Recent high-frequency monitoring in water distribution networks (WDNs) shows that pressure perturbations are significantly more dramatic than expected and cause pipe failures with highly disruptive consequences. This project aims to hydraulically calm WDNs to improve their performance, informed by smart sensors. The project will generate insightful knowledge of the hydraulic behaviour of real WDNs. The outcomes will be new strategies to identify, eliminate and suppress harmful pressure perturbations, leading to a reduced burst rate, extended asset life, improved system operation and advanced design principles. The resultant sustainable water assets provide significant economic and environmental benefits to the water industry and society.Read moreRead less

Illuminating Dark Fibres for Smart Water Asset Monitoring. Smart water networks formed by fleets of acoustic sensors to detect developing cracks in water networks have grown rapidly in the past decade but are costly to install and maintain.

Smart water networks formed by fleets of acoustic sensors to detect developing cracks in water networks have grown rapidly in the past decade but are costly to install and maintain. This project aims to overcome this challenge by exploiting unused underground optical fibre cables that are ubiquitous in cities. The result will be low-cost and ready-made distributed sensing systems that protect critical water supplies, supported by intelligent data analytic algorithms that can translate real-time data into valuable information to optimise water asset monitoring. The research outcomes will stimulate a technological revolution in smart water networks, accelerate water digitalisation globally and bring significant economic and social benefits.Read moreRead less
A multi-scale theory for solid-granular transition due to fragmentation. The prediction of rock fragmentation and fragment sizes during its phase transition from solid (rock mass) to granular (ore fragments) is the most crucial problem in a cave mining operation. Current practice relies on empirical tools without fundamentals of fracture, and hence cannot reliably predict the fragmentation process and fragment sizes. This can lead to huge economic loss due to damage to extraction points, hold-up ....A multi-scale theory for solid-granular transition due to fragmentation. The prediction of rock fragmentation and fragment sizes during its phase transition from solid (rock mass) to granular (ore fragments) is the most crucial problem in a cave mining operation. Current practice relies on empirical tools without fundamentals of fracture, and hence cannot reliably predict the fragmentation process and fragment sizes. This can lead to huge economic loss due to damage to extraction points, hold-ups for safety precautions, and mine closures. The project will develop a new theory and models to describe this solid-granular transition, and computational tools for simulations of cave mining operations. The expected benefits and outcomes include safer operations, and better control of production schedule and budgeting.Read moreRead less

Energy dissipation in dynamic fracture of brittle materials is pivotal in mining, civil engineering and defence. The project aims to develop a novel experimentally-validated multiscale theory, with associated models, for characterising and predicting the complete dynamic fracture process of brittle materials. This theory is expected to generate close-to-reality simulations critical for understanding fundamental aspects of energy dissipation in dynamic fracture. The outcomes will enable an optimised control of the fragment size in block cave mining and mineral processing, forecast and prevent fatal rock bursts in underground mines, and minimise catastrophic failures in critical infrastructures challenged by extreme loading, e.g. explosions.Read moreRead less

Achieving Nitrite Shunt For Mainstream Sewage Treatment Using Human Waste. This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process.

This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introducing a novel technology that innovatively harnesses a human waste, the project expects to remove the barrier. Expected outcomes will support the transformation of sewage treatment plants into net-zero energy generators. This should provide economic, environmental and energy benefits for Australia’s water and energy sectors.Read moreRead less
