Water Filtration
There is a wide range of filtration methods currently being used all over the world. Some can be dangerous to handle and very reactive while others can be used in an any day household. Although no filtration method is perfect, combining different forms of filtration can provide near-perfect water. One note to take is that most of the time the more that is filtered, the pricier the method is. Three very effective methods of water filtration are “Ion Exchange”, UV light, and “Ozone”. The most expensive but very effective method of filtering water is through Ion Exchange. It involves replacing ions like Ca2+ and Mg2+ (harmful) with good ions like Na+ or K+. Ca2+ can cause cell injuries and trigger a number of membrane-disruptive processes while Mg2+ in all of its forms greatly increases SRB (Sulfate Reducing Bacteria) growth. SRB causes extreme cases of corrosion and sabotage in water cooling, heating, and filtering systems. Meanwhile Na+ and K+ are ions that “transport cells” and help the “traffic” move along, like police and airplanes in real life. Without Na+ or K+ there would be swelling in the cells and that would be very bad. The downside to Ion Exchange is that it does not remove bacteria and particles effectively. Combined with other methods of filtration, Ion Exchange can become one of the best, if not the best, water filtration methods because it cleans out most forms of harmful ions and bacteria in the water while also boosting the water and providing it with some “vitamins”

Another similar method to Ion Exchange is “Ozone” because of the way the bacteria and harmful chemicals are destroyed. Ozone, by far, is the best method of filtering water. Ozone (O3) is the triatomic form of oxygen. It can destroy more than 99.9992% of everything in water. The Ozone gives its atoms to the oxygen in the water to purify the water. It’s like replacing a...
