Major Steps of the CapDI Process:

1. Purification

As saline water flows into the CapDI module, the oppositely charged electrodes attract the ions and pull them through the selective membranes where the ions collect on the electrodes. Clean, desalinated water flows out of the system.

2. Regeneration

Once the surfaces of the electrodes become saturated with ions, they are regenerated by reversing the electrical charge of the electrodes. Since like charges repel, the ions are pushed out of the electrodes and become trapped between the membranes.

3. Flushing

The concentrated brine between the two membranes is flushed from the system. The charge of the electrodes is returned to normal and the system is again ready to desalinate.
