Abstract: Water is a scarce resource, and new collection and production facilities are predicted as necessary in the coming years. Sea water desalination shall be a key technology for the production of fresh water in many areas of the world, and great efforts are now in progress to increase the reliability of the desalination processes and to reduce the relevant investment and operation costs. In this effort, new conceptual desalination process and schemes have been implemented with remarkable innovative content by desalination engineers worldwide. This paper is focused on a quite innovative and inexpensive new process. This process was originally tested by the former SOWIT in Italy and is now redesigned on independent parameters by the National Institute of Ocean Technology (NIOT) in India, for the same specific installations on islands of the Indian Ocean.

Keywords: sustainable desalination; low temperature thermal desalination; LTTD; flash; solar energy; sustainability; seawater desalination; India; Indian Ocean islands.
