BrineMine: Extraction of valuable substances and drinking water from geothermal sources in Chile

Membrane distillation for desalination and mineral extraction from geothermal brine wells using geothermal energy. The “BrineMine” project in Chile has been running since March 2019. Since then, a SolarSpring MD plant has been treating geothermal water in the Andes at an altitude of over 4,000 meters above sea level in such a way as to obtain drinking water on…

Project “RE-Salt” – Recycling of industrial process brines

This project deals with the recovery of the salt (NaCl) contained in industrial wastewater streams and its recycling as a raw material into chlorine-alkali electrolysis as well as the further processing of the resulting water. The project comprises the following steps: Development of trace substance analytical methods for highly saline solutions Purification of brines by appropriate adsorptive and electrochemical…

ReSoWas – Adapted control and remote monitoring of decentralized, solar-powered drinking water treatment plants (2014 – 2018). For many decentralized areas, in addition to the scarcity of clean drinking water, a lack of infrastructure and thus a lack of energy sources is characteristic. About 2 billion people have neither electricity nor access to clean drinking water. This is where…
