Wrap Up: Sequana Stream Webinar Series

As part of the Australia Water Association’s National Water Week, Sequana launched its Sequana Stream Webinar Series with a special discussion that explored the complexity of the desalination process while highlighting the ongoing efforts to reduce negative effects on the environment.

Thank you to our very own Gary Crisp, Chief Engineer, and Ian Filby, National Partner, Energy, Decarbonisation and Major Project Delivery, as well as our special guest Julien Tauvry, Plant Director- Victorian Desalination Project (Watersure), Suez, for sharing insightful data, relevant case studies and upcoming trends within the water industry in Australia.

Some insights and quotes included:

The importance of desalination in addressing Australia’s water future by understanding what desalination is, and the increasing need for water in the country while scoping the competing market and need for these complex plants.
Desalination and its global trends to identify how established technologies work while analysing the rise of emerging processes and the desalination expenditure forecast to 2028.
Highlights on the environmental impact of desalination, focusing on the brine discharges, the desalination plant’s energy consumption, and its carbon footprint.
The solutions to minimise its carbon footprint following the path of Environmental, Social and Governance (ESG). Understanding here where the energy is used in the desalination process, how to facilitate efficiency and activate renewable energy strategies and a circular economy approach (reuse, repurpose, recycle).
Case studies and trends on new technologies or pre-treatment systems in Australia.

‘The challenges that the water sector faces today include the challenge of decarbonisation; and part of the answer, as we have seen globally, is that desalination is vital. It can provide a stable supply of water for drinking, agriculture and industry, and be an enabler of net zero emission industries,’ Ian Filby, National Partner, Energy, Decabonisation and Major Project Delivery.

‘Why is the pretreatment of the reverse osmosis important? Operating it well can extend the life of the membrane. It puts those membranes in the best possible scenario for operation and maximises their effectiveness, reducing the overall energy consumption and the whole life cycle cost. Membranes are replaced less often which creates less residue for landfills. Lastly, resource recovery from brine is also a great opportunity to decrease the carbon footprint of the plant,’ Julien Tauvry, Plant Director- Victorian Desalination Project (Watersure), Suez.

‘A big global issue is that we know how many desal plants are being planned or have been built. Around 1,000,000 membranes go to waste each year. The whole idea for this cycle is to minimise the amount of waste that goes to landfill. You can reuse, repurpose, recycle them, convert them to energy recovery or into infiltration membranes of lesser degree for lesser purpose,’ Gary Crisp, Chief Engineer.
