A water ionizer works on the simple principle of electrolysis. Any type of water ionizer has two electrodes put into a container having two chambers separated by a semi-permeable membrane. The two electrodes - positive and negative, are put into two separate chambers and the current is passed through them. Ionization process takes place on passing of the current through the electrodes. The dissolved minerals get attracted either to the positive or negative electrode,therefore one of the chambers will have acidic water while the other will have alkaline water. The alkaline water is for drinking purpose, whereas the acidic water is for disinfecting or sterilizing purposes.
The key factor for a quality water ionizer is the material of the electrodes. Most good ionizers on the market use electrodes made of platinum plated or mixed metal oxide coating on grade 1 titanium. Titanium will not dissolve in your ionized water as the cheaper metals like stainless steel does. The 2G ionizer uses grade 1 titanium electrodes to be plated with a good electrical conductor with longevity built to last 10 years that will also not dissolve during electrolysis. Stainless steel was used for Water Ionizer electrodes in the late 1980's and was found not be a suitable material because they did not last more than a a few years. The industry began using titanium platinum-coated or titanium base coated with mixed metal oxide in the early 1990's because it will last indefinitely.
A water ionizer electrodes are one of the most important components and it falls into two basic categories – flat or mesh, flat plates are pretty straightforward and smooth, no texture. Just a titanium plate with the platinum coating. Mesh plates come in a variety of designs. These plates start with a solid piece of high-grade titanium which is then textured in a number of different ways. Once the plate has been “textured” it is double-coated with platinum. Mesh electrodes are used based on the layers of electrical conductivity which indicate that textured metal surfaces are better conductors of electricity than flat metal surfaces when the coated squaremeter are same. This is why most newer water ionizer technology now uses electrodes with some sort of mesh design. There coating falls into mixed metal oxide coating and platinum, generally, the mixed metal oxide coating electrode is of good conductivity and less expensive compare with platinised titanium electrode, while platinised titanium anodes are of better conductivity.
