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

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

Sustainability of water and wastewater treatment chemicals. In recent years, the environmental design and management of water and wastewater treatment facilities has broadened from consideration of water quality outcomes to include the environmental consequences of energy and material inputs. This has produced nationally agreed approaches to estimating greenhouse gas emissions from power consumption, but for important chemical additives analysts are forced to work with low-quality estimated dat ....Sustainability of water and wastewater treatment chemicals. In recent years, the environmental design and management of water and wastewater treatment facilities has broadened from consideration of water quality outcomes to include the environmental consequences of energy and material inputs. This has produced nationally agreed approaches to estimating greenhouse gas emissions from power consumption, but for important chemical additives analysts are forced to work with low-quality estimated data. In a time when society wants to account for the 'carbon-footprint' of decisions and more broadly consider the resources used and emissions produced by industry, this research will make this quantitatively possible for chemicals used in water and wastewater treatment.Read moreRead less

Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems. While chloramine delivers microbiologically safe drinking water in warmer climates and in long distribution systems, it is largely unpredictable, costs water utilities millions of dollars annually, and has uncertain benefits. This project’s control system will be guided by quantitative models formulated from multi-pronged, fundamental experiments. The project will quantify microbial chloramine decay and determine mechanisms to increase predictability. The project will develop and demonstrate a real-time control technology which delivered microbiologically safe, cost-efficient drinking water to people in warmer climates, despite warming climate and increasing population.Read moreRead less

Advancing water pollution emissions modelling in cities of the future. This project aims to advance stormwater pollution modelling and enhance its link with urban development. Management of stormwater pollution by industry often results in inadequate strategies and, crucially, sub-optimal financial investments. Since this is unlikely to improve in light of urban growth and climate change, addressing decade-old pollution modelling knowledge gaps and the lack of a multidisciplinary approach to stormwater pollution management is urgent. The anticipated outcome is a modelling tool which industry can use to manage stormwater pollution in changing cities through smarter and economic technology and policy.Read moreRead less
Optimal trade-offs for managing environmental water in inland wetlands. This project aims to optimise long-term water trade-offs in inland wetlands on managed catchments, without compromising their environmental value.

This project aims to optimise long-term water trade-offs in inland wetlands on managed catchments, without compromising their environmental value. These managed wetlands compete for water allocations with irrigation and other uses. Realistic predictions of wetland status will be achieved through the development and integration of an ecohydrological model and a water management decisions model. Application of the tools will improve existing decision support models to help analyse the effects of individual local management decisions on the long-term evolution of the system and the effects of changes in operation policies and climate over the long term. The project will provide critical new information for the improved prediction of wetlands evolution and as a consequence better management.Read moreRead less

The project will aim to collate data and map base-level distribution patterns of molecular and microbial markers of human sewage and natural/agricultural contamination with reference to diurnal and seasonal fluctuations. These data will then be used to develop decision support systems that predict contaminant dispersion and identify high-risk contamination sources. The diurnal collection of data is expected to show significant variations in the measured parameters associated with time of day, light intensity and temperature. Mapping of the sewage and nutrient loads throughout the year will provide base line data for identifying potential hotspots for targeting system upgrades or improved management programs.Read moreRead less
