- Abstract:
- The energy recovery devices (ERD) can greatly reduce the energy consumption and cost of freshwater production of reverse osmosis seawater desalination, which is the standard configuration of reverse osmosis seawater desalination system. This paper described the development history and characteristics of hydraulic turbine and work-exchange ERD, summarized the present research of the ERD in China, compared the performance of the typical ERD, and listed the application projects of ERD for large-scale reverse osmosis system in China after 2005. As the energy recovery efficiency is higher than 90%, the work-exchange ERD are emerging as a research and application hot spot in seawater desalination industry. In addition, Chinese-made work-exchange ERD are developed and have been successfully applied in domestic large-scale reverse osmosis seawater desalination project.
