Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smal ....Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smaller systems at source. This will enable greater reliability of localised treatment, which will reduce pumping requirements and decrease both cost and carbon emissions. Read moreRead less

Development of a Novel Photoelectrochemical Method for Ultra-sensitive and Selective Determination of Organic Pollutants.

Rapidly deteriorating environmental conditions have caused worldwide fresh water shortage problems. For Australia, this is an urgent issue due to our limited fresh water resources. Globally, all levels of governments and legislative authorities have attempted to adopt stricter environmental legislation and better water resource management practice to address these urgent problems. However, these priorities cannot be achieved until large scale and accurate environmental data are available. The success of the project would result in a new environmental monitoring system capable of online, real-time monitoring of environmental water quality, which will directly benefit water resource management practice in Australia.

Nanostructures of Titanium Dioxide and Titanates by Wet-chemistry. One-dimensional (1D) nanoparticulates of titanium dioxide (TiO2) and titanate synthesized by wet-chemistry approaches are new advanced materials of unusual properties. This project will investigate the formation and phase transition mechanism of these 1D particulates by various techniques.

One-dimensional (1D) nanoparticulates of titanium dioxide (TiO2) and titanate synthesized by wet-chemistry approaches are new advanced materials of unusual properties. This project will investigate the formation and phase transition mechanism of these 1D particulates by various techniques. With such knowledge, we can effectively control the morphology on a scale of nanometers, and tailor the energy gap of these materials. This will significantly influence the photosemiconductive photocatalytic and lithium ions insertion behaviours of the particles so that advanced materials for solar energy conversion, photocatalysts for decomposing organic pollutants in environment, eletrode materials of lithium batteries can be developed.Read moreRead less

Reducing export of acid sulfate soil products (particularly iron, aluminium, phosphorus, and organic carbon) as contaminants to coastal waters. Current Australian management of acid sulfate soils (ASS) emphasises the reduction of acidity in floodplain drainage. However this acidity is mainly from the dissolved metals, which can be increased by some management techniques. Dissolved metals can be biotoxic or encourage harmful coastal phytoplankton.

Current Australian management of acid sulfate soils (ASS) emphasises the reduction of acidity in floodplain drainage. However this acidity is mainly from the dissolved metals, which can be increased by some management techniques. Dissolved metals can be biotoxic or encourage harmful coastal phytoplankton. Organic metal complexes can increase metal transport but shading of soil and drain surfaces, and constructed wetlands offers a new management tool. Our research aims to reduce transport to coastal waters of these ASS products. A sustainable Australian coast requires that improvement of ASS floodplains must not be at the environmental expense of coastal waters. Read moreRead less

Towards a Molecular-Scale Understanding of Sorption of Organic Pollutants to Soil. The toxicity, mobility and persistence of organic pollutants in soils are in large part controlled by their sorption to soil organic matter. The chemical nature or quality of the organic matter affects not only the amount of chemical sorbed, but also the reversibility of sorption and the rate of sorption and desorption. Until now, only bulk measures of soil organic matter chemistry have been considered in sorption ....Towards a Molecular-Scale Understanding of Sorption of Organic Pollutants to Soil.

The chemical nature or quality of the organic matter affects not only the amount of chemical sorbed, but also the reversibility of sorption and the rate of sorption and desorption. Until now, only bulk measures of soil organic matter chemistry have been considered in sorption studies. This project introduces novel spectroscopic techniques that for the first time identify the chemical environment of sorbed molecules at the molecular scale. This will enable better prediction of pollutant transport and degradation.Read moreRead less
