Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its ....Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its beneficial use to enhance nitrogen removal, which is otherwise typically unsatisfactory due to the lack of organic carbon to support denitrification. The project will provide strong support to the Australian water industry in their endeavour to achieve energy- and carbon-neutral wastewater services.Read moreRead less
Production of Biodegradable Polyhydroxyalkanoate Polymers using Advanced Biological Wastewater Treatment Process Technology. The aim of this project is to develop a sustainable process for producing biodegradable polyhydroxyalkanoate (PHAs)polymers from an innovative aerobic-anaerobic biological wastewater treatment process, ?treating? high strength food industry effluent. These biopolymers offer enormous potential for use as renewable and biodegradable thermoplastics.

The aim of this project is to develop a sustainable process for producing biodegradable polyhydroxyalkanoate (PHAs)polymers from an innovative aerobic-anaerobic biological wastewater treatment process, ?treating? high strength food industry effluent. These biopolymers offer enormous potential for use as renewable and biodegradable thermoplastics.
It is proposed to investigate two process configurations, namely the sequencing batch reactor and a continuous two step anaerobic-aerobic reaction system. These will be studied at bench-scale. The outcomes include:
1. Determination of the optimum microbial conditions and key growth
parameters for the production of PHA.
2. Optimisation of the process configuration, operating strategies
and operating conditions to maximise the
production of PHA.
3. Assessment of the influence of the feed composition (e.g. VFA)
on the PHA composition (PHB/PHV).
