This project aims at improving plant efficiency and safety to a world's best level for the Ethylene Oxide (EO) plant of Huntsman Corporation Australia (HCA). EO is a key chemical intermediate for making polyesters (clothing, PET bottles, insulation) and surfactants. To remain globally competitive, it is essential to improve the efficiency of the plant, which has a small capacity and supports important Australian markets. The goals will be achieved by developing advanced operational and control strategies (through computer modeling, process optimisation and intelligent systems approach), which will assist in better understanding the process and in providing optimal HCA plant operation.Read moreRead less

Programming anisotropy into responsive soft materials. The project aims to generate viscoelastic soft materials with programmable anisotropy using aqueous suspensions of colloidal rods that have tunable surface coatings. The project expects to generate new knowledge in the rheology and structural characteristics of this unique class of materials.

The project aims to generate viscoelastic soft materials with programmable anisotropy using aqueous suspensions of colloidal rods that have tunable surface coatings. The project expects to generate new knowledge in the rheology and structural characteristics of this unique class of materials. A key innovation is the use of charge-directed polymer self-assembly to control colloidal interactions, suspension rheology and phase behaviour. The intended outcome is spatial control over the orientation of nanostructures, potentially mimicking the structural hierarchy found in nature. This should provide significant benefits to the creation of viscoelastic materials with complex rheology as well as structural, mechanical and optical heterogeneity.Read moreRead less
Adsorption and Removal of Trace Organic Compounds by Membrane Processes used in Water Treatment and Wastewater Recycling. Recycling of municipal wastewaters is of growing importance as a resource-conservation and environmental-protection measure in Australia. A major impediment to increased rates of water recycling is a lack of knowledge regarding the presence, fate and removal of key trace organic compounds. Among these key contaminants are pharmaceutically active compounds (PhACs) and steroid ....Adsorption and Removal of Trace Organic Compounds by Membrane Processes used in Water Treatment and Wastewater Recycling. Recycling of municipal wastewaters is of growing importance as a resource-conservation and environmental-protection measure in Australia. A major impediment to increased rates of water recycling is a lack of knowledge regarding the presence, fate and removal of key trace organic compounds. Among these key contaminants are pharmaceutically active compounds (PhACs) and steroid hormones. This research will lead to a thorough understanding of the mechanisms involved with the removal of these compounds by membrane treatment applications. Major benefits will be enhanced ability to undertake risk management and a lowering of costs associated with full-scale water treatment applications.Read moreRead less

To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are likely to be derived from the application of advanced engineering principles to this complex system. This project will integrate advanced CFD modelling and control principles for the design and operation of membrane systems in order to develop fundamental understanding that should lead to significant process improvements.Read moreRead less
Impact of Fouling on Retention of Contaminants in Electrodialysis for Brackish Water and Wastewater Applications. Water desalination and water recycling are both of utmost importance in the current global water crisis. Reverse osmosis is a commonly used process in both areas but this process has two main limitations (1) it is limited in water recovery by the concentration of salts, and (2) it produces a relatively large amount of concentrates that require disposal.

Water desalination and water recycling are both of utmost importance in the current global water crisis. Reverse osmosis is a commonly used process in both areas but this process has two main limitations (1) it is limited in water recovery by the concentration of salts, and (2) it produces a relatively large amount of concentrates that require disposal. Using electrodialysis to treat such concentrates will decrease the salinity problem caused by disposal and also increase the water efficiency of the treatment process. In this research project the potential performance limitations fouling and micropollutant removal will be investigated and hence the performance improved.Read moreRead less
Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams ....Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams will enhance the health of receiving water bodies and reduce the risk of increased build up of contaminants if wastes are recycled into wastewater treatment plants. New ways to treat such contaminants will be explored, the efficiency and cost evaluated in the broader water cycle and sustainability framework.Read moreRead less
