Membrane-based power generation from seawater treatment and desalination processes

This chapter gives an overview of the different technologies available for energy recovery and power generation from membrane-based desalination processes. In addition to introducing current desalination technologies, the basic principle of salinity gradient energy and technologies such as pressure-retarded osmosis and reverse electrodialysis are presented. This chapter also summarizes state-of-the-art devices for energy recovery used in reverse osmosis desalination as well as promising, novel alternative techniques for power production with membranes.
