Optimising Fouling Control in Membrane Bioreactors. Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs.

Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs. The proposal aims to reduce the costs of fouling control by understanding the optimal conditions to remove these depositions and improve the design of MBR modules, operating conditions and shear delivery in the membrane system.Read moreRead less

Compared with conventional technologies for waste heat recovery, GRANEX cycle offers higher thermal efficiencies, better economics and a greater degree of robustness. If deployed ascross the country to recover even 10% of the nation's waste heat, it would reduce greenhouse emissions by 9 mega tonne which is roughly 1.6% of the annual national emissions.

Compared with conventional technologies for waste heat recovery, GRANEX cycle offers higher thermal efficiencies, better economics and a greater degree of robustness. If deployed ascross the country to recover even 10% of the nation's waste heat, it would reduce greenhouse emissions by 9 mega tonne which is roughly 1.6% of the annual national emissions. That is equivalent to the yearly CO2 emissions from 648,000 houses or 2 million cars. The proposed research will place Australia within the forefront of the research and development activities in the field of waste heat recovery and will clearly contribute to the Federal Government’s effort in the National Research Priority 1, An Environmentally Sustainable Australia.Read moreRead less

A methodology for the control of harmonics due to large distorting loads. The ideal electricity supply has a voltage of prescribed frequencey and value with a sinusoidal waveshape. Modern electronic equipment such as digital commuication equipment and automatic manufacturing lines draw non-sinusoidal currents which distort the voltage waveform. Electricity suppliers are responsible for limiting voltage distoration to levels set by national standards.

The ideal electricity supply has a voltage of prescribed frequencey and value with a sinusoidal waveshape. Modern electronic equipment such as digital commuication equipment and automatic manufacturing lines draw non-sinusoidal currents which distort the voltage waveform. Electricity suppliers are responsible for limiting voltage distoration to levels set by national standards. Techniques have been developed to allow them to determine the maximum level of current distortion to which a particular customer is entitled. This project will developand verify a method for determining if a particular customer exceeds that entitlement.Read moreRead less

As the demands for domestic and industrial water increasing in Australia and overseas, membrane bioreactors (MBR) offer an alternative for producing higher effluent quality wastewater compared to conventional processes. However, aeration costs used to remove fouling deposits (which reduce the operating performance) need to be further minimised. The proposal aims to study fundamental mechanisms involve in the deposition of foulant components by using model systems of polysaccharides, proteins and microbial cells and comparing these with real MBR systems. The effect of bubbling varied gas compositions (air/H2S ratios) a novel approach in this study will be investigated to prevent or remove foulants in MBR systems. Read moreRead less
