Research and Development of Thermal Seawater Desalination Technology

Abstract

There are growing needs for seawater desalination plants all over the world in order to secure stable water resources. Hitachizosen has seawater desalination technologies for three processes (MSF, MED and RO). A significant amount of research and development (R&D) has been carried out in order to constantly improve the technologies and reduce the cost of desalination. This paper describe the features of the processes, overviews of our recent R&D activities and future trends in thermal seawater desalination technologies.
