This review provides a critical assessment of the production process routes of a wide range of value-added products from WAS, their current limitations, and recommendations for future research to help promote more sustainable management of this under-utilised and ever-growing waste stream.
This paper reports on the findings of a 12-month study, undertaken at SA Water and supported by the Australian Water Recycling Centre of Excellence and UniSA, which set out to explore and develop a new approach to energy benchmark and optimise water recycling systems – so-called 'energy-health' benchmarking. The project also made the first steps toward developing a new suite of energy benchmarks for a range of advanced water recycling processes.
Wastewater treatment plays a pivotal role in the protection of public and environmental health in urban precincts and in the recovery of scarce water and energy resources for an increasingly urban and growing global population. Yet wastewater treatment operations are among the most energy-intensive within urban precincts and so there is considerable scope to optimise wastewater treatment plants to improve their energy efficiency and reduce associated carbon emissions.
