Control Dangerous Bacteria in Water with Low Levels of Dissolved Ozone

Legionnaires’ disease is a bacterial pneumonia caused by breathing mist from water containing the bacteria. The bacteria thrive in the warm water found in whirlpool spas, cooling towers, fountains, humidifiers, produce misters, etc. Symptoms of Legionnaires’ disease include high fever, a cough, and sometimes muscle aches and headaches.

The rate of reported cases has increased over 5 fold since 2000, and deadly outbreaks continue today unabated. The reason or reasons behind this increase are unclear at this point, but ozone has proven to be effective at controlling the bacteria in water. Whether the bacteria are flourishing within a 100 gallon fountain or a 1000 ton cooling tower, the engineers at Oxidation Technologies will maintain will provide the precise dose of ozone needed for safe water.

Ozone that is safely dissolved into water has a tremendous disinfectant power and simply turns back into oxygen after expending its energy. As little as 0.01 ppm (1 part ozone to 100 million parts water) prevents the growth of these bacteria. We provide cost effective equipment and long term service to ensure safe and effective use of ozone for bacteria control.

The equipment needed to dissolve low levels of ozone into water can be very cost effective and sustainable for many water systems. A home well-water system uses one of the smallest ozone generators we sell to dissolve enough ozone when the well pump runs to disinfect all the water needed in a typical home. As a general rule of thumb for industrial cooling towers, five grams of ozone per hour is needed for every 100 tons of tower cooling capacity.

The 50 g/h ozone generator needed to supply a 1000 ton cooling tower will also require an oxygen concentrator, venturi, ORP controller, and sometimes a booster pump. The oxygen concentrator and controller comes in a complete package with our OXG systems. The following study conducted by Mazzei reports a one year payback for ozone use due to lower chemical and cleaning costs.

We also provide the convenience of a quarterly preventative maintenance plan to make sure the system continues to perform at peak efficiency and avoid costly repairs due to neglected maintenance. We often work with an independent water company that provides routine testing for the customer to make sure water quality remains good and inform us of any problems.

Ozone gas used for ambulance disinfection

Product Applications from the Field: Providing a Cleaner Ambulance

Ozilla EMSWORLD SHOW 581376c7af441

I found an interesting article on the use of ozone gas for disinfecting ambulances.  This is interesting to me as I am a volunteer EMT in my local community.  While I appreciate that ozone gas can provide antimicrobial intervention quicker and more efficiently than most any other technology, I question how this applies to the field of EMS.

Question #1 – While the ozone generator is running in the ambulance one would not want to enter the ambulance.  However, we have no idea when the next emergency occurs that will require our services.  Do we have time to air out the ambulance?  Will the ozone level in the back of the ambulance be safe?

Question #2 – There are many rubber and plastic medical devices in the back of the ambulance.  How will these be affected by the use of high levels of ozone?  Using a cracked ambu-bag that will not hold air, or cracked oxygen tubing could certainly ruin my day.

EMS can, at times, be a messy profession. Some messes are much harder to clean up than others.

Products like the Ozilla EMS Sterilizer from Genlantis make cleaning and sterilization after particularly messy calls a simple task. 

The Ozilla EMS Sterilizer uses ozone gas, the most powerful oxidative agent that occurs naturally, to destroy germs, viruses and microbes that could linger and cause contamination after calls. The sterilizer leaves no residue typical of detergent or synthetic cleaners. The system kills 99.999% of 650 different kinds of pathogenic organisms in as little as 60 minutes.

Chad Panke, regional director of Gold Coast Ambulance/AMR Ventura County in California, says his company has been using the Ozilla EMS Sterilizer for about a year, and the system has given him peace of mind.

“The winning point is with blood and other bodily fluids: They can get into a lot of places we can’t see or might miss during the initial cleaning,” Panke says. “An area of big concern is what’s in the fabric of the seats, the first-in bag and the cloth straps of the gurney and backboard.  We don’t have to routinely soak them, which keeps them out of service for a long duration.”

Panke says the portability of the sterilizer is a plus, and it allows them to take the system to ambulances in the field in the case of a norovirus outbreak at a facility or something similar.

Another benefit is the ability to remove any smells after a call that might remain in the ambulance.

The Ozilla EMS Sterilizer is EPA registered and does not use any harmful liquids, UV rays, harsh chemicals or heat, and the ozone gas does not do any damage to surfaces inside the ambulance.

Better water on the way

Better water on the way with the implementation of ozone for disinfection

LIVERMORE — Prodded by long-term taste and health concerns about its Delta drinking water, the supplier for 220,000 Tri-Valley residents is adding a new water disinfectant more effective than chlorine.

Adding ozone gas — an estimated $30 million project — will produce better tasting water with lower levels of a known carcinogen, as well as several chemicals of emerging concern such as endocrine disrupters, says the Alameda County Zone 7 Water Agency.

The district is a relative latecomer to ozone. The disinfectant has been used for years or decades several Bay Area water districts, including Santa Clara Valley, Alameda County, East Bay Municipal and Contra Costa Water.

Last week, Zone 7 moved to join them. Its water board approved a $2.7 million design contract to draw up plans for ozone equipment at the district’s largest treatment plant. It will take at least three years to finish the installation, officials estimated.

“Ozone will improve our water quality,” said Jill Duerig, the Zone 7 district general manager. “We think it will help a lot in dealing with taste and odor issues related to algae and other organic materials in Delta water.”

The district supplies treated wholesale water to city and local water systems in Livermore, Pleasanton, Dublin and part of San Ramon.The Sacramento-San Joaquin River Delta — where Zone 7 gets its state water supply — is full of organic material and vulnerable to algae blooms. A recent Delta algae bloom resulted in many consumer taste complaints about Tri-Valley water until the last few days.

Ozone, a highly reactive gas, seeks out and breaks up organics that can impart bad smells and odors to drinking water.

Ozone also reduces the formation of disinfection byproducts called trihalomethanes that can cause cancer. The substances form readily when chlorine is added to water.

Zone 7’s concentrations of trihalomethanes is within public health standards, with not with as great a margin to spare as the district would like, Duerig said.

“There is no one silver bullet in water treatment, but this gives an important new tool,” she said.

Zone 7 has moved slowly to embrace ozone because of the high cost and the board’s historical reluctance to borrow money instead of funding new projects on a pay-as-you go basis.

With the ozone equipment planned, however, Zone 7 is looking into selling bonds and other financing alternatives to fund long-term projects.

The ozone project could raise Zone 7’s water rates about 3 percent, Duerig said.

Angela Ramirez Holmes was the only Zone 7 board member to vote against the ozone design contract.

She said Friday she is disturbed the district committed to spend nearly $3 million to design the project without knowing how it will finance the other $27 million of the cost.

“I think we should know the whole picture before we commit to a nearly $3 million down payment,” Ramirez Holmes said.

Ozone use for Wastewater Disinfection

Wastewater Disinfection

Ozone used for wastewater disinfection has the potential to lower/eliminate chemical additions into water providing for a green solution and save you money.  Ozone is a powerful oxidant that will provide excellent disinfection to any water stream.  The oxidation potential of ozone is greater than that of all other chemicals used for wastewater disinfection.

Ozone ws initially utilized for disinfection of drinking water starting back in 1906.(history of ozone use)  The use of ozone for wastewater disinfection did not gain attention until the early 1970’s.  By 1984 there were 43 operational municipal wastewater treatment plants utilizing ozone for disinfection in the United States alone.  However, the implementation of ozone in large scale municipal plants stagnated after about 1985.  This was due mostly to the low cost of chlorine, and the lack of regulation on chlorine residuals in water.

Ozone use for wastewater disinfection has again gained attention in recent years.  Ozone is again becoming cost effective and necessary for three main reasons.

  • Chemical costs have increased dramatically in recent years.  Handling costs, storage costs, and cost of the raw chemical have created a for a high cost for traditional chlorine and even chlorine dioxide.  This has allowed ozone to become a more cost effective solution.
  • Regulations are getting tougher to meet with traditional chemicals.  Regulations on e.coli, and coliform bacteria are becoming lower and lower in most every state in the nation, and even worldwide.  Combine this with lower discharge limits on residual chlorine.  This requires higher chemical usage for chlorine removal from water after disinfection.  These lower discharge limits for bacteria, and chlorine create an atmosphere where ozone is very cost competitive, and may be the only viable option for some treatment facilities.
  • Micro-pollutants, or Endocrine Disrupting Chemicals (EDC’s) are becoming a major concern in rivers and lakes where wastewater is discharged.  Ozone orAdvanced Oxidiation Processes (AOP) are proving to be the only viable option for removal of these contaminates in wastewater.

Add to these primary factors that ozone is a green technology that may reduce overall energy consumption and chemical residual in water and ozone looks very attractive for many plants.  Both municipal wastewater treatment plants, and industrial plants, such as meat packing plants have been investing in ozone systems for wastewater disinfection in recent years.

Ozone for fruit disinfection and storage for shelf life extension

Ozone system used for fruit and vegetable disinfection.  MET Ozone is trialing ozone in Germany to prove the effectiveness of ozone for applications in food processing and storage.

MET Ozone Experts widens its range of ozone gas and water-dissolved ozone generators and invests in agronomic research in cooperation with Agrisana Srl.

2014 was a positive year for MET, with many of its plants operating mostly in Italy, but also in Germany and the Middle East.

The hot an humid weather with temperatures above the seasonal average favoured the development of fungi and rot, which could be counteracted by stocking the produce in units with a low concentration of ozone.Using ozone has now been made easier and safer thanks to new sensors and alarms. There is no need for tanks because it is always generated according to demand and there are no residues.

The products that benefit the most from ozone gas are citrus fruit, stonefruit, small fruit, kiwis, melons, strawberries, tomatoes, chestnuts, potatoes… Ozone prevents mould from forming and slows down ripening. It also reduces bacterial loads and improves the appearance of fruit.

In Italy, the Ministry of Health recognised ozone as a “Natural sterilisation product” with protocol no. 24482 of July 1996 and, since June 26, 2001, the F.D.A. approved the use of ozone compatibly with human activities.

In cooperation with Agrisana Srl, the MET started a research project to study possible practical applications in the agricultural sector. Mr. Stefano Poppi explains that they came up with a revolutionary technology to sanitise the areas (greenhouses) where vegetables are cultivated. Experiments proved successful on basil, tomatoes, courgettes, cucumbers, lettuce, aubergines, peppers and beans.

Additional tests are being carried out to verify its action against insects (mites, thrips, aphids, whitefly, etc.).

Ozone nano-bubble water: a potential treatment for severe gum infections

Tokyo, Sept 12, 2014 – (ACN Newswire) – The study, published in the journal Science and Technology of Advanced Materials, by Shinichi Arakawa and colleagues at Tokyo Medical and Dental University and Japan’sNational Institute of Advanced Industrial Science and Technology, evaluated the bactericidal activities of ozone nano-bubble water – also known as NBW3 – against the two main bacterial agents that cause periodontitis as well as its toxicity to human oral tissue cells.

Their results showed that NBW3 can kill periodontal pathogens within 30 seconds of exposure, yet has only a minor impact on the viability of oral tissue cells after 24 hours of exposure.

Based on their in vitro results, the researchers conclude that NBW3 could become a valuable tool for treating periodontitis. However, since in vitro models cannot be directly compared to real-life clinical situations in which oral antiseptics are diluted with saliva, the authors recommend further research to determine the extent to which NBW3’s potency may be reduced by the saliva of dental patients.

Periodontitis is an inflammation of the oral tissues that surround and support our teeth – it is caused by bacteria residing in “biofilms” or dental plaque.

The traditional first step of periodontal treatment involves “mechanical debridement” (i.e. scraping away the dental plaque and dental calculus). Various antiseptics and antibiotics have been used to supplement mechanical debridement.

But antibiotic therapies have several significant drawbacks, such as the selectivity of antimicrobial action, possible development of resistant bacteria, and risk for adverse host reactions. For these reasons, the topical use of a low-cost, broad-spectrum antiseptic agent with low potential for adverse reactions is preferable.

One possible alternative is ozone (O3), which has strong antimicrobial activity against bacteria, fungi, protozoa and viruses, and does not induce microbial resistance. Aqueous ozone is highly biocompatible with oral tissue cells. However, ozonated water must be used within the first 5 to 10 minutes after production to assure its potency.

To address this obstacle, co-author M. Takahashi and K. Chiba developed a patented procedure to produce ozone nano-bubble water. NBW3 retains its oxidation ability for more than six months if protected from exposure to ultraviolet rays. Its high stability allows for the bottling and use of NBW3 as a disinfectant solution.

Ozone Disinfects hospital rooms

Emerging Hospital Room Disinfection System Should Save Billions

read full article HERE


Medizone International, Inc. . In what is believed to be an important first, an entire ward at a public hospital remains 100% free from MRSA for 6 months after a major outbreak is quashed – thanks to the introduction of a new hospital room disinfection technology.

ozone removes bacteria from hospital rooms

In early June 2013, seven patient rooms on a 14 room ward at Quinte Health Care’s Belleville General Hospital in Ontario, Canada were quarantined after being hit by a rapidly spreading strain of Methicillin-Resistant Staphylococcus aureus (MRSA). MRSA is one of the most common causes of serious staph infections acquired in hospitals, globally.

Dr. Dick Zoutman, Chief of Staff for the hospital, was quoted as saying, “On average we have had one or two new MRSA cases per month on the ward. This is in keeping with averages being reported within the health care system nationally. In June we noted a rapidly spreading MRSA problem on the ward that reached seven rooms over a short period of time. That is when we began using Medizone International’s AsepticSure® room disinfection system. It is the only system we know of that can actually eliminate 100% of infective pathogens with a single room treatment. We have learned that obtaining even a 99.9% bacterial kill is not enough, as the remaining 0.1% of bacteria immediately begin growing back causing the problem of infection to start all over again in a few short hours. What is more, AsepticSure is proven to kill bacterial spores that can lurk in hospital rooms for months.” Dr. Zoutman is also a co-inventor along with Dr. Michael E. Shannon of the AsepticSure system.

“The results were immediate. The MRSA was immediately and entirely eliminated from the ward. The AsepticSure system was straightforward to use and quick, with complete room disinfection occurring in an hour. To prove to ourselves that the AsepticSure system was working, we performed cultures of 120 surfaces of the treated rooms before and after the AsepticSure system was used. The results were amazing. Virtual complete elimination of all bacteria on the room surfaces after AsepticSure was used in the rooms.”

“However, the longer term effects were not fully appreciated until after a six-month follow up had been completed. Only then was it realized that not only had the rooms remained free of MRSA, no further cases of MRSA were noted on the ward during this period.”

Safe use of ozone disinfection

Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection

Source: Emerson Process Management, Rosemount Analytical


By John Volbeda, Wastewater Industry Manager, Emerson Process Management, Rosemount Analytical and Randy Hawkins, pilot plant engineer, Newport News Waterworks

Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks, located in southeast Virginia.

Newport News Waterworks constructed a pilot plant eight years ago that uses ozone in the primary disinfection process. For this pilot plant, Newport News selected Rosemount Analytical ozone measurement systems from Emerson Process Management. These analyzers are used for continuous measurement of ozone in the ozone contact basin. Based on the success of the pilot plant, the Harwoods Mill plant at Newport News switched from chlorine to ozone for its primary disinfection process in March 2002.

“Our pilot plant processes 50,000 gallons of water per day, where the main plant processes a daily annual average of 24 million gallons of water per day. The success of this pilot plant testing prompted us to also convert our Lee Hall plant to ozone. It will be completed in about six months. Upon completion, the total system will serve over 400,000 people,” said Randy Hawkins, pilot plant engineer, Newport News Waterworks. “With that many people in our community relying on us, it is important that we provide the best quality water possible. Making the switch from chlorine to ozone for primary disinfection was a critical step, and using ozone analysis instrumentation from Emerson enables us to continuously monitor the ozone process.”

Both surface water and some ground water sources can contain many different pathogens (bacteria, viruses and parasitic protozoa), some of which are potentially lethal. These water sources can be contaminated by these pathogens, so water treatment plants render these pathogens inactive through a combination of chemical disinfection and filtration.
