How an Alkaline Water Ionizer Works

To ionize means to gain or lose an electron. Direct current flows from (-) pole to (+) pole. Electron current (e-) is opposite to current (I), so the movement of electrons flows from (+) pole to (-) pole.
(See diagram below).

(-) pole gets the electrons H2O + 2e- = 2OH- + H2

(+) pole loses the electrons 2H2O – 4e- = 4H+ + O2
