Ozone for SARS-CoV-2 inactivation on surfaces

The Journal of Hazardous Materials recently published a new paper on the use of ozone to inactive SARS-CoV-2, the virus responsible for COVID-19. The results aligned quite well with other work done on this topic with very comprehensive testing.

Abstract:

This study evaluated the inactivation of SARS-CoV-2, the virus responsible for COVID-19, by ozone using virus grown in cell culture media either dried on surfaces (plastic, glass, stainless steel, copper, and coupons of ambulance seat and floor) or suspended in liquid. Treatment in liquid reduced SARS-CoV-2 at a rate of 0.92 ± 0.11 log10-reduction per ozone CT dose(mg min/L); where CT is ozone concentration times exposure time. On surface, the synergistic effect of CT and relative humidity (RH) was key to virus inactivation; the rate varied from 0.01 to 0.27 log10-reduction per ozone CT value(g min/m3) as RH varied from 17% to 70%. Depletion of ozone by competitive reactions with the medium constituents, mass transfer limiting the penetration of ozone to the bulk of the medium, and occlusion of the virus in dried matrix were postulated as potential mechanisms that reduce ozone efficacy. RH70% was found plausible since it provided the highest disinfection rate while being below the critical RH that promotes mould growth in buildings. In conclusion, through careful choice of (CT, RH), gaseous ozone is effective against SARS-CoV-2 and our results are of significance to a growing field where ozone is applied to control the spread of COVID-19.

Inactivation rates of the SARS-CoV-2 virus were 99% or better in most cases. Both gaseous ozone and ozone in water were used with good results against the virus.

When using gaseous ozone relative humidity was also evaluated. As has been the case in other virus inactivation studies elevated humidity levels found higher rates of virus inactivation. In this test, humidity levels up to 70% were evaluated showing that realistic humidity levels can be used to achieve desired results but also leaving room for greater inactivation efficiencies with higher humidity levels.

Ozone effect on SARS-CoV-2 virus based on humidity.

The most useful information from this particular study was the effectiveness of ozone gas in inactivating the SARS-CoV-2 Virus on surfaces. Ozone was very effective in virus inactivation on both stainless steel and glass surfaces in a dried state.

SARS-CoV-2 inactivation by ozone on stainless steel and glass (100 μL of
virus solution in DMEM was dried on SS or glass then exposed to ozone at RH
81%, T = 26 ◦C, CT~15.0 g min/m3).

While the global pandemic caused by COVID-19 continues the research on how to combat the SARS-CoV-2 virus continues. We expect this will not be the last research paper reflecting great results on the use of ozone to destroy viruses.

Dissolve ozone into water with a Static Mixer

Read full and original article HERE

Ozone gas can be dissolved into pressurized, flowing water via a simple static mixer. Pressurized Ozone gas can flow into a water stream using a TEE provided the ozone gas pressure is greater than the water pressure. A downstream static mixer can then be used to thoroughly mix the ozone gas into the water.

Static mixer for ozone in action

Water should be pressurized when using a static mixer to aid solubility of ozone gas into water. Therefore, the ozone gas must be under pressure to force into the water flows. We have found that water pressure around 30 PSI is ideal for mass transfer, however higher or lower pressures can also be used.

Advantages:

  • – Simple, effective system design with no moving parts
  • – Great option for pressurized water
  • – More energy efficient than a venturi as a pressure differential across the mixer is not requied
  • – Easier to contain ozone gas and maintain a safe environment due to ozone off-gassing
  • – Can work with water that may plug or obstruct a venturi injector

Disadvantages:

  • – Higher risk of water back-flow into ozone generator due to pressurized water
  • – Requires flowing, pressurized water
  • – Greater risk of water backing up into the ozone generator as the water is pressurized

Ozone gas is partially soluble into liquid. However, using proper methods and equipment high mass transfer efficiencies can be realized with any method of dissolving ozone into water. Review the tips below to help design a proper system using a static mixer in your ozone application.

Fundamentals of Ozone Solubility:

     -Lower temperatures increase the solubility rate of ozone gas into liquid

     -Higher pressures increase the solubility rate of ozone gas into liquid

     -Higher ozone gas concentrations increase the solubility rate of ozone gas into liquid

Design considerations for your ozone system using a venturi injector:

Static mixer installation tips

  • Install static mixer shortly after the ozone injection point, within 12-inches if possible. Typically ozone bubbles will shear as they enter the water but combine again into a large air-pocket in the top of the pipe. Take advantage of the smaller bubbles as soon as possible.
  • If flowing water into a tank, install the static mixer within 12” from the tank
  • If flowing water into an un-pressurized tank, consider using an orifice to create back-pressure on the static mixer to improve solubility
  • Ensure proper flow-rate of water to achieve optimum water velocity for the mixer in use

Ozone Therapy in the news

Below is an excerpt and link to a recent news story on the use of Ozone Therapy. This new application of ozone continues to gain traction.

Full article HERE

OMAHA, Neb. ( KMTV) — Every medical innovation has its unique origin story, and ozone therapy is no exception.

The ozone itself has been around as long as the Earth, but it was first synthesized in 1840 by German chemist Christian Friedrich Schonbein, who identified it as the source of the smell in the air after a lightning strike. Ozone is a highly reactive gas composed of three oxygen atoms, and it is both a natural and a human-made product that occurs in the Earth’s upper atmosphere, according to the Environmental Protection Agency.

Medical ozone through history

By 1881, ozone was being used as a disinfectant and, in 1893, the first water treatment plant using ozone to disinfect and purify water for human consumption was built, according to the Spanish Association of Medical Professionals in Ozone Therapy.

During World War I, ozone was used as a topical application for infected wounds and an anti-inflammatory treatment, according to a clinical review of ozone therapy published by the Journal of Natural Science, Biology and Medicine.

Intravenous ozone therapy was developed and first used in Germany in the 1950s, according to Omaha Health Therapy Center.

“It is the most common medical ozone treatment today and is used by thousands of physicians worldwide,” according to the center.

How ozone therapy affects the body

Ozone therapy is an alternative treatment that practitioners use to take advantage of its various properties.

“Ozone has powerful anti-bacterial, anti-viral, anti-fungal properties, as well as the ability to neutralize toxins, boost the immune system and increase delivery of oxygen to all tissues,” according to Omaha Health Therapy Center.

Ozone therapy has been used to treat a variety of conditions:

  • Chronic fatigue
  • Circulatory disorders
  • Macular degeneration
  • Chronic bladder conditions
  • Heart disease
  • Wounds
  • Autoimmune disorders
  • Upper respiratory infections
  • Influenza
  • Hepatitis
  • Epstein-Barr virus
  • Herpes viruses
  • Lyme disease
  • Cancer

“In addition to killing viruses, destroying bacteria and eliminating fungus, ozone therapy supports many of the body’s basic functions,” according to Omaha Health Therapy Center. “One example of this would be activating red blood cell metabolism which leads to increased delivery of oxygen to the body and, because it helps to dilate constricted blood vessels, allows better blood flow. Ozone also increases the efficiency to the body’s own antioxidant system, helping to eliminate excess free radicals which are known to be the cause of many degenerative diseases.”

How to read a Venturi Injector performance chart

Read the original and full article HERE

The Mazzei Venturi Injector is incredibly predictable and reliable in the performance of liquid flow and gas suction. Using the performance chart provided by Mazzei allows for accurate planning and engineering of your ozone system. However, a proper understanding of this performance chart is necessary.

Mazzei Venturi Injector for ozone

Below is a chart for a common venturi injector. The injector is capable of mixing both liquid and gas into the main water flow through the venturi injector. For the purpose of dissolving ozone gas into water, the 3rd and 4th columns can be ignored completely as these refer to liquid suction only.

The first column is the injector inlet pressure, which is the pressure provided to the venturi injector inlet. The 2nd column is the injector outlet pressure, which is the pressure exerted on the injector outlet from delivering the water to the point of use. The 3rd column called MOTIVE FLOW states the flowrate of water going through the injector based on inlet/outlet pressures. This is what allows the proper pump to be chosen, calculate gas to liquid ratios and more. The last column called AIR SUCTION lists the amount of gas (oxygen,ozone, air), that can be sucked into the water stream at these aligned injector inlet/outlet pressures. As can be seen from the chart, as injector outlet pressure (2) increases, injector suction decreases (4). This is true even though the motive flow (3) stays relatively constant.

Dissolve ozone into water with Venturi Injector

Ozone gas can be dissolved into flowing water via a venturi injector. A venturi injector is typically up to 90% efficient and can be up to 99% efficient at dissolving ozone into water making this the most common and preferred method for ozone injection.

A venturi injector uses a pressure differential across a small orifice with an off-set opening and a suction port. Ozone gas is pulled into the water via the suction port of the venturi. Due to the pressure change and forces present the ozone gas dissolves into the liquid extremely quickly, and efficiently.

Venturi injector in action with clear pipe

To use a venturi injector water must be flowing and water pressure must be present with the ability to drop pressure at the discharge of the venturi injector. Water may already be flowing from another source to provide the flow and pressure, or a dedicated water pump can be provided to provide the flow and pressure needed for the venturi injector.

Mazzei venturi injector flow pattern

Advantages:

  • Extremely efficient
  • Great option for pressurized water
  • More ozone dissolved into water = less ozone off-gassing = safer environment
  • Easier to contain ozone gas and maintain a safe environment due to ozone off-gassing

Disadvantages:

  • Typically requires more energy than other options due to required pressure differential across venturi injector
  • Requires flowing, pressurized water
  • Greater risk of water backing up into the ozone generator as the water is pressurized
  • Venturi can plug or become obstructed in contaminated water

Ozone gas is partially soluble into liquid. However, using proper methods and equipment high mass transfer efficiencies can be realized with any method of dissolving ozone into water. Review the tips below to help design a proper system using a venturi injector in your ozone application.

Fundamentals of Ozone Solubility:

Sizing Venturi Injector properly

Venturi Injectors are available in a wide variety of sizes to meet a wide variety of water pressures and flow-rates. Using the right Venturi Injector for your application is paramount for a successful application.

Each Venturi Injector is provided with a performance chart showing the expected water flow-rate, water pressure, and correlating suction rate based on discharge pressure. Use this to determine the right size venturi for your water flow-rate and/or gas suction needs.

See our article HERE on reading Venturi Injector performance charts.

General Venturi Injector Installation Tips

  • Venturi injectors should always be installed in either a horizontal position or vertical position with the outlet above the inlet (water flowing upward). Never install with the inlet above the outlet as it may cause erratic suction
  • Always install piping after the venturi before flowing water into a tank. At least 12” of piping should be used at the venturi outlet
  • Never restrict the venturi outlet, consider using larger tubing at the venturi outflow than inflow as the pipe will be filled with both the water and added gas that has been pulled into the venturi.
  • For best performance target a 20 PSI pressure differential or greater between the venturi inlet and outlet
  • Install pressure gauges on tee’s directly at the venturi inlet and outlet to verify water pressures

Compare the Venturi Injector to the Bubble Diffuser

Compare the Mazzei Venturi Injector to the fine pore Bubble Diffuser to dissolve ozone into water

The two most common methods of dissolving ozone into water is the venturi injector and the bubble diffusion method. Each has it’s own advantages and disadvantages and applications where it might be best used.

History

Early ozone applications used large basins or tanks and bubble diffusers as the primary method to dissolve ozone into water. Ceramic diffusers were readily available and tanks or basins offered a simple and effective method to dissolve ozone into water. As ozone applications evolved and became more popular additional methods of dissolving ozone into water were investigated. In 1983 the Mazzei Injector company started producing special ozone compatible venturi Injectors specifically for the ozone markets. This brought the venturi injector into the mainstream ozone market from the smallest to the largest water flows and applications.

While the venturi injector can offer improved mass transfer efficiencies and smaller footprints there is still a place for the simple bubble diffuser yet today.

Advantages vs Disadvantages

Fundamentals of ozone solubility:

Bubble Diffuser Advantages: Low cost No moving parts Easy to setup Low energy – does not require water pumps or elevated water pressures Simple, reliable operation long-term  Venturi Injector Advantages: Extremely efficient ozone transfer Great option for pressurized water More ozone dissolved into water = less ozone off-gassing = safer environment Easier to contain ozone gas and maintain a safe environment due to ozone off-gassing Smaller tanks and overall footprint of the system can be achieved
Disadvantages: Ideal tank/basin depth for effective ozone transfer is 18-24 feet deep Ideal tank depths are not realistic in most applications causing this to be a less efficient transfer method. Diffusers can become plugged and may require periodic replacement Difficult to use in pressurized water flowsDisadvantages: Typically requires more energy than other options due to required pressure differential across venturi injector Requires flowing, pressurized water Greater risk of water backing up into the ozone generator as the water is pressurized Venturi can plug or become obstructed in contaminated water
  • – Lower temperatures increase the solubility rate of ozone gas into liquid
  • – Higher pressures increase the solubility rate of ozone gas into liquid
  • – Higher ozone gas concentrations increase the solubility rate of ozone gas into liquid

Sealed ozone tank with venturi injector Ozone gas dissolved into water in a sealed, pressurized system with a venturi injector.  Capable of dissolving ozone into pressurized water inline while safely capturing all undissolved ozone gas.

Design considerations in favor of Bubble Diffusers

  • Existing tanks or contact basins on-site whose height favors the bubble diffuser should be considered
  • Off-gassed ozone is more challenging to capture and handle with diffusers. If tanks are outdoors, or have proper venting in place already a diffuser may be a simple solution
  • Clean water applications where low dissolved ozone levels are required are well suited for bubble diffusers as high levels of ozone transfer are not needed.  

Examples of applications where Bubble diffusers may have an advantage:

  • RO water holding tanks
  • Bottled water applications
  • Well water applications with outdoor water holding tanks
  • Drinking water applications with large tanks or basins in place

Design considerations in favor of Venturi Injectors

  • If higher dissolved ozone levels are required a venturi injector is ideal as high transfer efficiency will be required to achieve these dissolved ozone levels
  • Varying water flow rates
  • Applications where pressurized water will have ozone gas added

Examples of applications where Venturi Injectors may have an advantage:

  • Sanitation applications where water is the carrier of ozone and high dissolved ozone levels are required
  • New construction water treatment applications where tanks are not already in place
  • Applications where footprint is a concern and space is limited
  • Well water applications where ozone will be added to water under pressure

SM-50 Discontinued – Why the OEM-3 is a great alternative

The SM-50 Ozone Controller has recently been discontinued. However, we are offering the OEM-3 Ozone Controller which is a great alternative. Below we will list some of the similarities and differences between the two ozone controllers to show you why the OEM-3 is a solid alternative. Please note – some of the data below also refers to the OEM-1 and OEM-2, more information on those products are also available on our website, but when it comes to a replacement for the SM-50, we highly recommend you check out the OEM-3.

The OEM-3 and SM-50 are both Original Equipment Manufactures (OEMs) Ozone Sensors that are designed with state of the art sensor technology that can be integrated into your own equipment.  OEM Sensors are a great addition to any Ozone System to help ensure any ozone leaks are detected and the Ozone Generation system is shut off.  The OEM sensors can be integrated into your system to control your Ozone Generation system and turn it off/on based on your preset levels. Below we will lay out the benefits and differences between the EcoSensors OEM-3 and the Aeroqual SM-50 OEM Ozone Sensors.

OEM-3

Mazzei Injector Co.: A 40-year overnight success story

One of the most important components of most ozone water systems is the venturi injector. The ozone industry has used Mazzei venturi’s since the beginning with the great support of Angelo Mazzei and his team at Mazzei Injector Company. I ran across this great article about Angelo Mazzei written from the perspective of a completely different industry. It’s worth the read.

Complete article HERE

Congratulate Angelo Mazzei on his 2021 Irrigation Association Industry Achievement Award and he’s likely to shift the attention to the support of his family and the employees of Mazzei Injector Company. Ask him about his 20 patents in fluid processing and he’ll probably tell you the story of how he ground away on the lathe in his garage to help solve a fertilizer mixing challenge on his uncle’s farm near Bakersfield, Calif.

With the improvements he made on venturi injectors in his garage workshop, Angelo Mazzei has changed the irrigation industry—and wastewater treatment, drinking water plants, even the wine industry—but he’s always quick to humbly point out that he’s a son of California’s Central Valley, a local boy with an engineer’s mind, a driving persistence, and a wife who encouraged him to follow his inventive instincts.

When the California Aqueduct piped water to his uncle’s 10,000-acre vegetable farm where Angelo Mazzei worked, it created vast opportunities, but also posed a challenge to irrigators who were accustomed to injecting fertilizer into reservoir water on the suction side of their booster pumps. The State Water Project delivered water at 20 to 40 pounds per square inch (psi)—enough pressure for sprinklers, but not enough for old-style venturi injectors to draw in fertilizer.

Drawing on an engineering class he’d taken at California State University, Fresno, Mazzei went to work in his garage to improve Giovanni Venturi’s brilliant technology. In Venturi’s design, fluid or gas is compressed in an intake cone, then allowed to expand in an outlet cone; the change in velocity creates a vacuum that pulls in other liquid or gas through a suction port.https://2c93de8848c61f9ca96d37d635eb2931.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

Mazzei adjusted the geometry and positions of the cones and suction port, dramatically reducing the amount of pressure differential required to inject fertilizer and mix it into irrigation water, making it possible for his uncle—and farmers around the world—to tap the power of the water itself.

A little challenge

“It was a little challenge to convince the patent attorney that a 181-year-old invention had any improvements,” Mazzei laughs. “I was really persistent because I thought I had stumbled on something that would be really beneficial for the irrigation industry.”

Beneficial indeed. Angelo and Mary Mazzei established their company in 1978, and sales of their venturi injectors took off as California farmers adopted drip irrigation. Mazzei soon turned to figuring out how to use his injectors to help a vegetable company aerate its wastewater lagoon to reduce odors. Over the years, his initial 1978 patent was joined by 19 more, representing advances in injection, mixing and automation in irrigation and other liquid systems.

Today, high-efficiency drip is common not only in the field, but also the foundation of indoor farming systems like greenhouses and vertical farms. Precision management of irrigation resources, process water and wastewater—as well as other inputs—will be even more vital to irrigated farms around the world, and automation is an increasingly important strategy as farmers struggle with tight labor markets. Think SCADA for farming.

More than fertilizer

Mazzei injectors have found applications well beyond fertilizer injection. Tiny Mazzei injectors treat spa water with ozone to protect bathers from pathogens. Massive ones inject air, oxygen or ozone for drinking water and wastewater treatment at huge municipal plants. And the sizes in between are used for injecting and mixing ozone for sanitizing and advanced oxidation processes in industrial wastewater treatment processes.

One of the most exciting recent applications of Mazzei injectors has been the development of the company’s AirJection system, which injects air into subsurface drip irrigation lines to aerate the root zone. Researchers around the world have demonstrated yield and quality improvements in crops ranging from melons to tomatoes to cotton.

And an innovative research team from Fresno State (Mazzei’s alma mater) and Memorial University of Newfoundland found that aeration significantly improves the balance of microbe genera in the soil, paving the way for improved nitrogen use efficiency.

Lifelong support of learning

Throughout his career, Angelo Mazzei has supported education. Dedicated to developing future agriculture leaders, he has contributed equipment, funds and technical expertise to California State University, Bakersfield, where he also serves on the foundation board; California Polytechnic University, San Luis Obispo; and University of California, Davis.

Mazzei has maintained particularly close ties to Fresno State, the school that helped him set the course for a life of innovation. There, he has been deeply involved in projects with faculty and students, and helped establish the university’s International Center for Water Technology.

Mazzei’s commitment to education extends to the lifelong learning provided by industry associations. He has been a member of the board of directors of the Kern Agricultural Foundation and an active participant in the Irrigation Association, California Agricultural Irrigation Association and the International Ozone Association.

Continued growth

Mazzei’s interest in lifelong learning drives his company, too. His daughter Celia Cobar joined the business, and as director of research and development, introduced computational fluid dynamics (CFD) modeling to the company’s capabilities. Mazzei Injector Company has developed dramatically since Angelo Mazzei’s days of experimenting in his garage. The ability to model the flow of liquids and gas inside the system and out has allowed Mazzei and his team to fine-tune injectors, pipeline flash reactors, gas separators, mass transfer nozzles and more.https://2c93de8848c61f9ca96d37d635eb2931.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

But despite all his technical and business achievements, Angelo Mazzei brings the conversation back to the people around him.

“My most proud accomplishment is building a company of dedicated people with great character to establish a culture of innovation, collaboration, service and uncompromising quality,” he says.
