What is Ozone?

Ozone is a highly reactive and unstable form of oxygen. Ozone is made up of three oxygen atoms together, written as O3. It is called activated tri-atomic oxygen. It is a gas and is denser than air. Ozone is the second most powerful sterilant in the world and it destroys bacteria, viruses and odors. Ozone is nature’s way of purifying the air we breathe. It is the distinctive “electric” odour smelled during and after thunderstorms. Ozone derives from the Greek word ozein, which means to smell. If natural ozone ceased to exist, life on this planet would also cease to exist.


The benefit of ozone

Ozone sterilization is considered to be one of the most effective water treatment methods for disinfection.Ozone disinfection is extremely powerful, with strong bactericidal power and broad bacterial spectrum. It can kill bacteria, and viruses. The ozone sterilization mechanism uses oxidation to destroy the structure of the microbial membrane to achieve sterilization. Ozone first acts on the cell membrane, causing damage to the constituent components of the membrane, leading to metabolic disorders. Ozone continues to penetrate through the membrane to destroy lipoproteins and lipopolysaccharides in the membrane, change the permeability of cells, and cause cell lysis and death. The ozone inactivation of viruses is thought to be done by directly destroying their ribonucleic acid RNA or deoxyribonucleic acid DNA substances.

 It has a wide range of applications and is called “universal disinfectant”Mixing ozone in water for disinfection is simple but effective, destroying 99.99% of harmful microorganisms without adding any chemicals to the water. In addition to sterilization, ozone can also deodorize, decolor, and remove iron oxide, phenol, and manganese.

Ozone disinfection technology can be used for drinking water, sea water, sewage treatment, and can also be used for disinfection of environmental objects, etc.

The Ozone Advantages

Ozone sterilization is a bacteriolytic level method, complete sterilization, no residue, broad-spectrum sterilization, can kill bacterial propagules, spores, viruses, fungi, etc., and can destroy botulinum toxin.

  • O3 has a killing effect on mold. Due to its poor stability, O3 will quickly decompose into oxygen or a single oxygen atom by itself, while a single oxygen atom can combine into oxygen molecules by itself without any toxic residues. Therefore, O3 is a pollution-free disinfectant.
  • The disinfected water is non-toxic, tasteless, no side effects, no material contamination, and no water quality changes. After the ozone changes the structure of the microbial protein, the oxygen volatilizes directly and the microbes are killed. No damage to the mineral nutrients in the water. No energy consumption (no heating), simple operation (the gas is diluted directly into the water), and the disinfection is complete and fast.

Environmentally Friendly Method of Filtration

The problem with many types of filtration is the process eliminates pollutants but adds other chemicals.

Ozonation is a Preferred Method of Filtration

Ozone filtration has many benefits outside of water purification. It can remove impurities quickly and leaves no trace


When you are in the water bottling business, you will need to consider using a ozone generator to make sure that you kill all the bacteria that builds up in your storage tank. Every time you open your filling tap, the water goes through the ozone generator all microorganisms that can be harmful to your body.

Why use ozone in water?


How to choose suitable ozone generator for drinking water?

Under the condition of atmospheric pressure mixing, when bottled purified water is disinfected with ozone, 2-3g/h ozone is usually used for 1m3/h water, and the ozone concentration in water should be ≥0.4mg/l.For drinking water,ozone and contact water are needed for 12 min,and the concentration of residual ozone in water is less than or equal to 0.3 m /L.

How does ozone get into the water?

Ozone is a gas and it is only slightly soluble in water. It must be thoroughly mixed in water to help dissolve it. Only in the dissolved state can the chemical reactions with contaminants can take place. The most common way in drinking water is with a venturi injector. The injector’s diameter is smaller in the middle so water travelling into the injector begins to move faster. In the middle of the injector there is a small hole. As water is pumped past the hole, a vacuum is created. The amount of vacuum is dependent on the amount of water flow through the injector – more water equals more vacuum. If a small flexible hose or tube is attached to this small hole, a liquid or gas can be drawn into the injector and mixed into the water.The goal is to make the smallest bubbles possible and to keep the bubbles in contact with the water for as long as possible. The ozone that does get dissolved will kill or oxidise anything in the water.

Frequently Asked Questions

Commercial ozone generators are designed for use in unoccupied spaces. Shortly after treatment the O3 will revert back to O2, leaving no vapors in the air or residue on surfaces. At the same time, ozone is powerful oxidizer and excessive ozone concentrations may cause mucus membrane or respiratory irritation, and can affect people with asthma. Several years ago, a concern developed when consumer air purifiers began to incorporate ozone and were marketed as around the clock units for homes and offices. The possibility of long term exposure for consumers resulted in a notice of caution by government agencies. Therefore, it is always best to use ozone in unoccupied spaces as recommended.

Ozone (O3) is a highly charged form of the oxygen (O2) that we breathe. Outdoors, ozone has been produced for millions of years. At ground level, O3 acts as an oxidizer to keep the air smelling fresh. In the upper atmosphere, ozone acts as a protective layer that partially shields the earth from the sun's UV rays. Life on earth as we know it could not exist without O3. This third oxygen atom is loosely attached, unstable and seeks out pollutants. It will then release and oxidize them on contact.

Ozone is created by lightning during active thunderstorms by splitting O2 molecules in half, and allowing the single molecules to attach to regular oxygen molecules, thus becoming O3. The process is known as corona discharge and often creates a fresh smell in the air after a thunderstorm that can be very distinctive. Ozone is also created by ultraviolet rays from the sun striking the earth and its atmosphere.

The OdorFree generators utilize electricity to create a corona discharge which duplicates the effect of lightning. This technology employs a special transformer that sends a current to the stainless steel screen on the ceramic plate. As a result, the O2 molecule is split, which then combines with other O2 molecules to create the O3 molecule, or ozone.

Ozone is very effective because it will circulate throughout an area and eliminate odors at their source. It actually oxidizes odors as it encounters them, whether they are in the air or on surfaces. These include odors from tobacco smoke, food and beverages, body sweat, animals and pets, garbage, remodeling and many more odor producing substances. It will also follow the same path that the odors took into soft fabrics and oxidize them on contact. Unlike deodorizers, it does not leave a smell or residue in the facility, which some people find objectionable. The treated area becomes free of odors.

Each space that has developed an odor is somewhat unique, so square footage is not always the best way to determine how long the treatment should be. For example, if a hotel room was smoked in for one evening, a 20 or 30 minute treatment should eliminate the odors. However, if the room had been smoked in heavily for a week, it could take several hours of treatment. And to convert a smoking room into a non-smoking room could take as long as 24 hours to eliminate the odors. The ozone output of the OdorFree generators is rated in milligrams per hour. In general, the higher the output the less time it takes to eliminate odors.

Just plug in the unit, select an Ozone Output level on the dial and set the Timer. Close off and vacate the area to be treated, and let the OdorFree do its work. Upon return, make sure the unit has been off for 45 minutes or an hour before reoccupying the space. Unwanted odors will have been oxidized and the area will smell fresh. Note: The OdorFree also has a "Hold" feature on the Timer for really tough odors so that it runs until manually turned off.

The primary maintenance involves the ceramic plates, which need to be cleaned about every three months or so, depending on the environment and the amount of use. They are easily removable from the back of the OdorFree like a CD. So there is no need to disassemble the generator for cleaning, as with other manufacturers. Simply wash the plates with soap or a spray cleaner, then rinse and dry completely. Typically, the plates last 2 to 3 years depending on the environment and use. An optional filter is also included that helps keep the plates clean for a longer period of time. Replaceable plates and filters are available.

Air filters trap particles that are floating in the air onto a membrane as they are drawn into the filter. They normally do not have an impact on odors, but in some cases, certain gases can be trapped as well. An odor molecule must get passed through the membrane in order to be captured, so filters are unable to affect the source of the odors. Ozone generators on the other hand, send out O3 into the treatment area to oxidize and remove odors at their source.

Most deodorizers use a fragrance formulation to counteract odors combined with fragrances to help cover them up. The fragrances used in deodorization will normally leave some residue in the air and on surfaces. Some people find these fumes unpleasant, while those who are highly sensitive may have a reaction. Ozone, on the other hand, is designed to oxidize odors at their source. It usually dissipates less than an hour, leaving the air smelling fresh, with no residue. In fact, it will even eliminate the heavy smell that can linger from a deodorizer.

Since life began, ozone has been produced on earth as a result of sunlight striking gases being emitted from decaying matter, keeping the planet fresh. This is a response to pollution in the air. When automobiles and industry pollute the air in our cities, UV light from the sun strikes these emissions, creating ozone as one of the byproducts. Burning fossil fuel also creates very fine particulate as well as numerous compounds, but ozone is easy to measure and used as an overall indicator of pollution. Cleaner burning fuels, more efficient engines and exhaust reduction devices have begun to slowly improve air quality in many South African cities.
