The efficiency of boron removal from geothermal water was investigated using boron selective ion exchange resins Diaion CRB 02 and Dowex (XUS 43594.00) in a fixed-bed column. The effect of pH and feed flow rate on boron removal from geothermal water was additionally tested using Dowex (XUS 43594.00) resin. Yoon-Nelson and Thomas models were applied to the experimental data to predict the breakthrough curves and model parameters such as rate constants and breakthrough times. The results showed that the models describe the breakthrough curves quite well compared with the all experimental data. Similarly, the model predictions for q(0) obtained both by Yoon-Nelson and Thomas models greatly fit with the experimental results for all conditions and for both boron selective ion exchange resins.
