Desalination

o Seawater desalination is very widely practiced around the globe

o More than 13,000 desalination plants are in operation worldwide

o Some plants are more than 50 years oldo The largest (Ashkelon) can produce 370 ML/do Australia’s first major seawater desalination plant in

Perth (2006) produces 145 ML/d, 17% of the city’s needs

Osmosis and Reverse Osmosis

Semi permeable membrane

Osmosis – fresh water naturally moves into more saline water (this is how trees get water)

Pressure

Reverse osmosis – fresh water driven out of salt water
