A paper was recently published by the Journal of Infection Diseases and Epidemiology that is promoting the use of ozone as a treatment for the Corona virus. Worth a read for sure.
Many viruses require reduced sulfhydryl groups for cell fu-sion and entry. Corona viruses, including SARS-CoV-2 (the cause of the condition now named coronavirus disease 2019 or COVID-19), are rich in cysteine, which residues must be intact for viral activity. Sulfhydryl groups are vulner-able to oxidation. Ozone therapy, a very inexpensive and safe modality may safely exploit this critical vulnerability in many viruses, inclusive of SARS-CoV-2
Recently ozone has gained a great deal of interest in the news. There is a role for a powerful disinfectant like ozone to play in the fight against COVID-19. Due to this, the use of ozone is finally gaining some worldwide attention.
For your reading pleasure we have compiled a few of the recent news stories. Have more? Send them to us, we’ll add to the list.
We are not endorsing any of the claims made in any of these articles. We are however celebrating the attention given to the power of ozone as a viable disinfectant. We hope this new awareness continues long after the COVID-19 crisis has subsided.
The Coronavirus pandemic has sparked an exponential increase in interest in ozone as a disinfectant. The phones at Oxidation Technologies have been ringing non-stop with people looking for answers and looking for help with their grand ideas for ozone as a silver coronavirus bullet. Our ozone specialists have been working hard to provide accurate information for those looking for answers. Ozone has been a powerful tool for over a hundred years, but misinformation is dangerous in a climate of desperation and hype. Our goal throughout this health crisis has been to educate our callers about safe and unsafe uses of ozone, effective and ineffective applications of ozone, and the facts and false claims people make about ozone.
If there is so much interest in ozone as a powerful and chemical-free disinfectant, why do we read so much about ozone as a very bad and deadly pollutant? For example, the American Lung Association says “Ozone (also called smog) is one of the most dangerous and widespread pollutants in the U.S.” On the other hand, the Food and Drug Administration (FDA) approved the use of ozone as an antimicrobial agent for the treatment, storage and processing of foods in gas and aqueous phases.” For years, now, we have recognized the value of an atmospheric layer of ozone that shields “living things from too much ultraviolet radiation from the sun.” Ozone sterilization of water has made the bottled water industry possible providing billions of bottles of safe drinking water. The answer to this paradox is not difficult or mysterious, but does require some ozone education. We hope you take some time to explore the wealth of ozone information on our website.
At the time of writing, most major economies are entering into some form of lockdown, causing significant disruption to businesses and drastically changing the way we live our lives for the next few months.
Governments, Industry and Citizens are united in trying to slow the spread of COVID-19, to give health services time to prepare for the explosion in the demand for care. Sanitizing our homes, workplaces and public spaces is a key tactic in the fight against Coronavirus, to stop the spread of COVID-19. One method of sterilization is by using ozone. Ozone sterilization is commonly used in hospitals to sanitize equipment and significantly reduce or eliminate the spread of bacteria. Hence the question being asked is – “Can ozone sterilization kill the Coronavirus which causes the COVID-19 disease?”
blog post looks at the evidence and highlights the benefits of
sterilizing environments with ozone, as well as it’s associated risks.
OZONE STERILIZATION PROVEN TO KILL SARS-COV VIRUS
There are currently no examples in the public domain, of ozone sterilization being used to kill the current strain of Coronavirus, SARS-CoV-2
(technical name of the Coronavirus which causes the COVID-19 disease).
However, there are reasons to believe it would be effective:
As SARS-Cov-1 is also a member of the Coronavirus family, it is highly likely that ozone sterilization would be effective at killing SARS-CoV-2, the Coronavirus which causes the COVID-19 disease.
HOW DOES OZONE STERILIZATION KILL CORONAVIRUSES?
Coronaviruses are classified
as “enveloped viruses”, which
are typically more susceptible to “Physico-chemical challenges”. In
other words, they don’t like being exposed to ozone.
destroys this type of virus by breaking through the
outer shell into the core, resulting in damage to the viral RNA. Ozone
can also damage the outer shell of the virus in a process
called oxidation. Put simply, exposing Coronaviruses to sufficient ozone dose (ppm x time) can result in them being 99% damaged or destroyed.
WHAT ARE THE RISKS OF OZONE STERILIZATION?
even small amounts of ozone can be harmful. Symptoms include coughing,
shortness of breath, and aggravation of lung diseases like asthma. At
higher concentrations you can smell ozone, but it becomes harmful even
at lower doses. For that reason, many countries have set
an 8-hour exposure limit of 70 ppb (parts per billion) ozone. In the
EU the limit is set even lower. Ozone is one of six common pollutants
limited by the United States Environmental Protection Agency and other country’s Environmental regulators. Exposure to ozone in the workplace is controlled by the Occupational Safety and Health Administration and their counterparts around the world.
REDUCE THE RISK OF OZONE EXPOSURE BY MONITORING
ozone can sterilize coronavirus infected environments, residual ozone
could also cause respiratory issues for people who breathe it
in. To stop this from happening it is important to measure
and control indoor and outdoor levels of ozone after sterilization has

We have been getting many questions and interest on the use of ozone to help in the fight against COVID-19. The following is a statement released by the IOA (International Ozone Association) that gives great information on the current situation.
There has been a great deal of recent interest in the use of ozone to eliminate pathogens, and specifically viruses. Here is some brief info on the use of ozone to eliminate pathogens.
Ozone can be used to eliminate pathogens including viruses and bacteria. In fact, there are no known viruses or bacteria that are immune to the oxidation of ozone. The best method to harness the power of ozone is to dissolve ozone in water and use aqueous ozone. However, ozone in the gas form can also be used to eliminate pathogens.
Aqueous ozone activity against viruses
Several published studies have shown aqueous ozone to reduce infectivity of common viruses by more than 99.999% [Reference below]. Aqueous ozone inactivates microbes, including both viruses and bacteria, by oxidation of the cell surface and internal structures. This disrupts the microbe’s structure and pathogenicity. Enveloped viruses such as Coronaviruses are particularly susceptible.

Ozone Effect on Pathogens
As a biocide, ozone works similarly to chlorine (another oxidant) and is used in a similar manner. Ozone disinfects by directly oxidizing and destroying the microorganism’s cell wall, causing cellular components to leak outside the cell. This causes protoplasmic destruction of the cell, damaging constituents of the nucleic acids, and breaks the carbon–nitrogen bonds, which leads to depolymerization. During the process, ozone splits into oxygen and an ozone atom, which is lost during the reaction with the microorganism’s cell fluids, O3 -> O2 + (O).
Every day, pharmaceutical companies around the world produce tons of products that people use to enhance their quality of life. This realm of products has been lumped into a category called “Pharmaceuticals & Personal Care Products,” (PPCPs). These products and drugs do not disappear, but are found increasingly in the water being discharged from wastewater treatment plants. The impact that this cocktail of chemicals has on the animals and people dependent on this water is not fully understood, but the evidence is clear that it is not good.
Ozone is a powerful oxidant capable of breaking troublesome molecules. What impact does ozone have on PPCPs? A recent laboratory study published in the engineering journal of the International Ozone Association (IOA) exposed water containing thirty seven different PPCPs to investigate the degradability of these chemicals.
Eight of the thirty five were very quickly degraded to or below their limit of detection with a dissolved ozone dose of 1ppm within 5 minutes. Five more were degraded with a dissolved ozone dose of 2ppm within 5 minutes. Five more required at least 10 minutes of retention time at 2 ppm.
The other half of the thirty five required more time and a higher dose of ozone. Three of them, (DEET, Ketoprophen, and Primidone) did not degrade below their limit of detection even when exposed to 9ppm of dissolved ozone for 15 minutes.
Ozone clearly has a significant role to play with PPCP cleanup. Further study is sure to discover ways to optimize the process and make it more effective. Oxidation Technologies specializes in integrating ozone into the specific process of diverse customers. We continue to pursue a better understanding of ozone use in a variety of applications.

High quality ozone is worth its weight in gold. Ozone is increasingly recognized as an effective green alternative to disinfection chemicals. More and more of this valuable substance is being generated and used in the world. So if ozone is so valuable, why is an ozone
destruct unit integrated into most ozone generating equipment?
Ozone is valuable when it is in the right place at the right time. Dissolved in contaminated water, ozone will break down pathogens and harmful chemicals. Floating in the air we breathe, excessive ozone irritates our sensitive airways and begins to oxidize materials. Generated by ultraviolet light in the stratosphere, ozone shields the earth from harmful solar radiation. As a biproduct of breaking down automotive pollutants with solar energy, ozone adds to the discomfort of breathing stagnant air trapped around metropolitan areas. Responsible use of ozone ensures that this valuable resource stays confined to its location of use. Often this means that unused, diluted, and contaminated ozone is destroyed.
Destroying ozone is as simple as causing it to react and breaking back into oxygen molecules.
How does it work? Keep in mind that ozone is simply three atoms of oxygen bonded together with a lot of energy.
Each molecule is like a mousetrap that has been set. It doesn’t take much to trip the trigger, break the bond, release the energy, and fall back into the more stable two atom configuration we call oxygen.
Whenever ozone is being used in an application, the energy is being released to do the work desired of breaking down the compounds we need broken down.
Typically as the ozone reacts, the oxygen atoms bond with the broken parts of the molecule to form H20, C02, etc.
There are some substances that will break the ozone apart without being broken itself. A substance that does this is called a catalyst. That catalytic converter on an automobile is another example. A catalytic converter breaks down toxic gasses from combustion into less toxic compounds. One such substance that breaks down ozone is a mixture of manganese dioxide and copper oxide. This compound is manufactured by Carus Corporation under the name Carulite. It looks like dark brown gravel. It very effectively breaks ozone down to oxygen without being destroyed itself. It is non-toxic and will not burn or generate harmful gasses as a byproduct.
A very efficient and effective design is a stainless steel can shape with a pipe thread fitting on the bottom, and a flange to bolt a lid on. This design is very safe, long lasting, and easy to service. A stainless steel sieve at the bottom inlet side holds the Carulite about an inch from the bottom. This allows the ozone to flow evenly through the Carulite material above it. If the ozone is off-gasing from water or from any other wet source, this space at the bottom can be heated so that this moisture does not condense in the Carulite and shorten its life.
The catalytic action of breaking ozone down releases heat energy which is safely dissipated with the heavy gauge stainless steel housing. Virtually all the ozone is turned back to oxygen which flows from the top of the device.

The USA’s Florida Southern Gulf Coast has been experiencing a severe red tide algae bloom since November 2017.
This particular event is very strong, resulting in major fish kills and disagreeable air quality on the beach. Red tide is a type of toxic algae that naturally blooms almost every year in Florida. It often dissipates in a few weeks or a month or so. This particular bloom is very strong and has resulted in a state of emergency being declared for the affected areas. Because the tide causes breathing problems, tourism has been severely affected.
Scientists at the Mote Marine Laboratory, Sarasota, FL are conducting experiments to combat the spread of the red tide and prepare for future outbreaks. They are testing a process that
pulls red-tide-infected water from canals into 25,000 galloon tanks, treats it with ozone and pumps it back into the ocean. The initial experiments were successful in removing the red
tide and its toxins and the water chemistry returned to normal within 24 hours. This experiment was featured on several television news shows including CBS and PBS. On September 23, 2018, Florida Governor, Rick Scott approved a $2.2 million grant to Mote Marine Laboratory to
expand its ozone treatment systems and to conduct new field testing of a specialized clay focused on quelling red tide. The testing should start within a few months.
