Water Electrolysis

Diaphragm electrolysis takes place in a water ionizer.


A direct current flows from the negative pole to the positive pole, whereby the electrons flow over the ions dissolved in water.
Water in the cathode chamber becomes alkaline and electron rich (H2 saturated) because of different electrochemical processes that occur. In the opposite anode chamber it becomes acidic and electron poor (O2 saturated), which is noted in the change of the Oxidation Reduction Potential (ORP).
The negative ORP supplies the alkaline activated water with antioxidant properties in the cathode chamber.
The reason for this is dissolved hydrogen gas. The pH value of pH neutral water can be raised with electrolysis up to ca. pH 12.9. For example, in Germany a maximum value of pH 9.5 is approved. Therefore each ionizer can be set so that the maximum drinking pH value is not exceeded.

Even if the 9.5 pH limit is inadvertently exceeded, alkaline water is not a harmful substance, nor is it caustic like a chemical lye with the same pH value.

Even extremely acidic activated water with a pH value of 2.5 does not attack the body, for compared to stomach acid with a pH value of 2.5 it is only weakly buffered. 6)

About Karl Heinz Asenbaum

The Munich-based journalist has been working on the topic of "alkaline activated water" since 2004. For 12 years he worked closely with the alternative physician Dr. Walter Irlacher, with whom he wrote two successful books: "Service Manual for Humans” (Service Handbuch Mensch) (2006) and "Drink Yourself Alkaline” (Trink Dich basisch) (2008,2011). Since 2014 he has been contributing his knowledge and experience to Aquacentrum and giving lectures worldwide. “Electro-activated Water", the world's most comprehensive book on the subject, was published in 2016. View all faqs by Karl Heinz Asenbaum
