Desalination of geothermal waters using a hybrid UF-RO process. Part II: Membrane scaling after pilot-scale tests

► Research areas include scaling intensity during geothermal water desalination. ► The water has high concentrations of boron, iron, strontium, and silica. ► High rejection ratios were obtained using low-pressure membranes. ► Prognosis of scaling was calculated. ► The research showed precipitation of: barite, silica, apatite, and copper sulphate.
