A research and development project at the University of Queensland (UQ) has been recognized with an international innovation award for its successful approach to combatting odour and corrosion in sewers. Led by Dr Jiuling Li, the project focuses on addressing hydrogen sulphide, also known as 'rotten egg gas,' a common issue in wastewater systems. The team has developed real-time control and chemical dosing technology to tackle the problem efficiently. By utilizing algorithms to predict hydrogen sulphide build-up, monitoring equipment, and precise dosing of control chemicals, the project aims to prolong infrastructure lifespan, reduce odours and toxins, and minimize chemical usage. This innovative solution has already shown promising results in sewer networks on the Gold Coast and in Brisbane's western suburbs. The project has received a Silver Project Innovation Award from the International Water Association. Moving forward, the team plans to test the technology in larger systems and diverse climates. Supported by various organizations, including the Australian Research Council, Urban Utilities, City of Gold Coast, and SA Water, the project underscores the importance of managing odour and corrosion in sewer networks for water management, human health, and environmental protection.
