Desalination

• Seawater desalination is very widely practiced
  around the globe
• More than 13,000 desalination plants are in
  operation worldwide
• Some plants are more than 50 years old
• The largest (Ashkelon) can produce 370 ML/d
• Australias first major seawater desalination
  plant in Perth (2006) produces 145 ML/d, 17 of
  the citys needs
