A novel process for removing phosphorus microbiologically from wastewater. Australia is a water limited continent, and its rivers and lakes are priceless assets, but because of climatic conditions, these are especially sensitive to blooms of 'blue green algae'. Some are highly toxic, and water containing them is unsuitable for most purposes. Current technology for P removal requires constructing complex plant configurations, and most of these operate unpredictably and unreliably. This project ....A novel process for removing phosphorus microbiologically from wastewater. Australia is a water limited continent, and its rivers and lakes are priceless assets, but because of climatic conditions, these are especially sensitive to blooms of 'blue green algae'. Some are highly toxic, and water containing them is unsuitable for most purposes. Current technology for P removal requires constructing complex plant configurations, and most of these operate unpredictably and unreliably. This project will develop and fully evaluate a revolutionarily different alternative with a fully aerobic system, capable of being added onto the end of a conventional treatment plant, making protection of rivers and streams simpler and more feasible.

Biocontrol of foaming in activated sludge plants with bacteriophages. Activated sludge systems are the most widely used processes for treating wastewater in Australia. Yet most eventually suffer from episodes of bulking and foaming, where high levels of biosolids leave the plant with the treated waste, representing serious pollution hazards. Attempts to solve these problems have met with limited success.The highly novel biocontrol method proposed here will provide a specific, environmentally fri ....Biocontrol of foaming in activated sludge plants with bacteriophages.

Microbiology of Autothermal Thermophilic Aerobic Digester (ATAD) Systems for Biosolids Disposal in Wastewater Treatment Systems. The disposal of biosolids from wastewater treatment plants is expensive and troublesome. ATAD systems utilise microbes and are claimed to overcome many of the problems of more conventional disposal methods. Two have been installed in plants in central Victoria. However, virtually nothing is known about their microbiology. The study will determine which microbial popula ....Microbiology of Autothermal Thermophilic Aerobic Digester (ATAD) Systems for Biosolids Disposal in Wastewater Treatment Systems. The disposal of biosolids from wastewater treatment plants is expensive and troublesome. ATAD systems utilise microbes and are claimed to overcome many of the problems of more conventional disposal methods. Two have been installed in plants in central Victoria. However, virtually nothing is known about their microbiology. The study will determine which microbial populations are present and responsible for biosolids digestion, how these populations might change with changing operational conditions, and whether these changes in populations relate to production of odors. This information will enable these digesters to be better managed and operated.Read moreRead less
