia.

The project aims to develop computational models to predict emissions of nitric oxides and carbon monoxide from sugar-mill boilers burning bagasse. Bagasse combustion does not contribute to greenhouse gas emissions and clean and efficient combustion of this fuel has become very important for the sugar industry and for Australia. The project combines the opportunity of direct boiler measurements by SRI with the modelling expertise at the University to develop combustion-kinetics models for these species. The models will be incorporated into the previously developed computational fluid dynamics - combustion code of the furnace to give the capability of emission prediction as a function of burner operating conditions and fuel parameters.Read moreRead less
Plasma-Catalytist Hybrid Process for Simultaneous Removal of NOx and SOx. Coal combustion provides over 80% of the electricity produced in Australia, with the power stations being major emitters of the pollutants NOx and SOx. This project will potentially lead to a new technology to simultaneously remove NOx and SOx in a single and economical process, eliminating the secondary waste streams that disadvantage current competing technologies. This will provide: significant environmental benefits f ....Plasma-Catalytist Hybrid Process for Simultaneous Removal of NOx and SOx.

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.

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 can be assessed, and second a systematic methodology for improving reactor performance by improving mixing.Read moreRead less
Iron and phosphorus recovery from ferric precipitation sludge. To minimise health risks and environmental pollution, water and wastewater treatment processes often use iron salts to eliminate phosphate and other pollutants. This generates large amounts of chemical sludge that is typically sent to landfill. The benefits of this new process will be the recovery of both the iron, which can be reused in the process, and the phosphate, which is a key component in fertiliser. Since phosphate is a limi ....Iron and phosphorus recovery from ferric precipitation sludge. To minimise health risks and environmental pollution, water and wastewater treatment processes often use iron salts to eliminate phosphate and other pollutants. This generates large amounts of chemical sludge that is typically sent to landfill. The benefits of this new process will be the recovery of both the iron, which can be reused in the process, and the phosphate, which is a key component in fertiliser. Since phosphate is a limited natural resource with an increasingly high value, the recovery and recycling of this critical element in food production is highly important. The process will also avoid a large part of the sludge production and will make the water treatment processes more cost-effective.Read moreRead less

Microbial fuel cells for nutrient recovery from source-separated urine. This project aims to reduce the strain on urban wastewater treatment plants by removing and recovering nutrients from water collected in residential and commercial buildings. Urban wastewater treatment plants in Australia are under pressure from increasing population and urbanisation, and there are also ever stricter environmental regulations on discharge of nutrients (mainly nitrogen and phosphorus) into receiving waters.

This project aims to reduce the strain on urban wastewater treatment plants by removing and recovering nutrients from water collected in residential and commercial buildings. Urban wastewater treatment plants in Australia are under pressure from increasing population and urbanisation, and there are also ever stricter environmental regulations on discharge of nutrients (mainly nitrogen and phosphorus) into receiving waters. With many plants operating close to capacity, water utilities may face large expenditure to increase the capacity of existing treatment facilities. This project proposes an alternative solution: decentralised removal and recovery of nutrients from urine separated at the source. It is planned that novel microbial fuel cell technology will be developed to deliver an economical solution, which will additionally generate valuable fertiliser as a by-product.Read moreRead less
