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.

The project aims to investigate methods for extracting and converting intermittent energy from variable speed wind generators and supplying to electricity grids. Low cost power conditioning units for integrating small-scale wind generators will be designed, developed and commercialised. It is expected that this project will lead to a systematic design procedure for grid connected inverter technology using a novel current control technique, and extraction of more energy from small scale wind turbines especially at low wind speeds. Successful commercialisation will result in significant reduction in cost resulting wider application of wind turbines, substantial economic benefit to the commercial partners as well as Australian communities in rural areas.Read moreRead less
Optimal management of corrosion and odour problems in sewer systems. Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a yea ....Optimal management of corrosion and odour problems in sewer systems. Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a year in Australia alone. This project is a major joint effort by the Australian water industry and world-leading scientists to generate advanced knowledge and develop effective technologies for optimal odour and corrosion management in sewers, delivering large social, environmental and economic benefits.Read moreRead less
Understanding and mitigating nitrous oxide emission from wastewater treatment plants. Climate change caused by greenhouse gas emissions is one of the most serious challenges that mankind is facing. Substantial reduction in emissions must be achieved, with responsibility to be shared by all industrial sectors. Wastewater systems contribute to greenhouse gas emissions through not only energy consumptions but also direct emissions of fugitive greenhouse gases such as nitrous oxide. This project aim ....Understanding and mitigating nitrous oxide emission from wastewater treatment plants. Climate change caused by greenhouse gas emissions is one of the most serious challenges that mankind is facing. Substantial reduction in emissions must be achieved, with responsibility to be shared by all industrial sectors. Wastewater systems contribute to greenhouse gas emissions through not only energy consumptions but also direct emissions of fugitive greenhouse gases such as nitrous oxide. This project aims to provide knowledge and technology support to the Australian wastewater industry to minimize the emission of nitrous oxide during biological nitrogen removal from wastewater. This is critically important for this industry to achieve greenhouse gas neutral wastewater management.Read moreRead less

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
A HYBRID INTEGRATED SYSTEM FOR MUNICIPAL SOLID WASTE TREATMENT AND POWER GENERATION. The management of solid wastes is a major global environmental issue and the current practice of landfilling is not a sustainable solution. Biogasification of the organic fraction provides not only a means of waste treatment but also generates a source of energy in the form methane but current technologies are expensive due to the long degradation times.

The management of solid wastes is a major global environmental issue and the current practice of landfilling is not a sustainable solution. Biogasification of the organic fraction provides not only a means of waste treatment but also generates a source of energy in the form methane but current technologies are expensive due to the long degradation times. In this project we investigate an innovative waste treatment system that will cut down the time required for processing wastes by a factor of 10 with considerable economic benefit. We will optimise the integration of this treatment system with a hybrid power generation system that utilises other renewable energy sources like solar and wind energy to deliver quality power at minimal cost.Read moreRead less
