Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously gen ....Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously generate nitric oxide, but not for extended periods of time. This project’s approach is significant because it avoids bacterial resistance to the nitric oxide treatment. Applications of this technology may include removing biofilms from environments such as water filtration devices and consumable medical surfaces.Read moreRead less
Ultrasound for control of cyanobacteria. Blue-green algae, also known as cyanobacteria, forms in drinking water supplies in Australia and can cause water-quality problems. Current methods to treat blue-green algae involve the use of Copper Sulphate, which is not an environmentally friendly compound. A potential alternative environmentally friendly water-treatment method involves the use of ultrasound to disrupt the cyanobacteria. The aim of this project is to determine the physical properties of ....Ultrasound for control of cyanobacteria.

There are many waste streams that need to be purified which degrade conventional membranes. This project with local company AMS aims to develop nano-porous metal membranes as a sustainable alternative to conventional membrane materials. Highly porous and ultra-thin metal membrane sheets with narrowly distributed nano-scale pores will be fabricated and functionalised to purify both model and industrial wastewaters. This intends to lead to the production of stronger, more versatile and chemically stable membrane materials that will exhibit longer lifespan and performance. The most significant outcome is expected to be low cost metal alloys with pores below the current 100 nm benchmark and assess their thermo-chemical stability.Read moreRead less

Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard. This project promotes improved organic pollutant removal and monitoring during advanced water treatment and will contribute to the National Research Priority goal, water - a critical resource, by providing the increased protection of receiving waters including rivers and seawater. Further, as very few studies consider the role of dissolved organic matter for organic pollutant fate in water reuse internationally, this project will help to advance Australia's position in science.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
Adsorption on activated alumina: mitigating fouling of water treatment processes caused by deposition of silica, organics and hardness ions. Coal seam gas offers tremendous economic potential but development of gas reserves will generate considerable quantities of saline water. This project will develop activated alumina technology for the removal of silica and organics from these waters to enable the industry to use evaporative technologies to reduce water volumes.
