Abstract

In recent decades, the ever-growing demands for clean water in households and industries have urged researchers to take every possible step to deal with the global water crisis. Seawater desalination has turned out to be the most promising and efficient way to provide clean water. Owing to the advancement of synthetic chemistries and technologies, great success has been achieved in the desalination and utilization of seawater worldwide. China, with the world’s largest population, has pushed the development of desalination and multipurpose utilization of seawater further in respect of materials, technologies and services, etc. This review reports recent progress of desalination technologies accomplished in China, from the viewpoints of facilities and equipment, collaborations, technologies, applications, research abilities, services, and standard systems. Inspired by the Fourteenth Five-year Plan, it also proposes future perspectives of desalination in China.

Highlights

  • Reliable and stable freshwater supply is a prerequisite for the sustainable development of human society

  • A comprehensive review covering the recent project scales, application scenarios, equipment series, standard systems and technical services undergoing in China, especially those initiated by the leading desalination organization of the Institute of Seawater Desalination and Multipurpose Utilization (ISDMU) is still missing

  • Only about 3% of the capacity was provided to seawater desalination projects (1573,760 m3 /d), indicating that RO membranes have been extensively used in many other water treatment projects
