Ozone, also known as activated oxygen, is a naturally occurring compound that plays an essential role in protecting our planet from the Sun's UV radiation.1 On the ground, its uses in addressing harmful contaminants in various industries are abundant.
From breathable air to a bacteria-killing compound
Two oxygen atoms, joined together (O2), is the oxygen we breathe every day. But when three atoms join together, the result is ozone or activated oxygen.
Ozone Facts
Ozone is a gas made up of three oxygen atoms (O3). It exists in two main parts of Earth's atmosphere: the stratosphere and near the ground. In the stratosphere, ozone forms a layer that protects life on Earth by absorbing harmful ultraviolet (UV) rays from the Sun. Without this ozone layer, harmful UV radiation would cause serious health problems, such as skin cancer and cataracts.
Near or on Earth’s ground, ozone is used in various industries such as water treatment, air purification, and more because of its ability to reduce bacteria.*

Ozone works primarily through its powerful oxidizing properties. When ozone (O3) comes into contact with contaminants like bacteria or viruses, it oxidizes them. This process involves the ozone molecule breaking apart and transferring an oxygen atom to the contaminants, altering their structure and rendering them harmless.
In the atmosphere, ozone absorbs ultraviolet (UV) radiation, protecting living organisms from its harmful effects. It undergoes a cycle of breaking down and reforming, constantly absorbing and scattering UV rays, which is crucial for shielding life on Earth from radiation-induced damage.

Ozone is safe when used appropriately, but its safety depends on a number of factors including the concentration and location in which it is present.
However, ozone has beneficial uses, particularly in bacterial reduction* in water treatment, air purification, and even in food industries, without leaving harmful residues. When used carefully in controlled environments and at proper concentrations, ozone is a safe and effective tool.
