Ozone bubbles are used these days in several applications, but Ozone nano-bubbles can be used to purify water, improve the vitality of fish, animals, and plants. It could also contribute to solving problems associated with biology, medicine, and food in the future. The secret is behind the high surface area of the nano-bubbles, which provides high mass transfer rates compared to traditional bubbles.
Ozone nano-bubble technology can purify waste water from the polymerized toner production process by using energy derived from the bursting of fine ozone bubbles (below 300 nano-meters in diameter). Water treated through this technology can be reused in the production process, thus providing a closed water recycling system. In this case, the process will save noticeable amount of money and energy in waste water treatment of polymerized toner production.
Nano-bubble ozonation of oyster will eliminate 99 percent of the calicivirus in oyster. Ozone nano-bubbles are very effective and are a new horizon in ozone technology. Contact us today if you think this could be a very promising solution for your operation.

One of the common themes at our family gatherings is sharing of food from many homes and spreading common illnesses. It seems the week after Christmas the stomach flu and other ailments run rampant. If you feel your house is not home to bacteria, viruses, and pathogens that just don’t belong, we might be able to help.
Using this bottle is easy. Fill it with pure water, let the batter charge with the plug-in charger, and spray aqueous ozone on surfaces! This device uses an electrolytic ozone generator to produce ozone directly in the water and pray that water on surfaces.
Now you have the power to disinfect countertops, door knobs, even couch cushions or carpet. After all, after the ozone has killed all the bacteria it reverts to harmless water and oxygen!
This article is intended to answer, how do venturi injectors work to dissolve ozone into water? Ozone is a gas, therefore proper gas/liquid contact mechanisms are critical to efficient system design. A popular method for adding the ozone gas into water is through the use of Venturi Injectors. Venturi Injectors work by forcing water through a conical body. This action creates a pressure differential between the fluid inlet and outlet ports, which in turn creates a vacuum inside the injector body. This vacuum now allows the ozone gas to be added into the flowing water stream via the suction port on the injector.
Venturis require a constant pressure differential to
initiate ozone injection (15 PSI in this example).
Very high ozone mass transfer rate (up to 98% if pressurized, 50-70% w/out pressure)
Minimal maintenance required
More controlled & consistant over time
Works well in both pressurized and unpressurized fluid streams
Requires energy from a booster pump, or pressurized water supply to achieve the 98% transfer otherwise can give you 50-70%
Tiny air bubbles (white) can be seen mixed with the water.
Water, moving from left to right, through a conical body creates suction which pulls air/ozone into the water stream.
A very high liquid to gas ratio is required to achieve 98% mass transfer efficiency. In fact, the ratio required would
not be economical. Typical mass transfer efficiencies for Venturi Injectors are from 50-70% (without the use of pressure).
ALEXANDRIA, Va. — The Drinking Water Research Foundation has released the results of a review paper entitled “Microbial Health Risks of Regulated Drinking Waters in the United States,” according to a press release.
The paper compares the risk of public drinking water and bottled water using data from the Centers for Disease Control and Prevention (CDC), the Environmental Protection Agency (EPA) and presentations from a 2009 drinking water symposium at Yale University, the release reported.
According to the release, the paper explores the difference in quality monitoring, regulatory standards violations, advisories and distribution system conditions for tap and bottled water.
The key finding of the paper was that, “it is clear that as a consequence of the differences in regulations, distribution systems, operating (manufacturing) practices and microbial standards of quality, public drinking water supplies present a substantially higher human risk than do bottled waters for illness due to waterborne organisms.”
While tap water is regulated by the EPA, bottled water is regulated by the Food and Drug Administration (FDA), which is more stringent in regulations concerning lead, coliform bacteria and E. coli, according to the release.
The research is fascinating as it does refute other data claiming that bottled water is less safe than public water supplies. Below is an excerpt from the conclusion paragraph of the review paper:
A comparison of waterborne illness outbreaks reveals overwhelming evidence that the microbial health risks associated with drinking tap water are far greater than that of bottled water, with 195 million illnesses in the past 10 years for tap water compared to fewer than a dozen for bottled water
This research and information is good news for the bottled water industry that has been hammered by negative press in recent years. Hopefully the bottled water industry will use this research to help promote the benefit of drinking quality bottled water as opposed to public water supplies.
As you may know, ozone has been used in the bottled water industry for many years to provide safe, high quality bottled water. Read more about ozone in bottled water on our website here, and see below:
Bottled Water and Ozone
A fast-acting and effective treatment technology, ozone is now used in a variety of potable water treatment applications. Ozone treatment is becoming widely used for bottled water in North America — now the most rapidly growing market for ozone.
Ozone Benefits for the Beverage Market
Ozone is superior to any other disinfection method because of its high oxidation state.
Ozone allows for lower operating costs and reduces overall chemical costs.
Ozone is not typically associated with by-products, and naturally reverts to oxygen, so no taste or odor is associated after its use.
Ozone is generated on-site. Therefore no dangerous storage or handling is required.
The International Bottled Water Association (IBWA) suggests a residual ozone level of 0.2 to 0.4 ppm. This provides disinfection to both the water and the bottle.
Destroying bacteria instantly, ozone works faster than any other oxidant on the market!
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.

There are constant microbiological threats in our daily lives; unfortunately, our drinking water and the recreational water that we play in are not excluded from where these threats reside. Among those preying on unsuspecting humans is the protozoan parasite — cryptosporidium (crypto). Crypto is one of the toughest microbes faced in water treatment, however, by the power of the molecule, ozone can eliminate it.
Ozone, molecularly known as O3, is a sanitizer and is relentless in its attack of organic microbes (bacteria, viruses, cysts, etc). Through a process known as lysing, ozone breaks down cell walls or membranes, where it can then destroy the nucleus of the microbe. In addition to sanitation, ozone is well known for the oxidizing of inorganic material that could be present in water, such as metals (e.g., iron and manganese). Although there are a few stronger oxidizers, ozone is the strongest that is readily available for commercial or residential use (see Figure 1). In fact, it is 1.5 times stronger than chlorine and many times faster acting. While leaving no off tastes, chemical by-products or residues, ozone is widely used in bottled water plants, wineries, breweries and food processing plants all over the world. Furthermore, because of this higher oxidation strength, ozone cannot build up a tolerance to microbes unlike other sanitizers, such as chlorine.
Did you know the most common industrial use for ozone is drinking water?
If you are new to the world of ozone it may surprise you how prevalent the use of ozone is throughout the United States. Today, there are more than 280 major water treatment plants in the United States that incorporate the use of ozone in their processes. It is projected that by 2015 the number of plants using ozone will reach 300. There is a very good chance that the water you are drinking has been treated with ozone prior to your consumption.
Ozone use in drinking water has has been prevalent throughout the world since the early 1900’s. Ozone was initially used in the United States in 1940 in Whiting, IN for water disinfection in the water treatment process. From there, the use of ozone in drinking water has expanded to its’ current wide usage throughout the United States today. In 1982, ozone was given GRAS approval for use in bottled water. This opened up the use of ozone for disinfection in the bottled water industry. Today, the majority of bottled water companies use ozone to ensure pure water that is pathogen free for consumers.

Looking ahead, ozone may also be used for the removal of micro-pollutants, such as pharmaceuticals in the water, personal care products, and endocrine disruptors. Ozone is currently used in waste-water disinfection for these purposes and it is possible the use of ozone will be carried over into drinking water plants in the future.
A few examples of large U.S. Cities using ozone today are below:
Carol Johnson, a spokeswoman with the National Park Service, said officials had made attempts in the past week to remove the algae, which began showing up in the pool about a week after its reopening. Johnson had said earlier that the Park Service expected a “break-in period” for the pool, but no one had anticipated the amount of algae that appeared.
The amount of ozone, which neutralizes the nutrient food for the algae, will be doubled. That should keep the algae from reappearing, Johnson said.
Previously, draining the reflecting pool has taken up to three weeks, but Johnson said Park Service officials think it can complete the work in a shorter time.
The cost of draining the pool and removing the algae is estimated at $100,000 and will require 65 contractors along with Park Service staff members working full time to complete it, Johnson said.
Access to the reflecting pool will be limited.
“This is a new state-of-the-art system, so there was going to be some trial and error involved,” Johnson said. “But we’re confident the higher ozone levels will work.”

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.
