It is recognised worldwide that fouling is a major impediment in operation of Reverse Osmosis units used for production, purification and treatment of water. This project is aimed at studying pre-treatment options for composite fouling which is the main type of fouling present in RO units by using both model feed systems and actual field water. The project outcomes are to understand and develop pre-treatment strategies and to use those to develop a hybrid pre-treatment technology. This project will significantly impact water production in general and its outcomes will have far-reaching implications in treatment of water both within Australia and globally.Read moreRead less
The Boron Rejection by RO Membranes in presence of Calcium Carbonate and Magnesium Hydroxide. Water scarcity in various parts of the world demands the use of available saline waters for production of potable water. Reverse Osmosis membranes have been used as a means of achieving this objective. Fouling is a major impediment in operation of reverse osmosis units. The project aims to study boron removal by RO under high pH which increases the boron rejection but at the same time exacerbates compos ....The Boron Rejection by RO Membranes in presence of Calcium Carbonate and Magnesium Hydroxide. Water scarcity in various parts of the world demands the use of available saline waters for production of potable water. Reverse Osmosis membranes have been used as a means of achieving this objective. Fouling is a major impediment in operation of reverse osmosis units. The project aims to study boron removal by RO under high pH which increases the boron rejection but at the same time exacerbates composite fouling by calcium carbonate and magnesium hydroxide. Optimum pH for boron rejection will be determined and propensity of calcium carbonate and magnesium hydroxide at that pH range will be evaluated.Read moreRead less
Gas-phase and catalytic reaction of halons under reducing conditions. Halons are ozone-depleting substances, but their use continues in most countries. This project pursues techniques to convert, rather than destroy, halons into benign and useful products. The aims of this project are to gain a fundamental understanding of the reactions of the most commonly used halons, 1301, 1211 and 2402, and perform a detailed examination of catalytic processes for conversion of halons to HFCs. The primary ....Gas-phase and catalytic reaction of halons under reducing conditions. Halons are ozone-depleting substances, but their use continues in most countries.

The aims of this project are to gain a fundamental understanding of the reactions of the most commonly used halons, 1301, 1211 and 2402, and perform a detailed examination of catalytic processes for conversion of halons to HFCs. The primary outcome from the study will be the development of a process specifically designed to convert halons into useful products. This will assist with efforts to phase out continued halon use.Read moreRead less
Transformation of halons and CFC to valuable products through their reaction with methane. Halons and CFCs are well known as ozone depleting substances (ODS). This project pursues the development of a novel process to transform stockpiles of halons and CFCs into vinylidene difluoride (C2H2F2). Vinylidene difluoride is a highly valued commodity, used in the synthesis of heat resistant materials.

Halons and CFCs are well known as ozone depleting substances (ODS). This project pursues the development of a novel process to transform stockpiles of halons and CFCs into vinylidene difluoride (C2H2F2). Vinylidene difluoride is a highly valued commodity, used in the synthesis of heat resistant materials. The primary aim of this research is to gain understanding of the role of catalysts during conversion of CFC 12 and halon 1211 into the desired reaction product. The signifigance of the project is that it will facilitate development of a process for non-destructive treatment of ozone depleting substances. The major outcome of the proposed research is it will lay the technical foundation for the development of an energy efficient process to convert rather than destroy these ODS.Read moreRead less
Establishing the relations between starch nano- and mesostructure and macroscopic physical properties. Starch is the major energy component within human diets, and the most abundant polymer that can be readily extracted from annual crop plants, leading to many actual and potential industrial applications. There are major opportunities to optimise the nutritional value of starches in the human diet, and to enhance the properties of extracted starches as renewable alternatives to petrochemical pol ....Establishing the relations between starch nano- and mesostructure and macroscopic physical properties. Starch is the major energy component within human diets, and the most abundant polymer that can be readily extracted from annual crop plants, leading to many actual and potential industrial applications. There are major opportunities to optimise the nutritional value of starches in the human diet, and to enhance the properties of extracted starches as renewable alternatives to petrochemical polymers. This project will open up our understanding of the structure of starch polymers and show how this relates to important properties such as enzyme digestibility rates, leading to new opportunities for public health and commercial benefits.Read moreRead less
Biosynthesis of multiple-nonmetal codoped titania nanoparticles for visible light photocatalysis. Nano-photocatalysts' are particles of very small size that can degrade organic wastes and harmful microorganisms, when exposed to light. Titania is the most commonly used photocatalyst, but the limitation with existing titania is that it is mainly active in ultraviolet (UV) light. UV-light cannot be used for indoor applications because UV is mutagenic and causes cancer.

Titania is the most commonly used photocatalyst, but the limitation with existing titania is that it is mainly active in ultraviolet (UV) light. UV-light cannot be used for indoor applications because UV is mutagenic and causes cancer. This project will use an eco-friendly approach to develop novel titania nanoparticles, which will be active in visible light. Success will lead to new options in the management of our organic wastes and wastewaters (global problems), plant disease control, clean clinical surroundings, and add value to our day-to-day products like self-cleaning windows, and textiles.Read moreRead less
