Sewer corrosion in urban environments

Recognised as one of the most critical infrastructure assets for urban societies, the maintenance costs for sewer systems run into the billions of dollars a year across the world. A team of UQ researchers have found a way to save water providers hundreds of millions of dollars a year by reducing sewer corrosion.

The team found that a common coagulant which is added in the drinking water treatment – aluminium sulfate – can be a key contributor to the sulfate levels in sewage. This in turn is the primary source of hydrogen sulfide, which creates rapid concrete degradation and is the main cause of global sewer corrosion. This corrosion could be avoided by switching to sulfate-free coagulants at little or no extra cost compared with the potential million dollar savings in sewer maintenance and corrosions costs.

Graphene-based photocatalysts for water purification

Regulations on public drinking water quality are becoming more and more stringent. This requires new water technology to treat freshwater before it is consumed. Traditional water treatment technologies such as membrane filtration and ultraviolet disinfection may no longer be effective in the future. Photocalalysts is an advanced oxidation technology for the removal of containments in water. Utilising the important physical and chemical properties of graphene to design novel photocatalysts, UQ is developing a graphene-based composite photocatalyst, which will find applications in not only purifying water and treating wastewater, but also purifying air.

Coastal Engineering

The Coastal Engineering Research Group conducts a wide range of coastal based research projects under the umbrellas of coastal hydrodynamics, coastal sediment transport and coastal groundwater. The team undertake field, laboratory and numerical investigations into areas such as wave setup, swash processes, rip currents, heavy mineral sorting, coastal morphology, coastal groundwater dynamics and salinity, and river entrance dynamics.

Recently a new field facility has been established at the Spit on Queensland’s Gold Coast in conjunction with Griffith University and the Gold Coast City Council. This innovative field research facility comprises an array of manometer tubes deployed along a single cross-share transect through the surf zone, measuring mean water levels and waves across the surf zone during storm conditions.

Climate change adaptation plan for the provincial capital of Choiseul in the Solomon Islands

Working together with the local Choiseul community, a team of researchers have developed a comprehensive climate change adaptation plan to move the town of Taro, with a population of 800, to the adjacent mainland. Positioned less than two metres above sea level, Taro is under significant risk from tsunamis and ocean storms, as well as the future of climate change and the resulting rise in sea levels.

The relocation of the capital, including schools, hospitals and businesses, will take many decades to complete, and the adaptation plan also aims to increase the community’s resilience to coastal hazards, such as the preparation of a tsunami response plan.

Fertilisers made from waste: supporting a sustainable agricultural industry

The rising cost and shrinking availability of fertiliser has long been of concern to the agricultural industry, not to mention the fact that current global use is unsustainable from a resource and environmental perspective. Researchers were surprised to discover that producing fertiliser from waste is indeed sustainable and can meet global demand.

So far, it has been discovered that approximately 30% of the net Australian fertiliser market can be recovered from Australian wastes, but that globally, up to 100% of phosphorous and potassium and 50% of nitrogen can be recovered from wastes, and reused in fertilisers.
