Secrets - Most ozone generator manufacturers do not want YOU to know!


Here is something that is going to shock you a bit. A few weeks ago, I received a call from Bob, an engineer responsible for water treatment and disinfection at a large industrial plant. He was horrified, as he just purchased two 60 g/h ozone generators for $15,000 from a ozone generator manufacturer and they did not work.


He had done everything he was advised to do by the manufacturer’s specialist, but after running his ozone system for more than an hour, he was absolutely shocked when he found out he had only 4 grams of ozone dissolved in water out of 120 grams produced.


I told Bob, that it is not his fault and there is nothing wrong with his system. The problem is his ozone generators, which producing a respectful amount of ozone, had such a low ozone concentration level it was not suitable for water treatment.


I had revealed to Bob a connection between ozone concentration and amount of dissolved ozone in water.

We had replaced his two 60 g/h ozone generators with one high concentration 30 g/h generator on my advice, to illustrate the point. His system had successfully dissolved 16 g of ozone into the water - 4 times more ozone for a quarter of the price!

Ozone concentration is the key to

dissolving ozone in water, but

nobody wants to talk about it....

It is a secrets most air-cooled ozone generator's manufacturers do not want you to know.


Why do they not want you to know...?


Because most of the air-cooled generators on the market produce ozone at concentrations 1-3% by weight.

The truth is that at these concentrations it is almost impossible to dissolve any reasonable amount of ozone in water. In most applications, only 5-10% of ozone produced is being dissolved (or even much less) and that would mean that 90-95% of ozone will create off gas, which you will have to destroy together with the money you had paid to produce the ozone.




Because even a 3 wt% ozone generator vs. 6-7 wt% requires more than 2 times the oxygen to produce the same amount of ozone and dissolves less than half as much ozone into the water.


As an example, a 30 g/h ozone generator at 3 wt% concentration will dissolve in water about 10 g/h of ozone and will require 12.5 slpm (standard litres of oxygen per minute). A generator producing 30 g/h at 7.6 wt% will dissolve about 21 g/h and will require only 5.0 slpm of oxygen.


Simply put it means that if you buy an ozone generator, which delivers only 3-wt% concentration, it will cost you twice as much


If you compare two quotations in our above example, you will have the following results. To have 20g/h ozone dissolved in water you will pay:



This represents a total savings of $12,651!

If you want to start saving your money now, please select the right ozone generator for your water treatment application.

The highest ozone concentration on the world's air-cooled ozone generator market is available from Absolute Ozone®. At a lower gas flows their ozone generators offer concentration 18 percent by weight. (wt%)






Because, ozone concentration is one of the most important parameters of ozone generators. The websites of three of the world’s largest ozone generator manufacturers, will have phrases like; "All our ozone generators are capable of producing ozone with concentrations of up to 14 percent by weight (wt%) using oxygen"; "High concentration ozone generation maximizes efficiency and lowers operational costs" or "High ozone concentration is vital to high levels of dissolved ozone".


Typically, the percent of ozone concentration multiplied by 10 will indicate approximately the percent of dissolved ozone in the water.

I.E. 2% ozone concentration will allow you to dissolve about 20% of the ozone produced in the water.

 Because, more than 90% of air-cooled ozone generators sold in North America today, produce ozone concentration less than 3% by weight.

And their manufacturers will recommend using an air fed ozone generator for water treatment.  The main reason is that an air fed ozone generator is cheaper and therefore you are more likely to buy it. The other reason and they do not tell you about it is, that once you install the system you will start noticing that it does not work as well as you expected it to and when you complain, they will recommend that you purchase additional equipment to fix the problem. Since you are hooked, you will spend more money. Good for their business, but not so good for you.


There is also the maintenance cost of air fed ozone generators to consider. This usually involves the time consuming tasks of taking the ozone generator apart every few month, scraping deposits from the ozone generator electrodes, then putting it all back together, replacing damaged gaskets and other parts along the way.


The bottom line is that, unless you are very wealthy and enjoy cleaning and fixing ozone generators, do not buy an air fed ozone generator.

If you feel that you do not want to support mediocrity and wasteful technology with your money, choose the right equipment for your ozone application.




If you feel that I am biased, please read the following. It may convince you that there is more to it than my personal opinion.


The first issue is that air contains only 21% of oxygen and it is therefore impossible to create high concentration ozone. Typically, a good air fed ozone generator will not produce more then 1.5 wt% ozone concentration.


From the earlier explanation, you know that you will have a problem dissolving all of that low concentration ozone gas into the water causing most of it to "off gas" dissipating into the surrounding air versus dissolving into the water. Since ozone is highly corrosive you will therefore have to ensure that proper precautions are taken to destroy this ozone before it goes in to the air causes harm. This can be accomplished using a proper ozone destruct unit.


Another important disadvantage of air fed ozone generators is that the Nitrogen and humidity in the feed air creates calcium like deposits on the surface of the electrodes. Similar to a car, if you do not do preventative maintenance on the air fed ozone generator after a while these deposits will diminish your ozone production by restricting heat transfer from the plasma in the ozone cell. Heat destroys ozone and therefore the higher the temperature inside the generator the more ozone will be destroyed by it.  Interestingly, it is not uncommon that an air fed ozone generator will produce half as much ozone as when it was first used after only 6 months of use.

I ask myself a question, who are the real beneficiaries of this practically obsolete technology?

Of the ozone generators which do very little good and consume our resources, creating reputation that ozone is not efficient, is expensive, requires a lot of maintenance and is not reliable?


"Eureka! The companies which produce and sell chemicals. The companies, which keep our planet clean, by cleaning everything with chemicals. They are the winners.

And you can support them."



To summarize, my sincere hope is that the above information will help you to select the correct ozone generator for your application, to calculate the real operating cost of your ozone system, and to give you the background information you need to be able to ask the right questions when speaking with a sales person.


I am hoping that you will have many years of enjoyment from this wonderful ecologically clean treatment technology instead of many years of aggravations, troubles and disappointment and lost money.
