We just added a few great products to our Ozone Classifieds. There are always great deals to be found here, but we wanted to specifically point out a few recently added great deals for you. See below to view the used ozone equipment available on the Ozone Classifieds.
This Gardner Denver PSA air dryer could be used to provide dry air for the CFL-5 Ozonia ozone generator. using this air dryer could provide up to $2,450 g/hr of ozone from dry air. This is the air dryer that was used with the CFL-5, so it would be a great fit. This could be a great deal on a large ozone system for your application!
The CFS-2G-3 is the updated version of the CFS-3A ozone generator. This generator uses 3 cells placed vertically inside the ozone cabinet. The CFS is a water cooled ozone generator that can produce ozone at up to 10% by weight. This could be a great ozone generator to use with the AS-D, or OG-50 oxygen concentrators.
We have an older off-brand stainless steel injection system available for sale at a great price. We have no use for this system at this time, but it could make a great system for someone, or a great starting point. This system has a stainless tank, stainless enclosure, and stainless skid. Those major components alone are worth the $2,500 price. However, this system also produced ozone and dissolved ozone in water. See image below:
This article is intended to answer, how do bubble diffusers work to dissolve ozone into water? Ozone is a gas, therefore proper gas/liquid contact mechanisms are critical to efficient system design. Bubble diffusers are a popular, inexpensive method to inject ozone into water. The ozone gas transfer area occurs immediately at the interface between the ozone bubble surface and the surrounding water.
Diffusers permit ozone gas to pass through a porous membrane thus creating many small ozone bubbles in the water, similar to a fish tank air stone. As the ozone bubble rises, the gas at the bubbles edge will transfer into the water. Using a diffuser requires enough pressure to overcome the height of the water and any restrictions in the diffusers due to hole size.
Easy to setup
Low energy – does not require a water pump
Inefficient – ranges from 10-25% (dependent on water height)
High water columns/vessels are typically required
Difficult to use in pressurized water flows
Diffuser pores can become plugged requring cleaning
- The diameter of a gas bubble has a dramatic impact on
surface area as shown below!
- Be picky when it comes to selecting a bubble diffuser. It can mean the difference between success and failure.
- The transfer of ozone gas into water is directly related to its surface area (total bubble surface area).
- It is critical to prevent the water from back-flowing through the bubble diffuser and going into the ozone generator. The best method of prevention is to use multiple check valves (for redundancy) and a water trap .
4.8 square ft. Dia. = 14.8 in. 1 bubble
185 square ft. Dia. = 10 mm. 54,000 bubbles
1,800 square ft. Dia. = 1 mm. 54,000,000 bubbles
Conclusion: Additional smaller bubbles give you more mass transfer!

Ozone solutions rents ozone equipment for a variety of applications. We offer a wide variety of ozone systems available for rent. Our largest systems are very popular and we normally keep a waiting list of customer. At this time we do have a WIS-300 ozone injection system that is available for rent. This is a 300 g/hr ozone generation system that also dissolves that ozone gas into water.
We also offer larger and smaller ozone systems for rental and purchase. At this time we are working on refurbishing a large 5,000 g/hr ozone generator for rent, and a few oxygen concentrators. We usually have small ozone systems available for rent on-hand, however our larger systems, like this WIS-300 are usually not available on short notice.
We also have an RMT-200 remediation trailer that will be available in the next few months. This system is used for in-situ groundwater remediation. This rental trailer will produce 200 g/hr of ozone and provide that ozone with sparge air through up to 30 well outputs.
Ozone Spray Bottle that produces ozone on demand to sanitize and disinfect
Producing dissolved ozone on demand is exactly what this new unit does in a compact, easy to use spray bottle. Simply add clean water to the reservoir, spray the surface that needs to be sanitized, wait the required amount of time, and wipe or let the air dry. This unit runs on batteries and produces ozone with a tiny electrolytic cell. Ozone is a powerful oxidizer and is often used in place of chlorine to sanitize and disinfect, and is environmentally friendly, as it reverts back to water and oxygen. See the chart below for the Microbial Efficacy Testing that was done by the manufacturer, Franke Foodservices, to know the time required to reduce different types of bacteria.
Ozone Solutions recently posted several new listings to our Ozone Analyzer section of our Ozone Classifieds. We now have over 15 used analyzers listed for sale. If you are looking for accurate ozone measurements at a low cost this is the place for you!
Below is a sample of the great deals on used ozone analyzers we currently have for sale on the Ozone Classifieds at this time:
Occasionally our customers will need to measure levels of ozone greater than 3 ppm with their K-7404 Dissolved Ozone Test Kit. To do so, the sample can be diluted, allowing up to 6 ppm of indication.
The video and instructions here, in combination with the standard kit instructions, will allow you to do this in the most effective way possible.
1) Add 5 drops of A-7400 Activator Solution to the sample cup.
2) Add 12.5 mL of distilled water to the sample cup.
3) Add enough sample to the cup to bring the volume to the 25 mL mark
4) Snap the ampoule in the cup, and continue with the standard instructions.
Find the result indicated by your comparator and multiply that value by 2.
The number you get is your dissolved ozone concentration.

Ozone Solutions has created a new video that illustrates proper use of our K-7404 Dissolved Ozone Test Kit. If you are curious about how these vacu-vial test kits work, this video will walk you through the process and show you the simple steps involved.

This Ozone Journal is a blog managed by the employees of Ozone Solutions. The purpose of this blog is to inform and educate the readers about the world of Ozone, provide news about the ozone industry, and have an easy opportunity to inform about new ozone products.
Check back often, ask questions, and let us know if there is anything you would like to hear about.
What is ozone?
Ozone is an oxidant. Ozone (O3), sometimes called “activated oxygen", or "triatomic oxygen", contains three atoms of oxygen rather than the two atoms we normally breathe. Ozone is the second most powerful oxidant in the world and can be used to destroy bacteria, viruses, and odors.
Ozone is a gas at ambient temperatures and pressures with a strong odor. Ozone can be produced as a gas from oxygen in air, or concentrated oxygen. This ozone gas can be dissolved into water, or used in the gas phase for a variety of applications discussed in this Journal.
