How does a Water Ionizer Work

Ordinary tap water goes into a water ionizer and out comes antioxidant alkaline water with amazing health benefits. But how? Do these machines add anything to your water? No. A water ionizer adds nothing to your water. What it does is convert the bicarbonate minerals in your water into hydrate minerals, which are more alkaline, and easier for your body to absorb. The technical name for the process used in this conversion is electrodialysis.
What water ionizers don’t do: Microclustering and restructuring
There are a lot of misconceptions and flat-out falsehoods out there about how water ionizers work, so let’s clear some those up: Water ionizers don’t split water molecules, you need an immense amount of electrical power to do that. Nor do they “restructure” or “microcluster” water molecules. There is no such thing as “restructured” or “microclustered” water. Both of those things are sales fiction that were made up based on discredited theories. You may have heard Kangen Water salespeople claim that their machines do both, but that’s false. In fact, water ionizers have no effect on water molecules whatsoever. What water ionizers work on is the minerals in water, not the water molecules themselves.
The chemistry of water ionizers
When water goes into a water ionizer, two streams of water come out: One is alkaline, which is for drinking, and the other is acidic, which I use as a hair rinse, for watering plants, and even for treating skin conditions on horses! Here’s why a water ionizer needs those two water outlets:
Tap water has calcium and magnesium bicarbonates in it. Bicarbonate is dissolved CO2. So tap water is basically a solution of calcium and magnesium bicarbonates. Water ionizers use electromagnetically-charged plates that are separated by a special membrane to separate the calcium and magnesium in your water from the bicarbonates. It works because calcium and magnesium are positively charged, and bicarbonate has a negative charge. So the ionizer pulls them apart and discharges them in separate streams of water: One is alkaline, the other is acidic.
The alkaline water contains the calcium and magnesium. These minerals undergo a separate reaction after they are separated from the bicarbonates called hydrolysis: The minerals combine pull a hydroxyl ion from a water molecule. That is the process that forms the mineral hydrates - calcium hydroxide and magnesium hydroxide - that give alkaline water it’s healthy qualities.
The bicarbonate also undergoes hydrolysis, it forms a solution of carbonic acid. It’s the carbonic acid that make the acidic water from a water ionizer beneficial to hair, skin, and plants.
More than just healthy minerals, antioxidant potential
The hydrate minerals in alkaline water are part of the reason it’s good for your health. The other reason is that alkaline water made by a water ionizer has antioxidant potential. Alkaline water’s ability to act as an antioxidant is measured in millivolts (mV). It’s called Oxidation Reduction Potential (ORP) it’s a measure of how many free electrons are available in the water to counteract harmful Reactive Oxygen Species (ROS) and free radicals. During electrodialysis, that electron charge builds up in the alkaline water because it is generated at the ionizers’ negatively charged plate. That causes the alkaline water ends up with a measurable negative electron potential, and the higher it is, the better it is for you. Powerful ionizers can reach an ORP higher than -800 Mv.
How to choose the best water ionizer for health benefits
For health, you want two things from a water ionizer: An abundance of hydrate minerals and high antioxidant potential. When shopping for a water ionizer, remember that more is better. Water ionizers with more power and more plates perform better than lesser machines, it’s that simple.
