Water is a critical resource for societies worldwide and Australia is one of the driest nations on Earth. Options to treat ‘used’ or lower quality waters for reuse are becoming a necessity. This project aims to implement advanced nanotechnology solutions to improve performance characteristics of widely adopted water treatment membranes, which have the potential to reduce water treatment costs in Australia. This is made possible by the collaboration with Australia's largest manufacturer of water treatment membranes. The outcomes will lead towards a lower maintenance water treatment technology available to communities, at lower cost. The application of such a technology will span from local small scale to major installations worldwide.Read moreRead less

This will produce economic and social returns to the community through improved water policies in the following areas: urban-rural water alloc ....Combining hydrological information with a multi-regional, computable general equilibrium model. The model to be created will combine a unique amount of economic detail at the statistical division level with hydrological detail. Users will obtain better estimates than previously available on the regional and industrial impacts of different water scenarios. This will produce economic and social returns to the community through improved water policies in the following areas: urban-rural water allocation; climate change impact assessment; water reform and water trading; and the economic impacts of meeting environmental objectives. The model will thus provide a path-breaking tool for examining issues arising from COAG reforms and broader policy goals. Read moreRead less
Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smal ....Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smaller systems at source. This will enable greater reliability of localised treatment, which will reduce pumping requirements and decrease both cost and carbon emissions. Read moreRead less
Microbial Ecology and Control of Foaming in Anaerobic Digesters. One of the world's most common treatments of biosolids (product of wastewater treatment), anaerobic digestion often suffers from accumulation of biological foam. This foam hinders treatment, personnel health and safety, legal requirements for environmental protection are jeopardised and attempts to control digester foaming are costly. There is a clear lack of knowledge about the organisms involved and causes, therefore no informe ....Microbial Ecology and Control of Foaming in Anaerobic Digesters. One of the world's most common treatments of biosolids (product of wastewater treatment), anaerobic digestion often suffers from accumulation of biological foam. This foam hinders treatment, personnel health and safety, legal requirements for environmental protection are jeopardised and attempts to control digester foaming are costly. There is a clear lack of knowledge about the organisms involved and causes, therefore no informed solutions exist. Molecular DNA techniques, 16SrDNA sequencing and DGGE, will assist in deciphering causes and organisms involved. Research outcomes will present environmental, legal and economical acceptable control strategies for digester foaming to the waste management and water industries.Read moreRead less

Water managers around Australia are currently considering various strategies to deal with water shortages. Many of these management actions have potential to impact water quality, through altering the nutrient balance within reservoirs and hence affecting nutrients available for cyanobacteria. Cyanobacteria blooms pose an increasing threat to water supplies, with economic, social and environmental costs of $150M pa in Australia. The project will provide tools to water quality managers to assess how changes to subtropical reservoirs, such as water recycling, catchment land-use changes and increased drawdown are likely to affect nutrient budgets and cyanobacteria blooms.Read moreRead less

Groundwater in the SE region of SA is a valuable resource. The South East Catchment Water Management Board is responsible for planning sustainable management of these resources. The Board seeks to discover whether any marine ecosystems are dependent upon these groundwater resources, to inform their water-allocation planning decisions. This research combines field-based marine ecology with groundwater hydrology to assess the influence of groundwater outflow upon small estuaries, sandy beaches and lagoonal seagrass meadows that exist along the coastline from Kingston SE to the Victorian border. Our multidisciplinary approach will set a benchmark nationally and internationally for such applied research.Read moreRead less
Environmental drivers for production of the toxin, cylindrospermopsin, by the cyanobacterium Cylindrospermopsis raciborskii. Water authorities spend significant resources to monitor and control algal blooms. A significant part of this is monitoring freshwater toxic algal blooms that can impact on drinking water and recreational uses. One of the difficulties in monitoring blooms is that the toxin content of individual species can vary considerably. It is unclear whether this is caused by changes ....Environmental drivers for production of the toxin, cylindrospermopsin, by the cyanobacterium Cylindrospermopsis raciborskii. Water authorities spend significant resources to monitor and control algal blooms. A significant part of this is monitoring freshwater toxic algal blooms that can impact on drinking water and recreational uses. One of the difficulties in monitoring blooms is that the toxin content of individual species can vary considerably. It is unclear whether this is caused by changes in environmental conditions, i.e. nutrient, light, temperature. This project would provide the link between environmental conditions and toxin production to improve the ability to predict and monitor toxin production.Read moreRead less
