Cyanobacterial blooms in wastewater treatment plants impact on effluent quality and the utility of recycled water, posing a significant risk to the economy, the environment and public health. To understand the causes of cyanobacterial blooms in pond-based wastewater treatment plants and the risk they pose, this project will use the latest molecular techniques to examine how the microbial communities within these systems interact with each other and their surrounding environment to form blooms and produce toxins and other harmful metabolites. Such knowledge will inform risk assessment and provide strategies for the mitigation of future bloom events, improving the security of our increasingly valuable recycled water resources.Read moreRead less

It expects to address the concerns about the safety of stormwater harvesting via WSUD for all end-uses. It will generate new knowledge regarding the real time control and monitoring of WSUD, thus truly advancing the WUSD technology as emerging urban green infrastructure for reliable stormwater harvesting. Expected outcomes include next generation of WSUDs implemented with real time control techniques, as well as a suite of easy-to-measure surrogate parameters for real time water quality monitoring.Read moreRead less

This project aims to improve the resilience of Australian water supplies by building capacity in urban stormwater reuse. The project expects to address an industry-identified need to determine the suitability of urban lakes and wetlands for stormwater harvesting and develop chemical-sensory monitoring techniques to assess the quality of harvested water. Expected outcomes include the establishment of satellite-based remote sensing as a key technology for stormwater applications and the widespread use of improved techniques for monitoring odorants by the water industry. This should provide significant benefits by informing adaptive planning and infrastructure readiness at water utilities and guiding Australian policy on stormwater reuse.Read moreRead less
Urban flood modelling at speed and scale. Frequent floods in urban areas cause damages comparable to extreme floods. This is likely to intensify with future urbanisation and climate change. Although Water Sensitive Urban Design (WSUD) offers sustainable urban drainage solutions, there are no models that can select an optimal WSUD system to deliver on a set urban flood mitigation target.

Although Water Sensitive Urban Design (WSUD) offers sustainable urban drainage solutions, there are no models that can select an optimal WSUD system to deliver on a set urban flood mitigation target. The project aims to develop a new generation of fast urban flood models and the-first-of-its-kind WSUD planning tool to support industry and governments to effectively reduce the urban flooding damages. The project outcomes are also applicable for advancing early warning systems and real-time control of floods.Read moreRead less

This project aims to address an important limitation in the ability to monitor performance of advanced oxidation processes used to treat recycled water for drinking. The project will be conducted using a novel pilot system, designed to facilitate flexible operation and detailed monitoring. Through carefully designed experiments, observed operational parameters will be related to treatment performance for a range of contaminants. An expected outcome is the development of a framework to provide validation of process performance relationships and ongoing performance monitoring for use by water utilities and regulatory agencies that oversee their operations. This highly practical framework for validation and performance monitoring of an advanced water treatment process should result in improved viability of water recycling projects, increased urban water supply security and enhanced protection of public health.Read moreRead less

The majority of existing water treatment technologies are unable to remove PFAS to the desired extent, are prohibitively expensive or are only useful for a very limited lifespan. This project is expected to develop a new treatment technology with the ability to completely defluorinate PFAS, treat significant water quantities and help address many of the pressing concerns facing water treatment operators. This technology is also scalable, and can potentially be used to treat significant quantities of contaminated water.Read moreRead less

Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less

Summary
Multifunctional polymers for combined algal inactivation and flocculation. Algal cells are harmful because they produce toxins and other undesirable metabolites. So, they are killed, aggregated, and separated from the water in distinct steps. Cell killing and aggregation are achieved via chemical dosing, which damages the cells and releases undesirable compounds. The aim is to develop multifunctional polymers that can simultaneously kill and aggregate the cells without causing cell damage.

So, they are killed, aggregated, and separated from the water in distinct steps. Cell killing and aggregation are achieved via chemical dosing, which damages the cells and releases undesirable compounds. The aim is to develop multifunctional polymers that can simultaneously kill and aggregate the cells without causing cell damage. Additionally, this project provides insight into the mechanisms of polymer-induced cell damage and death that will be used to improve existing treatment methods. By combining treatment steps, chemical demand and costs will decrease, while there will be an increase in sustainability and benefits to the Australian water industry.Read moreRead less
