- Electric Field: An electrical current applied across the membranes creates an electric field, forcing ions to migrate across the membranes. Cations move towards the cathode (negative electrode), and anions move towards the anode (positive electrode).
- Concentration and Dilute Streams: The system creates two streams: a concentrated stream containing the removed ions and a diluted stream with reduced ionic concentration. The desired product is the diluted, purified water.
- Stack Configuration: The membranes are arranged in stacks or cells, with spacers creating flow channels between the membranes to ensure even flow distribution and prevent membrane fouling. The number of cells determines the overall system capacity and treatment efficiency.
