Alkaline PH level water ionizers work by passing your tap water through the following stages:
Stage 1: Filtration
In the first stage, water from your household supply line enters the water ionizers' filtration system. It goes without saying that this water contains both positive and negatively charged molecules as well as minerals.
This water, before undergoing ionization, is filtered to remove common pollutants such as chlorine, odor, particular matter, and organic matter, similarly to the process of reverse osmosis. Once these pollutants are removed, water is sent to the next stage.
Stage 2: Electrolysis
Alkaline PH level water ionizers contain two platinum-coated titanium plates known as electrodes. One of these plates is positively charged (anode) whereas the other carries a negative charge (cathode).
These plates attract the positively charged water minerals at cathode, with the negatively charged water minerals going towards the anode.
As that happens, the water on the cathode, which ends up losing electrons, is termed as alkaline water. Whereas that on the anode which gains those electrons become acidic.
Stage 3: Supply
In this stage, the filter delivers the reduced ionized water into your faucet and the oxidized water into your sink. You can use ionized water for drinking. The acidic PH level water, though, should only be reserved for cleaning purposes.
