Desalination of geothermal waters using a hybrid UF-RO process. Part I: Boron removal in pilot-scale tests

► Research areas include waters with boron from 2.5 to 96.7 mg/L. ► The study involved reverse osmosis system with low-pressure BWRO membranes. ► Boron were rejected effectively from geothermal water with B up to ca. 10 mg/L. ► Efficient desalination was obtained with TDS of up to 7 g/L.
