What is Ozone?
Ozone is an allotropic (very reactive) variety of oxygen, its triatomic molecule (O3) is generated by the activation of the diatomic molecule (O2) of oxygen. This activation can be caused by the action of an electric shock or by the irradiated energy of ultraviolet rays. It occurs naturally in the upper layers of the atmosphere thanks to the action of ultraviolet rays on atmospheric oxygen, forming the so-called ozonosphere or ozone layer, whose goal is precisely to filter, absorb and reflect ultraviolet radiation from the sun into space. At normal temperatures, ozone is a gas that is in unstable solution in the air, decomposing relatively quickly and converting back to oxygen (O2).
What are its properties?
This is perhaps the most important property of ozone and the one that is relevant for most applications. Due to its oxidising properties, it can be considered one of the fastest and most effective known microbicides. It has a wide spectrum of actions, including the elimination of bacteria, fungi, viruses and nematodes.
This is one of the properties for which ozone is most commonly used, due to how effective it is at treating certain unwanted odours in all types of public places. Not only does it oxidise organic matter (ozonolysis), but it also attacks the microbes that feed on it. Ozone is capable of handling a wide range of different odours.
In large cities, where there are many closed and poorly ventilated places, it is very often noticeable that the air becomes rarified as a result of a lack of oxygen, which we usually identify as stale air.
