Nowadays, clean water is becoming more scarce. People are getting closer to the adverse effects of climate change, especially the people of Ben Tre province those are heavily affected by seawater intrusion every year. The electrodialysis (ED) model, combined with electrostatic attraction and membrane filtration, has shown the ability to handle nearly 30% of salt concentrations of 5.5−7.9 g/L. The experiment also showed that air bubbles occur when the voltage of the model is increased higher than 26V. The model also promised a stable foundation to develop into a larger−scale model with more treatment stages and low electricity consumption. Moreover, it is possible to reuse the products produced by the ED model with two separate streams: a concentrated stream that can be applied to separate salts and a dilute stream that can be used as domestic water.
