Intracellular manufacturing - high performance biomaterials from methane. The aim of this project is to produce high performance biodegradable polymers directly from methane. The key innovation is employing cutting-edge community genomic and transcriptomic approaches to characterise intracellular production lines in order to tailor polyhydroxybutyrate-co-valerate (PHBV) copolymer microstructures. This is a truly multidisciplinary project bringing together engineers, polymer scientists and molecu ....Intracellular manufacturing - high performance biomaterials from methane. The aim of this project is to produce high performance biodegradable polymers directly from methane. The key innovation is employing cutting-edge community genomic and transcriptomic approaches to characterise intracellular production lines in order to tailor polyhydroxybutyrate-co-valerate (PHBV) copolymer microstructures. This is a truly multidisciplinary project bringing together engineers, polymer scientists and molecular biologists. It is expected that a direct outcome of the project will be the first PHBV copolymer from methane. As such, the project aims to develop technology for the production of tough, flexible and affordable biopolymers and, at the same time, provide an opportunity to add value to methane.Read moreRead less
Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in res ....Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in response to ventilation and dynamic wastewater and atmospheric conditions, enabling model-based sewer ventilation design and operation. The project also aims to deliver novel, field-demonstrated ventilation strategies. The project findings will be incorporated in the Australian ventilation design and operation guidelines.Read moreRead less
An integrated approach to iron salt use in urban water systems. The project aims to develop and demonstrate an integrated and innovative strategy, and the associated science and technologies, to achieve multiple beneficial uses of iron salts in an urban water system. The project intends to use iron chloride to replace the most commonly used alum as a coagulant in water treatment. The same iron is then further used for corrosion and odour control in sewers, phosphorus removal in wastewater treatm ....An integrated approach to iron salt use in urban water systems. The project aims to develop and demonstrate an integrated and innovative strategy, and the associated science and technologies, to achieve multiple beneficial uses of iron salts in an urban water system. The project intends to use iron chloride to replace the most commonly used alum as a coagulant in water treatment. The same iron is then further used for corrosion and odour control in sewers, phosphorus removal in wastewater treatment reactors and hydrogen sulfide removal from biogas in an anaerobic digester. The strategy is expected to substantially reduce the use of chemicals in the entire urban water system, delivering large economic and environmental benefits to urban water utilities.Read moreRead less
In-situ electrochemical generation of caustic and oxygen from sewage for emission control in sewers. This project aims to deliver an innovative technology that controls the emission of notorious compounds from sewer networks using chemicals directly produced from sewage, with electricity being the input. Compared to existing methods, this technology provides a much safer and more environmentally friendly solution, at less than 50 per cent of the cost.
Treatment of secondary sludge using free nitrous acid to enhance performance and economics of a wastewater treatment plant. This project will deliver a new process that utilises a by-product of wastewater treatment to reduce the environmental and financial costs of wastewater treatment. The project will significantly reduce waste materials discharged from wastewater treatment plants and enhance bioenergy recovery from wastewater, in addition to improving effluent quality.
Energy positive targeted resource recovery from sludge. Energy positive targeted resource recovery from sludge. This project aims to develop an innovative, cost-effective and sustainable technology to completely dewater sludge. Sludge management is a notorious and costly issue for water utilities. The poor dewaterability of sludge results in a high moisture content. The only solid residue is inorganic ash, from which valuable resources such as coagulants, phosphate, and metals can be extracted. ....Energy positive targeted resource recovery from sludge.

Methane and nitrous oxide emissions from sewers – understanding, modelling and mitigation. The research and industry partners will collaborate on this project to quantify, understand and mitigate emissions of methane and nitrous oxide in sewer networks. Both methane and nitrous oxide are potent greenhouse gases, and their emissions need to be accounted for and mitigated for the water industry to achieve greenhouse neutral water services.
