  • Why should Italy invest in desalination plants?
  • The plants would meet the dramatic need for water in a stable and structured way, bringing Italy in line with the standard followed by countries that have already invested in desalination plants for the production of drinking water, often using Italian technology and know-how.
  • How much is the desalination chemical treatment market worth?
  • The desalination chemical treatment market for scale inhibitors, biocides and cleaners is approximately $600 million, according to Richard Barwell, VP MENA at chemical company BWA Water Additives.
  • Where is thermal desalination used?
  • The desalination process is divided into thermal and membrane applications by type of plant and is mostly used in the Middle East, North Africa, Southern Europe, the US, Southeast Asia and Australia. Over 70% of thermal desalination production is used in drinking water and less than 20% used for industrial applications.
  • What percentage of water is desalinated in Italy?
  • Italy has 4% of desalinated water production compared with its total water consumption (in Spain it is 56%, in Australia 26%). It is done by mostly small plants on small islands (Lipari, Elba and Ischia) – even though the country is a peninsula surrounded by a number of seas.
