This project aims to develop a self contained skid-based transportable process for onsite destruction of per- and poly-fluroalkyl substances (PFAS) toxins at contaminated sites. The new technologies developed will span a range of application areas, although remediation of sites contaminated with PFAS by ongoing or legacy use of fire-fighting foams is a key target for this project. The process is expected to enable remediation of these sites by completely converting all toxins into safe products such as carbon dioxide and harmless salts. This project will deliver significant benefits, as the process is easily scalable and is intended to form the basis of a new or expanded remediation industry in Australia, resulting in manufacturing growth, job opportunities and significant impacts in terms of environmental safety and quality.Read moreRead less

Thermal decomposition of PFAS. This project aims to investigate the thermal decomposition of per- and poly-fluroalkyl substances (PFAS). The project will focus on the catalytic destruction of PFAS reactions at elevated temperatures, which is expected to transform PFAS in a controlled and predictable way into benign products. By understanding the fate of these compounds during thermal decomposition, the project will allow the development of a new technology aimed at treating materials which have ....Thermal decomposition of PFAS. This project aims to investigate the thermal decomposition of per- and poly-fluroalkyl substances (PFAS). The project will focus on the catalytic destruction of PFAS reactions at elevated temperatures, which is expected to transform PFAS in a controlled and predictable way into benign products. By understanding the fate of these compounds during thermal decomposition, the project will allow the development of a new technology aimed at treating materials which have been contaminated with or have been used as absorbants for PFAS. The project will provide the technical underpinning of a new technology developed to treat fluorochemical-contaminated material and, in doing so, reduce the environmental impact of these contaminants.Read moreRead less
University of Queensland/Arizona State University partnership to design industrially suitable zeolite membranes for desalination. For desalination, the highest costs are organic-based membrane replacement (lasting ~1 year) and energy requirement. Functionalised zeolitic membranes are low-cost, high performing, chemically tolerant and thermally stable. New zeolite membranes in principle could perform the separation outlasting their organic counterparts, while at the same time offering major energ ....University of Queensland/Arizona State University partnership to design industrially suitable zeolite membranes for desalination. For desalination, the highest costs are organic-based membrane replacement (lasting ~1 year) and energy requirement. Functionalised zeolitic membranes are low-cost, high performing, chemically tolerant and thermally stable. New zeolite membranes in principle could perform the separation outlasting their organic counterparts, while at the same time offering major energy reductions from higher fluxes. Current zeolite membrane research for desalination however is lacking. The proposed team offers experience in bringing highly significant lab scale technologies to industrial scales. The outcomes will address mutual priorities between Australia and USA for reliable low cost supply of fresh water.Read moreRead less

This project aims to develop a new class of plasma water treatment reactors by combining the effectiveness of atmospheric air plasma with the effective mixing of bubble columns. Non-thermal plasmas have been demonstrated to degrade PFAS at the laboratory scale, but key questions remain on the mechanisms of action and process scaling. This project brings together expertise on plasma engineering, bubble column reactors, modelling and industrial scaling to address these issues. The expected outcomes of this project are the development and demonstration of a modular, re-deployable plasma bubble column reactor for the one step destruction of PFAS. The benefits of this project are a new low cost method to remediate PFAS contamination.Read moreRead less

Desalination is being established in response to climate change and growing demands on existing supplies. Fresh water from infinitely abundant ocean sources using little energy input will benefit communities by providing affordably a vital resource with minimal greenhouse gas emissions. Fresh water from current desalination costs $2 per kl, being a major expense for a vital resource normally $0.2 per kl. As energy input accounts for half of the desalination cost, the smart ion-selective membrane to be developed in this project has the capability to reduce desalinated water price by 50%. Such an advancement derived from fundamental material properties is a novel contribution to both science and membrane desalinationRead moreRead less

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

Climate change has led to a dramatic reduction in the availability of fresh water in southern Australia. Consequently, seawater desalination and wastewater recycling facilities are growing in number and size throughout the country. This project will directly benefit operation of these facilities by providing insight into the fundamentals of the membranes they utilise. The development of better predictive models of performance will lead to more efficient water production. The project will specifically evaluate the ability of these membranes to retain dangerous contaminants such as endocrine disrupting chemicals and boric acid. Ultimately, the project will lead to lower costs for water production in Australia and better guarantee of supply.Read moreRead less

This project aims to understand the permeation of water through commercially relevant non-porous polymeric membranes. Permeation, solubility and diffusivity will be studied in the vicinity of the glass transition temperature to elucidate the changes in free volume that occur through this transition. Non-linear concentration gradients due to anisotropic swelling will be probed using novel laminated membrane systems. Water clustering will be evaluated by Fourier transform infrared spectroscopy and nuclear magnetic resonance. Results are proposed to be used to build a new phenomenological model of water permeation that can be used directly by engineers in the design of industrial membrane systems.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.

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
