Özet
According to World Health Organization (WHO) statements, the boron concentration for drinking water should be less than 0.5 mg L-1. This study is aimed to tackle the challenge to obtain a low boron concentration at this level. In recent years, membrane capacitive deionization (MCDI) has started to attract attention as it allows the ions to be removed quickly and easily from the solutions. In this study, initially boron removal rates of ultrafiltration (UF) membrane were tested at different pressures. Then, MCDI system was operated to determine the optimum conditions for boron elimination. The optimum values were 40 ml min(-1) flow rate, 1.1 V applied voltage, 10 min operating time, and pH 13. On the next step, an integrated UF membrane and MCDI system was developed to improve the total boron removal efficiency. The new integrated system exhibited excellent boron rejection performance in the range of 96%-100%. The technical aspects of design concept to reach low boron limits were discussed.
