Ozone, whose chemical formula is O3, is also known as triatomic oxygen and super oxygen. It is named after its fishy smell. It can be reduced to oxygen at room temperature. Its specific gravity is larger than oxygen, and it is easily soluble in water and easily decomposed, so ozone water is also widely known, as well as ozone water purifiers, ozone water filters, etc. Today we mainly introduce a few frequently asked questions about ozone.
The hydroxyl group produced when ozone is decomposed in water has a strong oxidizing ability, which can quickly remove iron, manganese, odor, bacteria, viruses, etc. in the water, and make the water molecules smaller, making the water taste sweet. The chlorine or trihalomethane in tap water can also be eliminated by ozone.
Ozone is recognized worldwide as the best method for treating raw drinking water. In Europe, there are more than one thousand water plants using ozone for water purification. Since 1906, the world's first ozone water treatment plant was established at Nice, France. By 1975, more than 1,000 ozone deodorizing devices had been installed in sewage treatment plants in the United States. In 1982, bottled water began to use ozone for sterilization. In 1984, all Olympic swimming pools were treated with ozone. In 2000, about 300 water plants in the United States used ozone to do water quality treatment. All swimming pools for the 2008 Beijing Olympics were treated with ozone.
Ozone is recognized as the strongest and most natural powerful oxidant and bactericide in the world. It can instantly kill E. coli, Staphylococcus aureus, Salmonella, Vibrio cholerae and other harmful bacteria in water within two seconds. Its sterilization rate reaches 99.999%.
Ozone can kill more types of microorganisms than chlorine, especially pear-shaped cysts that are resistant to chlorine, only ozone can kill them. The sterilization speed is faster than chlorine, so it can reduce the contact time, the volume of the reaction tank, and increase the processing capacity. After the ozone is oxidized and disinfected, the ozone will automatically reduce to oxygen. However, chlorine will still remain in the water and requires subsequent treatment to eliminate it. Ozone does not produce carcinogenic by-products, while chlorine disinfection will produce carcinogenic disinfection by-products of chloramines and trihalomethanes. Ozone cannot be stored and must be manufactured on-site and used immediately. Therefore, unlike chlorine, there is no risk of transportation leakage and no storage problems.
We can use ozone instead of chlorine for disinfection purposes. When we use chlorine, chlorine and organic matter in the water will react to produce carcinogens and threaten our health. On the contrary, ozone can oxidize and decompose the chlorine in the water and remove molds. At the same time, it can remove terrible odors with its excellent deodorizing effect. Moreover, the bactericidal ability of ozone is 3000 times that of chlorine, and ozone is the biggest nemesis to the cyst of Pyriformis, which is extremely resistant to chlorine.
