Ozone is produced naturally through sparks and UV-Light, ozone is also produced commercially for many uses. This will outline a few methods ozone is produced.
Ozone is Produced Naturally from Lightening During Thunderstorms.
Ozone is Produced Naturally from UV Light from the Sun
These same methods of ozone generations can be used commercially for industrial ozone applications. Great advancements have been made in the ozone industry to produce ozone more reliably and efficiently.
Ozone Production from Corona Discharge
Oxygen flowing between an electrode and cathode produces ozone from a spark, more commonly referred to as Corona Discharge.
Ozone Production from UV Light
Ozone can be produced from a UV light tuned to the proper wavelength inside an enclosed chamber.
Ozone can also be produced directly in water using an electrolytic cell. This method uses a current within the water to split the oxygen and hydrogen atoms, then converts the oxygen directly into ozone. This is a fairly new commercial ozone generation method that may show great promise in the future. At this time, this application has very limited application.
Commercial Ozone Generation
Corona Discharge (electrical discharge field)
High voltage spark at medium to high frequencies
Creates ozone at medium – high concentrations (up to 22%)
Most commonly used
UV Ozone Generation (photochemical)
Low concentration ( max 2% concentration)
Small ozone outputs
Electrolytic
Currently only small outputs
Ultra pure water is necessary
The most common method of ozone generation is corona discharge. Due to the low operation costs, and improved reliability this will be the main method of ozone generation for many years to come, for more information on ozone generation watch for future installments of “How Ozone is Made“
Ozone Solutions has recently added a new ozone generator to our product line. The NANO Ozone Generator is manufactured by Absolute Ozone and is perfectly suited for lab applications where high concentrations of ozone are required.
The NANO Ozone Generator can produce ozone concentrations greater than 9% by weight from oxygen at flow rates of less than 1 LPM. When lab tests are performed on a small scale it is imperative to have ozone generated at the concentrations possible. Ozone solubility is dependent upon ozone concentration, this makes high concentrations of ozone extremely beneficial in any application.
The NANO Ozone Generator can be used for small industrial applications where the small size will come in handy. With the great efficiency of this ozone generator very low oxygen flow rates will still produce great ozone outputs. At only 3 LPM of oxygen 15 g/hr of ozone is produced with the NANO Ozone Generator.
With easy to use controls and a small compact size the NANO Ozone Generator can be useful for many applications. The low price of the NANO Ozone Generator opens up an entire new world of possibilities for our customers on a budget who demand the highest ozone concentrations possible.
For even higher ozone concentrations we still offer the HC-30 Ozone Generator. The HC-30 is capable of 12-14% ozone concentrations at very low flow rates. The NANO Ozone Generator is manufactured by the same company and with the same technology as the HC-30 at a lower price.
There are many practical uses for ozone in the world today. While no one ozone company can be experts at every ozone application we can try to provide useful information on many applications, and possibly point visitors in a direction to find the information they are looking for.
For information on the use of ozone for any of these applications or any others please contact our application engineers today. If we do not have the information you are looking for, we will be glad to point you in the right direction.
Ozone is increasingly used in aquaculture due to its numerous advantages over traditional water treatment methods. Supplementing or replacing an existing system, ozone implementation has the potential to boost the competitive advantage of your aquaculture application.
We were asked to provide the ozone production performance of the OZV-8 Ozone Generator equipped with the 10-position switch. I prepared an extensive performance chart for this customer showing the ozone output at each switch setting. I thought this chart was worthy of sharing.
It is interesting that the OZV-8 Ozone Generator produces ozone concentrations up to 4.77% by weight at 1 LPM. This is a great ozone concentration for this Ozone Generator. However, the overall ozone production with the OZV-8 peaks out at just over 8.5 g/hr of ozone. It is evident that higher oxygen flows will not improve ozone output. It was impressive to see how linear the ozone output was across each of the switch settings at each flow rate.
For more information on the OZV-8 Ozone Generator see the web-page here. For additional Ozone Generators see our entire Ozone Generator product line. If you have any questions about using the OZV-8 or any other Ozone Generators please call our application engineers today.
Ozone Trailers are built for Groundwater Remediation needs. The mobility, security, and simplicity of these systems are very useful for temporary remediation sites.
Ozone Solutions builds Ozone Remediation Trailers from the ground up. I thought it might be fun to show how this progresses!
Ozone Solutions has trailers custom built by, K&O Manufacturing, right here in Hull, IA. Using a local manufacturer allows a great deal of flexibility in our construction, and a higher quality end product for the customer.
These trailers have vents, an air conditioner, and many internal brackets built into the trailer during assembly. This allows the trailer to be painted after these holes are cut. These pictures show how the trailer arrives to Ozone Solutions.
The inside of the trailer is painted steel construction ready for assembly. There are braces installed for the divider wall, and vent holes cut in the back.
Looking in to the front door of the trailer. Plywood is now installed on the walls with insulation between the plywood and steel exterior. An insulated divider wall is also installed between the front and rear of the trailer. The roof is insulated and lined, with an air conditioner installed in the roof to cool all controls and ozone generating equipment.
Wiring is completed inside the trailer. This is a big task, however working inside a trailer allows great flexibility for the customer and for us to customize all controls for the specific application.
In the rear of the trailer, the Air Conditioner, Oxygen Concentrator, Oxygen Tank, and Air Dryer are installed.
The Ozone Generators are installed in the front of the trailer. The front of the trailer is divided from the rear of the trailer to keep the Ozone Generators, and other control equipment cool, clean, and dust free.
Completed front of trailer. For more pictures of the finished work, visit our website.
Completed trailer on site at a military base. More on-site pictures can be viewed on our website.
We now offer an alternative for calibrating larger dissolved monitors or to test dissolved ozone levels in a lab setting. The SAM-2 and the SAM-3 monitors are inexpensive dissolved ozone monitors that are both compact and reliable.
The SAM-2 has a range of 0.15-0.75 PPM, making it perfect for lab settings. No activator solution is required, which helps to cut costs. This monitor reads the ampoule that needs to be tested, and then will read a blank reference ampoule that is provided. If your ozone levels exceed its range, that is okay. Just dilute a fresh sample and retry the test! When you multiply the reading by the dilution factor you will have an accurate result. It is that simple.
The SAM-3 has a range of 0.20-3.00 PPM which makes it more appropriate for calibrating dissolved ozone monitors that are constantly in use (for example, an AS-500 on an ozone injection system). Using this analyte meter to calibrate your monitor monthly will help ensure accurate readings. This unit is also very simple to use – just zero it using the provided blank ampoule, and it is ready to test. This only needs to be done once (not between every test), which will speed up the testing process. After the unit is zeroed, you can test any number of ampoules.
You can get more information on these monitors by visiting the SAM-2 or SAM-3 on our website.
The Department of Agricultural and Biosystems Engineering at North Dakota State University has been doing some interesting research evaluating ozone as a possible antimycotoxin and microbiocide for small grains. Since grains contain a variety of micro-flora (bacteria, mold, etc), processors are careful to monitor micro-flora levels and take measures to reduce them before processing. Ozone is a simple alternative for reducing micro-flora that leaves behind no chemical byproducts to pollute the grain.
UND researchers have been evaluating ozonated water (ozone dissolved in water) for reducing micro-flora, and have results indicating that ozonated water could become a common cleaning agent in the grain industry as it has in the fruit and vegetable industries.
We are commonly asked about the uses of ozone. I want to help cover some of the basics of using ozone in water.
Ozone gas is dissolved into water for various reasons, these are just a few of the common applications of ozonated water. Click on any of the live links for more information.
Ozone gas is dissolved into water just as many other molecules can be dissolved into water. This may be for a variety of reasons. There are many methods of dissolving ozone into water, however, the following 3 are most common.
Bubble diffuser
The bubble diffuser is the oldest and most common method of dissolving ozone into water. Using a bubble diffuser is also the lowest cost injection method of dissolving ozone into water. However, this is generally the least efficient method of dissolving ozone into water. In many bubble diffuser applications much of the ozone is locked up in gas bubbles that rise to the surface of the water and escape completely.
Ozone Venturi
The ozone venturi, or injector as it is commonly refereed to is a very efficient and most widely used modern method of dissolving ozone into water. By using a pressure differential across a small orifice a vacuum is created on an inlet port. This inlet port can mix ozone with the water in a violent and very efficient method.
A static mixer can mix ozone with the water after it has been forced into the water stream by a direct injection port. This can be accomplished by increasing the ozone pressure to a higher pressure than the water pressure to force the ozone gas into the water stream. This is not a commonly used method, but does have some application. Static mixers can also be used after the Mazzei injector.
Ozone can be measured in water using a variety of methods. The following three are the most common.
Indigo
The most common and reliable is the indigo colorimetric kit that can be evaluated by visual or photometer methods. Common test kits can be purchased for this purpose. Below is an example:
The second is the inline method using electrochemical sensor cell with electrolyte solution. These sensors will use a sensor cell that is placed directly into your water flow, or a diverted water flow and give a real time dissolved ozone reading.
The indirect measurement of ozone is not widely used or understood. This method measure the level of ozone that has off gassed from the water and provides a calculated reading based upon Henry’s law. These sensors may take a sample, or be an inline real-time sensor.
