On-line monitoring of cyanobacteria to predict coagulant doses and powdered activated carbon application in water treatment. Cyanobacteria, more commonly known as blue-green algae, can impact water quality by releasing toxins that can be harmful to human health and imparting unpleasant taste and odours to the water. This project will support the water industry in managing these risks by providing a rapid, on-line tool to assist in their removal during water treatment.
Network Calming - Using Smart Sensors to Improve Water Asset Performance. Recent high-frequency monitoring in water distribution networks (WDNs) shows that pressure perturbations are significantly more dramatic than expected and cause pipe failures with highly disruptive consequences. This project aims to hydraulically calm WDNs to improve their performance, informed by smart sensors. The project will generate insightful knowledge of the hydraulic behaviour of real WDNs. The outcomes will be new ....Network Calming - Using Smart Sensors to Improve Water Asset Performance. Recent high-frequency monitoring in water distribution networks (WDNs) shows that pressure perturbations are significantly more dramatic than expected and cause pipe failures with highly disruptive consequences. This project aims to hydraulically calm WDNs to improve their performance, informed by smart sensors. The project will generate insightful knowledge of the hydraulic behaviour of real WDNs. The outcomes will be new strategies to identify, eliminate and suppress harmful pressure perturbations, leading to a reduced burst rate, extended asset life, improved system operation and advanced design principles. The resultant sustainable water assets provide significant economic and environmental benefits to the water industry and society.Read moreRead less
Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will ....Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will consider silica and silica-rich nanoparticles in concert with cations and organics, with the aim of better managing cations so to facilitate nanoparticle lubrication. Project outcomes may include more productive use of assets, improved pre-treatment infrastructure to support reverse osmosis operation, and the environmental benefits of reduced chemical waste and increased water recovery.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.

Achieving Nitrite Shunt For Mainstream Sewage Treatment Using Human Waste. This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introduc ....Achieving Nitrite Shunt For Mainstream Sewage Treatment Using Human Waste. This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introducing a novel technology that innovatively harnesses a human waste, the project expects to remove the barrier. Expected outcomes will support the transformation of sewage treatment plants into net-zero energy generators. This should provide economic, environmental and energy benefits for Australia’s water and energy sectors.Read moreRead less
Sewer Monitoring and Management in the Digital Era. Overflow, flooding, corrosion, and odorous emissions are persistent issues for utilities managing sewers. Current sewer maintenance is reactive, and focuses on solving problems in local networks, despite that optimal solutions require a system-wide approach.

This project aims to produce new knowledge for developing ozone nanobubbles as a technological option for the water industry where commercially suitable technologies are unavailable. Australian water utilities have identified two key challenges: destruction of micropollutants and natural organic matter in recycled and reservoir water, respectively. New knowledge from the project will allow these water utilities to utilise the extraordinary properties of nanobubbles and the strong oxidation capability of ozone for effective and energy efficient water treatment. Tech-transfer to the industry is guaranteed through a scientifically designed pilot plant for benchmarking against the current state of the art ozonation process and reverse osmosis.Read moreRead less

This project aims to improve understanding of the contribution of urban waterways to enhanced liveability in cities. Australia needs better water resource management and the rapid growth of Australia’s cities places increased importance on managing natural assets in metropolitan areas. The project focuses on clarifying the link between the benefits of waterways and the measurement techniques used by economists, which in turn inform management choices. The project aims to fill an important gap between the psychology and economics disciplines and outputs should significantly improve the way waterways are valued and managed. This is intended to offer benefits for urban residents and to improve the methodologies used for environmental valuation.Read moreRead less
Biofilm-based solution for cost-effective high-quality drinking water. Approximately 90% of the drinking water in Australia is sourced from surface water bodies, which are naturally rich in nutrients and organic matter. This leads to the growth of cyanobacteria, which are known to be a major cause of taste and odour compounds and cyanotoxins. Climate change is causing increased cyanobacterial growth due to higher temperatures, exacerbating this existing challenge to water utilities.
