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
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
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. Globally, there is a united ....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. 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
Development of a photoelectrochemical system based on Titanium dioxide nanotubes/boron doped diamond heterojunction for online water quality monitoring. The reuse of purified recycled wastewater (PRW) creates an additional water supply source and improves the sustainability of the overall water resources.

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

This project aims to solve a critical issue of solar-steam desalination by fundamental research. The solar-steam desalination technology offers an ideal strategy to utilize solar light as the energy source for desalination and water purification to produce affordable clean water. Photothermal materials play a key role in the desalination system to convert sunlight to heat and subsequently evaporate the saline water to generate steam as clean water. However, salt crystallization on the photothermal material surfaces severely limits the performance of the materials and clean water production. Solving this problem could accelerate the commercialisation and application of this technology, which will benefit millions of people worldwide.Read moreRead less
Designing plasmon-enhanced photocatalysts for solar-driven water pollutant removal.

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

Fast stimuli-responsive polymer hydrogels as a new class of draw agent for forward osmosis desalination. The ability to extract fresh water from saline water can be important in areas such as desalination and other industrial applications. In this project new materials will be developed to perform this operation at a much lower energy cost than similar processes, whilst also improving the purity of the separated water.
