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

Summary
Superhydrophobic thermally rearranged membranes for low-energy separation. This project aims to develop thermally rearranged membranes with superhydrophobicity using novel polymer chemistry and nanofibre morphology. Both water flowrate in membrane distillation and gas flowrate in carbon dioxide stripping from solvents will be increased by minimising the water vapor condensation between the nanofibers; resolving shortcomings in current energy-intensive filtration systems.

Both water flowrate in membrane distillation and gas flowrate in carbon dioxide stripping from solvents will be increased by minimising the water vapor condensation between the nanofibers; resolving shortcomings in current energy-intensive filtration systems. This project will provide significant benefits to Australian communities by advancing cost-effective and energy-efficient potable water production and carbon dioxide separation processes for sustainable development. The advanced materials developed can be manufactured locally and will enhance our national capability in modern manufacturing.Read moreRead less

A mature commodity that can be readily made from renewable resources, ammonia (NH3) offers an environmentally sustainable and low-cost means of transition from fossil fuels to a clean, low-carbon and renewable energy future. The technical challenge is to combust NH3 efficiently with low nitrogen oxides (NOx) emissions. This project will advance the science of NH3 combustion and NOx formation. By applying innovative fixed-bed and fluidised-bed reactor techniques and kinetic modelling, the research will unravel fundamental characteristics and mechanisms of NH3 combustion, NOx formation and in-situ destruction that underpin the development and deployment of practical combustion systems for power generation using NH3 as a carbon-free fuel.Read moreRead less

Summary
Adding value to wastewater treatment - ultrasound enhanced crystallisation. The difficulty of disposing of concentrated liquid wastes is forcing industries to reassess their waste treatment processes and strive for zero liquid discharge. This project will add value to industrial waste by improving extraction of purified water and valuable solutes from such concentrates by combining ultrasound with crystallisation processes.
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 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

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
