How Water is Ionized by a Water Ionizer – Life Ionizers
How ionized alkaline (and acid) waters get their pH: The positively charged calcium and magnesium ions to pass through the merane and become concentrated at the negatively charged plates. Calcium and magnesium are alkaline earth metals, they are responsible for giving the alkaline water, made by a water ionizer, its alkaline pH.
