This project aims to develop management approaches to enable the use of anaerobic co-digestion — the conversion of organic wastes and wastewater sludge to biogas for electricity production. Anaerobic co-digestion has the potential to bring significant economic savings to water stakeholders and environmental benefits to communities. However, full-scale deployment faces fundamental challenges in terms of managing impacts on downstream processes (e.g. odour, dewaterability, biogas quality, and nutrient build-up). The analytical framework and analytics tool to be developed in this project by an interdisciplinary team with expertise in process engineering, biochemistry, analytical chemistry and analytics, is expected to enable water stakeholders to cost-effectively manage these impacts and thus realise the benefits of co-digestion.Read moreRead less

This project aims to develop an innovative technology and the underpinning science to achieve stable and efficient mitigation of emerging microplastics induced inhibition that is becoming a key barrier hindering waste-to-energy conversion in anaerobic digestion. Anaerobic digestion is a low-cost technology widely used to divert sewage sludge to renewable energy production. However, the increasing levels of microplastics captured in sludge leads to low methane yield and process failure due to their small size and specific characteristics. The outcome of the project will remove the emerging barrier to enhance energy recovery that can be applied in existing anaerobic digestion infrastructure for addressing Australia’s increasing energy demand.Read moreRead less

This project aims to develop an innovative technology and the underpinning science to gain renewable liquid bioenergy from sewage sludge and realise sludge reduction on an economical and safe platform, by directly transforming sewage sludge into high-value medium chain fatty acids, allowing for easy collection, storage and transportation. Wastewater treatment is generating an increasing quantity of carbon-rich sewage sludge, which typically represents a substantial, but largely untapped, renewable resource. The intended outcome of the project will transform sewage sludge from a troublesome waste stream to a valuable resource that can be applied in existing sludge treatment infrastructure for addressing Australia’s increasing energy demand.Read moreRead less
Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based ....Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based waste (including food, garden, paper, and wood) and fossil-fuel derived materials (plastics). Using an innovative and environmentally-sustainable catalytic process, the outcomes of this project are aimed alleviating Australia’s dependence on diesel fuel imports and better waste management solutions in Australia.Read moreRead less
Defining Fundamental Principles for the Design and Operation of Membrane Systems from Time-Varying Performance Analysis.

To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are likely to be derived from the application of advanced engineering principles to this complex system. This project will integrate advanced CFD modelling and control principles for the design and operation of membrane systems in order to develop fundamental understanding that should lead to significant process improvements.Read moreRead less

Development of Vibratory Submerged Membrane Systems for Water and Wastewater Treatment. While there has been a dramatic increase in the use of submerged membrane systems in recent years, fouling of these membranes remains a major limitation to their more widespread use with the commonly used antifouling approach of bubbling with air exhibiting serious limitations.

While there has been a dramatic increase in the use of submerged membrane systems in recent years, fouling of these membranes remains a major limitation to their more widespread use with the commonly used antifouling approach of bubbling with air exhibiting serious limitations. Low frequency vibration of submerged membranes appears to offer substantial benefits with regard to increased flexibility of operation (such as the ability for rapid turn up/turn down and the ability to minimise fouling in anaerobic systems)and is likely to further extend the use of membranes in water and wastewater treatment.Read moreRead less
