Recent Advances in Boron Removal From Geothermal Waters: A Review

ABSTRACT This review compiles and analyses peer‐reviewed studies from a range of scholarly databases, spanning from 2003 to 2025 to provide the most current analyses of technologies for the removal of boron from geothermal waters. The main objective of this study is to describe the dominant technologies and research trends used for boron removal from geothermal waters. The analysis of the literature suggests that the most researched method has been the use of ion exchange resins (37%), followed by hybrid methods (26%) and membrane processes (19%). Although reverse osmosis has been the most researched type of membrane technology, the operational difficulties that occur at high temperatures and saline concentrations have made ceramic membranes of increasing importance. Future research topics include using artificial intelligence for process control and optimization, developing new boron sensors, conducting life cycle analyses and designing low‐cost, high‐efficiency systems with less of an impact on the environment.
