Ozone ( O3 ) is a molecule composed of three oxygen atoms. It forms when oxygen molecules become sufficiently excited to split into two different energy levels of atomic oxygen, and collisions between these atoms are the cause of ozone formation. It is an allotrope of oxygen, meaning it results from the rearrangement of oxygen atoms when molecules are released. Therefore, it is the most reactive form of oxygen.
In this article we are going to tell you everything you need to know about ozone, its characteristics and importance for life.
What is ozone
Ozone is a gaseous compound with a blue hue. In its liquid state, it is indigo blue at temperatures below -115°C. Essentially, ozone is a powerful oxidizer, which is why it disinfects, purifies, and eliminates pathogenic microorganisms such as viruses, bacteria, fungi, mold, spores, etc.
Ozone can eliminate bad odors by directly attacking the source of the smell (the odorous substance) and does not add any other scent, such as air fresheners, to try to mask it. Unlike other disinfectants, ozone is an unstable gas that will quickly decompose into oxygen under the action of light, heat, electrostatic shocks, etc. , so it leaves no chemical residue.
Ozonation is any treatment that uses ozone. Its main applications are environmental disinfection and deodorization, as well as water treatment and purification, especially in the context of improving water quality, which is fundamental to the importance of ozone . This process eliminates pathogenic microorganisms and odors, which is essential for maintaining healthy environments.
Ozone can be produced artificially using an ozone generator or ozone generator. These devices introduce oxygen into the air and generate a voltage discharge across the electrodes (called the "corona effect"). This discharge separates the two atoms that make up the oxygen atoms , which then combine three or three of these atoms to form a new molecule called ozone (O3).
Therefore, ozone represents the most active form of oxygen, made up of three oxygen atoms, which can combat pathogenic and / or harmful organic compounds (the main component of environmental pollution).
Uses
This may be ozone's most important characteristic, and it has many other applications. Microorganisms are any form of life that the human eye cannot see and requires a microscope to observe. Microorganisms called pathogens are those that can cause infectious diseases. They commonly survive on all types of surfaces and in all types of fluids, or float in the air, often accompanied by small dust particles, especially in enclosed spaces where the air is renewed very slowly.
Due to its oxidizing properties, ozone is considered one of the fastest-acting and most effective microbicides known, capable of targeting a wide range of microorganisms, including bacteria, viruses, fungi, and spores. All of these microorganisms are responsible for human health problems and unpleasant odors, a fact that has been the subject of various studies on their effectiveness.
Ozone inactivates these microorganisms by reacting with intracellular enzymes, nucleic acid substances, and their cell envelopes, spores, and viral capsids. In this way, due to the destruction of genetic material, the microorganisms cannot mutate and develop resistance to this treatment. Ozone's role is to oxidize the particles of the cell membrane to ensure that they do not reappear.
Ozone treatment is odorless, so it not only disinfects and neutralizes all types of odors, but also leaves no lingering smells after use. It's important to note that ozone produces no residue; as an unstable particle, it tends to revert to its original form, oxygen (O2). Therefore, it is environmentally friendly, safe for products, and ensures the well-being of people. Furthermore, ozone treatment is associated with advanced techniques for reducing environmental pollution and creating healthy spaces.
Another function of ozone is its ability to eliminate any type of unpleasant odor without leaving any residue. This type of treatment is very useful in enclosed spaces where the air cannot be constantly refreshed . In these spaces, if a large number of people enter, unpleasant odors (tobacco, food, dampness, sweat, etc.) will develop due to the effects of suspended molecules and various microorganisms.
There are two ways ozone attacks odors: first, it oxidizes organic matter, attacking it directly, and second, it attacks the microorganisms that feed on it. Ozone can eliminate a variety of odors. It all depends on the nature of the odor-causing substance. Based on this property, you can determine its vulnerability to ozone and the necessary ozone dose for elimination.
Ozone layer
Ozone is an important protector of life on Earth's surface. This is due to its function as a protective filter against the Sun's ultraviolet radiation. Ozone primarily absorbs the Sun's rays with wavelengths between 280 and 320 nm.
When the sun's ultraviolet radiation strikes ozone, the molecule breaks down into atomic oxygen and ordinary oxygen. When ordinary and atomic oxygen meet again in the stratosphere, they recombine to form an ozone molecule. These reactions are constant in the stratosphere, where ozone and oxygen coexist, and ozone plays a vital role in environmental health.
Ozone is produced primarily when oxygen molecules receive a large amount of energy. When this happens, these molecules become atomic oxygen radicals. This gas is extremely unstable, so when it encounters another ordinary oxygen molecule, it will combine to form ozone. This reaction occurs approximately every two seconds.
In this case, the energy source of ordinary oxygen is ultraviolet radiation from the sun. Ultraviolet radiation is the cause of the decomposition of molecular oxygen into atomic oxygen. When atoms and molecules of molecular oxygen meet and form ozone, it is destroyed by the ultraviolet radiation itself.
The ozone layer is constantly undergoing a process of creation and destruction of ozone molecules , molecular oxygen, and atomic oxygen. This dynamic equilibrium involves the continuous formation and destruction of ozone. Ozone acts as a filter, preventing harmful radiation from reaching the Earth's surface.
