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.

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.

New technology to enable membrane desalination of wastewater treatment effluent will be developed to provide secure reliable water supplies for Australian (and international) urban and regional communities. Application of the technology to Western Treatment Plant at Werribee will provide up to 10 gigalitres/year of recycled water to the local agricultural, business and tourism precincts. The economy, community and environment will benefit due to reduced use of potable, river and ground water. Wide application of this technology to wastewater and brackish water will lead to similar benefits and an environmentally sustainable Australia.

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

Summary
The proposed expansion of salmon farming to new sites in south eastern Tasmania earlier this year has already elicited opposition from some neighbouring residents, wild abalone fishers and environmental groups, which has been well displayed in the media. One of their major concerns is lack of information on whether salmon farms are affecting intertidal and subtidal macroalgae, and no ongoing monitoring of these habitats.

One of their major concerns is lack of information on whether salmon farms are affecting intertidal and subtidal macroalgae, and no ongoing monitoring of these habitats. This highlights the importance of repeating the survey eleven years later to assess changes in intertidal macroalgal abundance and species composition around salmon farms.
Drones are increasingly being used to record agricultural environments, including salmon farms. However, methods to quantitatively assess coastal environmental change using drones, such as macroalgal distribution and abundance have not been assessed. The effectiveness of this technique to monitor salmon farms is needed to maximise usage of this data and before it can be incorporated into monitoring programs.
This project will provide information important to several FRDC Strategic Priority Areas. • Program 1: Environment: Themes 2 and 4: Habitat and Ecosystem Protection and Ecologically Sustainable Development, especially providing information to the community to demonstrate improvements in the aquaculture industry’s environmental performance and quantifying the environmental carrying capacity of aquaculture operations. • Program 2: Industry: Theme 6 and 7: Resource Access and Allocation, and Production, Growth and Profitability, especially increasing knowledge among diverse groups of stakeholders about each other’s expectations for resource access and allocation, and increase and diversify opportunities for the aquaculture sector. • Program 3: Communities: Theme 10: Resilient and Supportive Communities, especially understanding and influencing the community perceptions about the fishing and aquaculture industry and improving interactions between them, and increasing the community’s capacity to accept and incorporate higher levels of aquaculture activity.
Objectives: 1. To repeat the assessment of intertidal macroalgal composition and abundance near to and distant from salmon farms in the Huon and D’Entrecasteaux Channel region eleven years after the initial assessment. 2. To evaluate the potential of using Unmanned Aerial Vehicles (drones) to monitor macroalgal distribution. Read moreRead less
Functional Analyses of Bacteria Involved in Enhanced Biological Phosphorus Removal from Wastewater. The abundant growth of blue-green algae in global waterways is substantially caused by phosphorus (P) release from wastewater treatment plants. This environmental drama can be mitigated against by P-accumulating bacteria partitioning the P inside their cells. The P-removal process often fails, but since the metabolism of P-accumulating bacteria is unknown, remedial actions are based on conjecture ....Functional Analyses of Bacteria Involved in Enhanced Biological Phosphorus Removal from Wastewater. The abundant growth of blue-green algae in global waterways is substantially caused by phosphorus (P) release from wastewater treatment plants. This environmental drama can be mitigated against by P-accumulating bacteria partitioning the P inside their cells. The P-removal process often fails, but since the metabolism of P-accumulating bacteria is unknown, remedial actions are based on conjecture. This fundamental, knowledge-generating project will address this shortfall and will develop methods to evaluate the activity of P-accumulating bacteria, contributing substantial understanding of their metabolism. The final goal is to promote stable, reproducible P-removal from wastewater.Read moreRead less

Contamination by poorly treated and untreated sewage can severely degrade the quality of Australian surface waters. However, the behaviour of organic chemicals during conventional sewage treatment processes remains poorly understood. Furthermore, raw sewage pollution is generally not distinguishable from properly discharged treated sewage effluent by current analytical methods. The proposed research will provide a chemical marker for characterising treatment processes and identifying untreated sewage pollution. This will help to identify sources of such pollution so that they may be corrected. A principal outcome of the research will be the improved ability to protect Australia's valuable surface waters from sewage pollution.Read moreRead less
