Ultrasound for control of cyanobacteria. Blue-green algae, also known as cyanobacteria, forms in drinking water supplies in Australia and can cause water-quality problems. Current methods to treat blue-green algae involve the use of Copper Sulphate, which is not an environmentally friendly compound. A potential alternative environmentally friendly water-treatment method involves the use of ultrasound to disrupt the cyanobacteria. The aim of this project is to determine the physical properties of ....Ultrasound for control of cyanobacteria. Blue-green algae, also known as cyanobacteria, forms in drinking water supplies in Australia and can cause water-quality problems. Current methods to treat blue-green algae involve the use of Copper Sulphate, which is not an environmentally friendly compound. A potential alternative environmentally friendly water-treatment method involves the use of ultrasound to disrupt the cyanobacteria. The aim of this project is to determine the physical properties of the cyanobacteria when excited with ultrasound for the purpose of finding an efficient method to treat large volumes of water.

Novel and cost effective mixing technique for anaerobic digesters in municipal wastewater treatment plants. The mixing system and the models that will be developed in this project will be useful in improving the energy efficiency of anaerobic digesters operated in many towns and cities. These improvements will help to reduce greenhouse emissions significantly and also lead to reduced household water bills, as wastewater treatment costs will decrease.
All-solid-state Z-scheme photocatalysts for water treatment. The project aims to develop high-performance Z-scheme photocatalysts by using two-dimensional (2D) semiconductors as building blocks for low-cost, highly-efficient pathogen inactivation and emerging pollutant degradation in stormwater treatment. The project expects to generate new fundamental knowledge in the area of photocatalyst design and Z-scheme photocatalytic system, and advance the application of photocatalytic oxidation in wate ....All-solid-state Z-scheme photocatalysts for water treatment.

The expected outcomes of the project include novel 2D Z-scheme photocatalysts and enhanced capacity in stormwater management.Read moreRead less
Microbial fuel cells for nutrient recovery from source-separated urine. This project aims to reduce the strain on urban wastewater treatment plants by removing and recovering nutrients from water collected in residential and commercial buildings. Urban wastewater treatment plants in Australia are under pressure from increasing population and urbanisation, and there are also ever stricter environmental regulations on discharge of nutrients (mainly nitrogen and phosphorus) into receiving waters. W ....Microbial fuel cells for nutrient recovery from source-separated urine. This project aims to reduce the strain on urban wastewater treatment plants by removing and recovering nutrients from water collected in residential and commercial buildings. Urban wastewater treatment plants in Australia are under pressure from increasing population and urbanisation, and there are also ever stricter environmental regulations on discharge of nutrients (mainly nitrogen and phosphorus) into receiving waters. With many plants operating close to capacity, water utilities may face large expenditure to increase the capacity of existing treatment facilities. This project proposes an alternative solution: decentralised removal and recovery of nutrients from urine separated at the source. It is planned that novel microbial fuel cell technology will be developed to deliver an economical solution, which will additionally generate valuable fertiliser as a by-product.Read moreRead less
Reducing land and infrastructure requirements for water evaporation from biosludge through dry stacking. Melbourne's wastewater treatment plants have limited capacity in their evaporation pans to dry residual solids from wastewater treatment processes. This project will significantly improve the efficiency of new pans by providing an alternative operating method, dry stacking, which has delivered considerable benefits to the mineral industry.
Biosolid flow, separation and activity in anaerobic lagoons. This project aims to develop a fundamental model of the complex, non-steady state flow behaviour in anaerobic lagoons. The project will develop new operating procedures and designs for large municipal, industrial and agricultural anaerobic lagoons. This will improve the efficiency of anaerobic digestion and reduce wastewater treatment costs, as well as increase renewable and sustainable biogas production. The intended outcome is a va ....Biosolid flow, separation and activity in anaerobic lagoons. This project aims to develop a fundamental model of the complex, non-steady state flow behaviour in anaerobic lagoons. The project will develop new operating procedures and designs for large municipal, industrial and agricultural anaerobic lagoons. This will improve the efficiency of anaerobic digestion and reduce wastewater treatment costs, as well as increase renewable and sustainable biogas production. The intended outcome is a validated 3D model that captures the physical and biological complexities of anaerobic lagoons. This will impact the design and operation of partner organisation lagoons, reducing capital and operating costs and improving biogas production.Read moreRead less
Bacteriophages for foam control in wastewater processing. This project will develop new strategies to reduce troublesome foaming at sewerage treatment plants in Australia. It will enable water authorities to prevent foaming events, increase wastewater treatment safety and efficiency, decrease environmental and human health impacts and aid recycling of urban and industrial wastewaters.
Improving the Durability and Performance of Hollow Fibre Membranes with Nanocomposite and Inorganic/organic Hybrid Materials. 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 ....Improving the Durability and Performance of Hollow Fibre Membranes with Nanocomposite and Inorganic/organic Hybrid Materials. 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
Novel concepts for bioelectrochemical generation of renewable fuels and chemicals from wastewater. Global warming and the diminishing fossil fuel resources are posing an ever increasing threat to our societies and economies. This project aims to develop novel and highly innovative bioelectrochemical processes for the production of valuable fuels and chemicals from wastewater, which is a largely untapped renewable resource.
Understanding Droplet Interactions in Solvent Extraction. The aim of this project is to develop an understanding of how organic drops behave in a water phase.
