Not only is ozone a very powerful oxidizing medium, it is also a very powerful non-chemical disinfectant. Ozone has its unique decomposition properties and can be decomposed into non-toxic and environmentally harmless substances, namely oxygen. In Europe, ozone is used in many places: to remove color, taste and odor, to reduce turbidity, to remove organic matter, microflocculation, iron oxides and manganese, and most commonly to sterilize and inactivate viruses. Most of the principle of use comes from the highly oxidizing function of ozone. Ozone can be added in different steps of water treatment depending on the purpose of use. For example, for iron oxide and magnesium, or to obtain agglomerates, it should be added at the beginning. If used to eliminate taste and odor, add it in the middle. In European water treatment, ozone disinfection is not a substitute for chlorine disinfection, but the only choice.

Nine out of ten diseases, including colds and colds, are transmitted by water or airborne bacteria. Like chlorine, ozone kills microorganisms. The disinfection effect of ozone is "direct attack lethal" and oxidizing organisms. The sterilization speed of ozone is 3500 times faster than that of chlorine. The destruction of the virus by ozone is instant, safe and 100%, because ozone is the purifier of nature. The reactive oxidant for chlorine is hydrochloric acid, which is produced when chlorine is dissolved in water. This powerful oxidant has long-term damage to our water resources. Ozone, on the other hand, has no side effects in water treatment, and is called a "nothing added" disinfectant.
