HydroDeSal - Seawater desalination in the Middle East

More than 70% of Earth is covered with water. And yet, 96% of these water resources are located in oceans and seas with a high salt content. Funded by the German Federal Ministry of Education and Research from 2021 to 2024, researchers at Johannes Gutenberg University Mainz together with partners in Iran and Iraq have developed an approach to enable people in affected regions to desalinate seawater at low cost. Their idea is to use thermally switchable hydrogels that swell in water at a low temperature and retain salt, while they de-swell at a higher temperature and thus release water. Since that process would be driven by the natural temperature difference between day and night, it would be - once installed - free of charge. The HydroDeSal project is currently looking for cooperation partners interested to help translate this innovative research into practice.

"Our goal is to use temperature-sensitive polymer gels to convert seawater from the Persian Gulf into drinking water to supply small settlements in the region - an energy-independent process which is simply driven by the alternation of day and night," explained Sebastian Seiffert, Professor for Physical Chemistry of Polymers at Mainz University.
In our video, Professor Sebastian Seiffert and Dr. Amir Jangizehi explain their idea of a natural desalination process.
