Fraunhofer Water Systems Alliance (SysWasser)The process of gravitation-supported vacuum evaporation for desalinating seawater uses heat efficiently at low temperatures and is a simple and robust alternative to conventional methods.
The vacuum is created and maintained by gravitation with the advantage that vacuum or jet pumps are not required.
The energy requirements are low so that solar collectors are sufficient for providing the necessary thermal energy and photovoltaic modules for running the electrical components.
