Internal wave energetics, mixing and transport in lakes. The aim of this project is to increase our understanding of the physical processes controlling water quality in lakes. Water supplies world-wide are under increasing pressure from development, usually resulting in decreasing water quality. The biology and chemistry in lakes is controlled primarily by physical processes, and so understanding these processes is crucial to managing water quality in lakes and reservoirs.

The biology and chemistry in lakes is controlled primarily by physical processes, and so understanding these processes is crucial to managing water quality in lakes and reservoirs. The outcomes of this project will be improved tools for the management of these water resources, as all the research findings will be incorporated into already existing numerical models for lake management.Read moreRead less

Application of the MIEXR DOC process to membrane hybrid systems for water reuse. Fresh water is increasingly scarce in Australia and wastewater reuse is being advocated as a strategy for both meeting our needs and protecting the environment. This research will test the magnetic ion exchange (MIEX) process as a pretreatment for a membrane-flocculation hybrid system (MFHS). MIEX will remove small and medium molecular weight organics and minimize membrane fouling. Large molecular weight organics, s ....Application of the MIEXR DOC process to membrane hybrid systems for water reuse. Fresh water is increasingly scarce in Australia and wastewater reuse is being advocated as a strategy for both meeting our needs and protecting the environment. This research will test the magnetic ion exchange (MIEX) process as a pretreatment for a membrane-flocculation hybrid system (MFHS). MIEX will remove small and medium molecular weight organics and minimize membrane fouling. Large molecular weight organics, suspended solids and micro-organisms will be removed by MFHS. This research will pioneer a novel hybrid system for treatment and reuse of domestic wastewater for non-drinking purposes and provide high quality research training of a doctoral student.Read moreRead less

Interdisciplinary greenhouse gas assessment - nitrous oxide emissions from marine wastewater disposal. Data generated during this research will resolve ongoing uncertainties surrounding a blind spot in national greenhouse gas (GHG) abatement policy and methodology.

Data generated during this research will resolve ongoing uncertainties surrounding a blind spot in national greenhouse gas (GHG) abatement policy and methodology. Current national and international GHG emission estimates are unable to account for N2O emissions resulting from the downstream disposal phase of the wastewater management cycle, and as a result, actual GHG emissions may be far greater than currently estimated. This research will provide primary data on the magnitude of downstream N2O emissions coming from the near-shore marine disposal of primary-level municipal wastewater in Australia. Results from this research will help quantify the carbon footprint associated with marine disposal of poorly treated effluents worldwide.Read moreRead less
