Impact of rolling dynamic compaction. The project will lead to improved understanding and greater use of rolling dynamic compaction (RDC). RDC is a relatively new compaction technique that can be used to improve soft and derelict ground prior to the construction of roads, railways, subdivisions and structures. This project will also lead to greatly reduced ground improvement costs.

This project aims to develop a microbial self-healing bio-concrete to extend the service life of wastewater collection and treatment facilities. Water utilities worldwide struggle with asset management, because global warming and extreme weather age and corrode concrete infrastructure. This project will use microbially-induced calcium carbonate precipitation by bacteria to treat wastewater. The bacteria, added to bio-concrete, can fill cracks or reseal corroded areas by using organic substrates from wastewater to generate concrete, thus maintaining structural strength and preventing further damage. This project is expected to enhance the resilience and sustainability of wastewater infrastructure in ever more demanding environments.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

Investigation of chemical clogging in a permeable reactive barrier (PRB) installed for remediating groundwater from acid sulphate soils. Soil acidity is a major geo-environmental problem in coastal Australia, whereby acidified groundwater pollutes estuaries with catastrophic consequences on local aquaculture (e.g. fish, oyster and prawn farming) and agricultural industries. The project aims to optimise the design and performance of permeable reactive barriers (PRBs) utilising waste materials suc ....Investigation of chemical clogging in a permeable reactive barrier (PRB) installed for remediating groundwater from acid sulphate soils. Soil acidity is a major geo-environmental problem in coastal Australia, whereby acidified groundwater pollutes estuaries with catastrophic consequences on local aquaculture (e.g. fish, oyster and prawn farming) and agricultural industries. The project aims to optimise the design and performance of permeable reactive barriers (PRBs) utilising waste materials such as recycled concrete and oyster shells for neutralising groundwater acidity prior to discharge to waterways. The main research includes the study of potential clogging and fouling of these PRB materials due to chemical reactions and to develop a predictive tool for long-term PRB performance as a means of ground acidity alleviation.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

There is an increasing strain on scarce Australian water supplies and this requires effective water cycle management and protection of water resources as a whole. The proposed research aims to develop a model for the effective management of stormwater runoff through the investigation of confined filtration and infiltration devices in four separate locations. These confined systems will minimise the impacts of pollutant concentrations on native soils and groundwater. A model will be developed to predict required native soil permeabilities and residence times for adequate tertiary treatment in a variety of Australian conditions for non-potable reuse of runoff and/or groundwater recharge.Read moreRead less

Provision of safe drinking water treatment using sustainable technology which can be applied in rural locations and emergency situations is the main aim of this project. A hybrid membrane process will be combined with solar energy for the removal of pathogens and trace pollutants such as uranium, fluoride, arsenic, boron and nitrates. The technology will be designed for remote community situations and hence be robust and low in maintenance. Using solar energy is a challenge for trace contaminant removal as the operating conditions vary with the power fluctuations, which presents a substantially different situation to grid power connection.Read moreRead less
