High performance multifunctional hierarchical structured membrane for water processing. The water processing industry is one of the most important economic sectors in Australia, though water scarcity is an economic limiting growth factor. The project targets at developing the next generation water processing technology affordable to residential consumption and applications in the industry and agriculture.
Development of advanced ceramic membranes: a robust solution to sustainable water treatment. Australia is one of the driest nations on Earth. While available fresh water supplies dwindle, options to treat 'used' water for reuse are gaining rapid popularity. Membranes are now state-of-the-art for water treatment, including all new desalination plants, but as they are polymeric based, they must be routinely cleaned with chemicals and replaced. The outcomes of this research will demonstrate innovat ....Development of advanced ceramic membranes: a robust solution to sustainable water treatment. Australia is one of the driest nations on Earth. While available fresh water supplies dwindle, options to treat 'used' water for reuse are gaining rapid popularity. Membranes are now state-of-the-art for water treatment, including all new desalination plants, but as they are polymeric based, they must be routinely cleaned with chemicals and replaced. The outcomes of this research will demonstrate innovative functional ceramic membranes which last longer and have lower requirement for cleaning chemicals and expert maintenance. This, in turn, will deliver water at lower cost and reduced environmental burden (chemical and membrane disposal), giving industry more sustainable solutions to treat water, which has now become an essential practice in society.Read moreRead less
Carbon nanotube fluidic channels for desalination - interplay of nanoscale confinement and electrostatics. Tiny tubes of carbon, ten thousand times smaller than human hair, allow water to pass through at extraordinary speed. This project aims to understand and improve their salt rejection properties using comprehensive experimental and theoretical approaches. This will provide the impetus and knowledge for developing advanced membranes for desalination
Composite conductive electrodes for low energy desalination. Good quality drinking water supply is a critical issue for water security particularly for inland regional and remote communities, where seawater desalination is not a feasible option.

The superior electrode materials are the key to achieve this goal. The water industry will use the information to assist their decision making for future water supply augmentation in regional communities. High capacity and lower energy forms of desalination are critical to ensuring desalinated water comes at an affordable price for the regional communities.Read moreRead less
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
Fabrication of High Performance Nanocomposite Photoanodes with Built-in Electron Transport Superhighway for Photoelectrocatalysis Applications. Worldwide, huge fresh water shortage problems force us to recycle/reuse water. For Australia, this is an urgent issue due to our limited fresh water resources. In recent years, rapidly diminishing fossil fuel supplies and dramatically accelerated global warming gives society no alternative but adopt renewable, clean energies.

Worldwide, huge fresh water shortage problems force us to recycle/reuse water. For Australia, this is an urgent issue due to our limited fresh water resources. In recent years, rapidly diminishing fossil fuel supplies and dramatically accelerated global warming gives society no alternative but adopt renewable, clean energies. Globally, there is a united front calling for action to address these problems. However, a practical solution to the issues can only be found when economically viable alternative technologies are developed. This project aims to tackle the biggest obstacle - the low sunlight conversion efficiency. The success of the project will result in economically viable water treatment and solar energy conversion technologies. Read moreRead less

The reuse of purified recycled wastewater (PRW) creates an additional water supply source and improves the sustainability of the overall water resources. This calls for online water quality monitoring systems to prevent potential water quality risk from organic contaminants in PRW and enable industries and government bodies to monitor and manage our water resources effectively. The success of the project would lead to a robust and reliable environmental monitoring system capable of online, real-time monitoring of organic pollutants and toxins, which will transform the existing water quality monitoring technology and directly benefit water resource management practice in Australia.Read moreRead less

The outcomes of this research aim to provide a unique opportunity for Australian researchers to become world leaders in the rapidly-emerging, energy-efficient forward osmosis technology which is very relevant not only to wastewater treatment, but also to desalination.Read moreRead less
Transistor-based sensor technology for fast, reliable and accurate in situ monitoring of recycled wastewater. Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand.

Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand. The greatest community and industry concerns over recycled water are quality assurance and relative cost. Ensuring quality requires monitoring of contaminants, yet no single real-time technology exists to measure the myriad of potential contaminants. This project will develop technology using AlGaN/GaN-based transistors, sensitised to different contaminants, enabling multi-analyte real-time sensor arrays. In situ monitoring systems based on such arrays will be fast, accurate, reliable, low-cost, and applicable to a broad variety of water recycling projects.Read moreRead less
