Project Background

New South Wales, Australia – Macquarie Generation, one of Australia’s largest electricity generator, was created in 1996 as a state-owned corporation, its shareholder being the New South Wales (NSW) Government.

Approximately 40% of NSW electricity demand is provided through Macquarie Generation’s Bayswater and Liddell Power Stations.

Bayswater Power Station is located 250 km north of Sydney.

 

The Client’s Needs

As part of Bayswater’s water management system, Macquarie Generation wanted to minimise its impact on the environment by restoring the sustainability of the water in nearby Lake Liddell.

This lake originally built for providing the vast amounts of condensate cooling water needed for the station’s operation, has then become a popular recreational lake.

Macquarie Generation wanted to reduce the level of salt discharged into the lake and also upgrade and refurbish the 4 existing water treatment plants which were aging, to improve the reliability and availability of the water treatment plants. Vital cooling water is recycled and treated to ensure that no contaminants reach local waterways.

 

Project & Technology Solutions

Macquarie Generation awarded Veolia Water Technologies with a contract for upgrading Bayswater water treatment plants, both companies sharing the same commitment to responsible environmental management through innovative solutions that guarantee health & safety and protect the environment. We provided a comprehensive and innovative water solution package to Macquarie Generation, including Design & Construction, as well as Operations and Maintenance requirements, in order to meet the long-term water treatment needs of Bayswater Power Plant. The project scope involves 2 years of Design, Build, Construction works and a 5-year Operating and Maintenance period, to meet specific requirements and address concerns in regards to the long-term strategy of the water treatment plants. Veolia Water Technologies who is leading the project, brought together the skills and experience of 4 Veolia companies (Veolia Water Technologies Australia, HPD, Veolia Water Technologies Canada and Veolia Water Australia), each being leaders in their own specialist areas.

 

Process Description

The process includes lime softening, pre-treatment using 8 Actiflo® units for clarification process, filtration, Ion Exchange, Reverse Osmosis, Brine Concentration and Crystallisation. Veolia Water Technologies will:
  • Upgrade the lime softening facility to treat raw water from the Hunter River before it is discharged into Lake Liddell.
  • Upgrade the 4 existing circulating water treatment plants and their associated wastewater reclamation plants, improving their availability and reliability.
  • Using technologies from HPD, world leader in evaporation and crystallisation, modify the existing Brine Concentrators, to improve availability and reliability.
  • Provide a new Brine Concentrator to increase salt removal and treatment capacity.
  • Provide a new Brine Crystalliser, to minimise the water volume to be stored on site. ​
