| description | Abstract Seawater desalination is essential for addressing global freshwater scarcity, but it faces challenges like energy consumption and membrane fouling. This study investigates the use of pulsed electric fields (PEF) to enhance the efficiency of the electrodialysis (ED) desalination process. An experimental setup was developed to evaluate the impact of PEF parameters, such as frequency and duty cycle, on the removal of major seawater ions (Na⁺, Mg2⁺, Ca2⁺, K⁺, Cl−, and SO₄2−). And the influence of varying frequencies (0.9 kHz to 2 kHz) on ion removal rates, total dissolved salts (TDS), conductivity, pH, and energy consumption was evaluated. The results demonstrate that higher frequencies (1.85–2 kHz) significantly improve the removal rates of sodium and sulfate ions, achieving up to 90% removal, respectively. TDS concentration was reduced from 50,000 ppm to as low as 1000 ppm, indicating the potential of PEF-enhanced ED for efficient desalination. The analysis reveals an inverse relationship between salt concentration and electrical resistance, highlighting the need to optimize PEF parameters to leverage conductivity changes. Stable pH values and reduced water hardness further confirm the water quality improvements achieved through the PEF-enhanced ED process. The application of (PEF) in the ED process resulted in up to a 30% reduction in energy consumption and an 80% decrease in (TDS) concentration, from the initial 50,000 ppm to as low as 9912.6 ppm under optimized operating conditions, demonstrating the significant efficiency improvements achieved through this approach. This study provides valuable insights into the optimization of pulsed electric field conditions for enhanced seawater desalination, offering a promising approach to address the challenges associated with conventional desalination technologies. |
