Ozone is a highly unstable gas comprised of 3 Oxygen atoms. When a high voltage electrical charge is applied to oxygen (02), it breaks the bond between the two oxygen atoms and creates singular oxygen atoms. These are highly unstable and bond with existing O2 to create O3. The O3 then takes on the instability of the singular oxygen atom, and finds something to bond with. In water, it seeks out inorganic compounds or living tissue to bond with. The extra oxygen atom attaches to a bacteria, where it quickly breaks down its cell wall. Left with nothing to bond with after destroying its potential dance partner, it then finds another single oxygen atom and recombines again to oxygen (02)
The benefit of this process to humans is that ozone kills pathogens quickly, then quickly becomes regular oxygen again, creating no toxic byproducts. unlike harsh chemicals, ozone is destroyed by the process of destroying pathogens, and the only byproduct is pure oxygen. It is safer than many methods employed to control bacteria or pathogens, and is created on site, rather than having to be shipped in and later disposed of. It is safe to be around so long as you do not breathe it in, since its reactive nature can damage the sensitive tissues of the lungs and nasal passages. It can oxidise organic compounds that create unpleasant smells in the air – imagine a wastewater treatment plant being bombed with ozone during times when no employees are present – and is currently in use in a wide variety of applications and industries all over the world. It is the preffered decontaminant of choice for water bottling facilities, wineries, etc.
