Carbon dioxide in water nanoemulsions for carbon sequestration. The project will address a key objection to geological carbon dioxide (CO2) sequestration by removing the risk of long-term leakage to drinking water aquifers or to atmosphere. By injecting a nano-emulsion of CO2-in-water, the project seeks to show complete reaction to permanently stable solid carbonate occurs within weeks, eliminating the need for secure caprock or extended seal integrity monitoring.

By injecting a nano-emulsion of CO2-in-water, the project seeks to show complete reaction to permanently stable solid carbonate occurs within weeks, eliminating the need for secure caprock or extended seal integrity monitoring. New knowledge will be generated using innovative approaches to create and stabilise CO2-in-water nano-emulsions and demonstrate the fast conversion of CO2 into stable minerals. The benefits are significant in opening potential sequestration targets to include areas without secure caps, reduced cost and elimination of long-term leakage riskRead 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.

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

This project aims to deliver a ready-to-deploy and scalable modular technology that is capable of removing poly- and per-fluoroalkyl substances (PFAS) from a variety of water sources, including groundwater and surface waters, to make them virtually PFAS-free and therefore safe for human consumption. The concept draws on recent advances in water treatment and electrochemistry that is based on ion exchange, nanofiltration and advanced oxidation. A risk-based framework will be developed to deliver fit-for-purpose solutions at minimal cost for stakeholders and taxpayers. This project is expected to benefit the residents who live in the vicinity of contaminated waterways or consume water from polluted sources.Read moreRead less
Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams ....Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams will enhance the health of receiving water bodies and reduce the risk of increased build up of contaminants if wastes are recycled into wastewater treatment plants. New ways to treat such contaminants will be explored, the efficiency and cost evaluated in the broader water cycle and sustainability framework.Read moreRead less

Optimisation of nutrient removal, membrane fouling and sludge dewatering in hybrid coagulation/submerged membrane bioreactor treatment of wastewaters. Submerged membrane bioreactor technology for the treatment of wastewaters is now a competitive technology with small footprint and generally high quality of treated effluent.

Submerged membrane bioreactor technology for the treatment of wastewaters is now a competitive technology with small footprint and generally high quality of treated effluent. Despite this, challenges remain in ensuring low effluent nutrient concentrations, minimal membrane fouling and acceptable excess sludge dewaterability. Addition of iron or aluminium-based coagulant chemicals can assist but many uncertainties with regard to choice of chemical, optimal dosing arrangements and membrane bioreactor operating conditions remain. Experimental and computational studies targeted at improving understanding and optimising performance will be undertaken through collaborative studies by the UNSW and Tsinghua University (Beijing) research team.Read moreRead less
