Abstract
The world is facing a severe crisis of fresh water shortage. Seawater desalination technology is the ideal answer to this crisis. However, the conventional technologies consume too much energy, which greatly restrict their popularization. A method for saltwater desalination is proposed based on high-voltage static electric field eliminating the dissolved ions in saltwater. The desalination function is realized by static high-voltage electric field exerting electric force on the ions in the salt solution to strongly separate the ions of the contrary sign. Three factors were simulated to reveal their effects on the ion distribution or the separation efficiency, including salt concentration, electric field intensity and width of water pipeline. Results shows that the above three factors greatly affect the ion distribution characteristics in the water pipeline. This method is helpful in energy saving for seawater desalination.
