What is CapDI © Technology? CapDI is a simple 2-step process of purification and regeneration relying on our patented electrode and ion selective membrane combination.

Ion Exchange Membranes (Coatings)
Feed Hard/ Salty H 2 O
Purified H 2 O
Feed water passes between oppositely charged electrodes which electrostatically remove dissolved ions, leaving pure water flowing out of the cell.
Only negatively charged ions pass Only positively charged ions pass

Low flow feed water flushing combined with flipping the cell polarity allows ‘regeneration’ (cleaning) as stored ions are rejected from the electrode, concentrated in the spacer channel and then flushed from the cell. The cycle is then repeated.
