Ozone Disinfection for Drink Dispensers最先出現在百特集團 | 中文官方網站。

]]>
Many restaurants and bars use refrigerated drink dispensers to save costs on beverages while offering cold and refreshing beverages to their guests. Beyond the food and beverage industry, however, are movie theaters, schools, and hotels, which also use drink dispensers to keep customers’ cups filled. Ensuring these drink dispensers are clean and maintained is important to the health of people being served, and also important for the long-term use of the machine. 

Thanks to advances in ozone generation technology, disinfecting drink dispensers with the powerful oxidizing power of ozone has become a smarter option for many of these businesses. Ozonated water is safe and effective in keeping drink dispensers at your business free of harmful bacteria and free from unwanted chemical residues leftover by conventional cleaning chemicals. For more info on the advantages of cleaning with ozone, read our article: How Ozonated Water Works

Why ozone for drink dispensers?

Thanks to the reactivity of ozone on a molecular level, the O3 molecule begins breaking down almost instantly after being generated in the water supply. This leaves behind only clean, fresh water, and regular stable oxygen. Ozone’s reactivity is also why ozonated water is most effective as a disinfectant if it is used within the first five to ten minutes after being generated. For more info on how ozonated water is created, check out our article (link). 

While most quality drink dispensers are used seven to ten years on average, they must be cleaned regularly for a business to get the most out of their purchase. With ozonated water, these machines can be kept running constantly clean for customer safety and giving peace of mind to business owners. 

How to clean a drink dispenser with ozonated water

Below are basic instructions for how to integrate the power of ozone into the cleaning routine for your business’ drink dispenser(s). 

1. Daily Cleaning

The dispensers, nozzles, drain area, and external surface of the drink dispenser should be cleaned at least once at the end of each business day. Turn off the machine before disassembling the pieces from the front of the machine.

For basic daily cleaning, the nozzles, as well as any diffusers, which add the drink’s syrup to the carbonated water, should be detached from the machine. With ozonated water available on-premise, we recommend a two-part disinfectant process.

For plastic or metal nozzles and diffusers, they can be submerged in a plastic tub of active ozonated water from the Water Disinfection System (WDS) and left to sit for two to three minutes. Meanwhile, with an Ozone Spray Bottle (OSB) full of active ozonated water and a clean cloth, an employee can wipe down the exterior face of the drink dispenser. They should pay close attention to the drain area and the area around where the nozzle connects to the machine.

Any containers on top of the machine should also be disconnected and wiped down inside and out with the ozonated water solution. Give all implements several minutes to air dry before re-assembling the machine, making it ready for immediate use at the start of the next work shift. 

2. Weekly beverage line cleaning drink dispensers

Each week, it is recommended that any tubes supplying beverages be disconnected and thoroughly sanitized. This can be done by switching the water source to the ozonated water pipeline supplied by the PFDS series. Fill the entire pipeline and the equipment with ozonated water through the water discharge of the equipment, and switch the water source back to the beverage dispenser after the sanitation is completed. 

3. Monthly Cleaning

It is also important to clean the ice tray and ice dispenser, along with other parts of the machine at least every four weeks (or more frequently). Typically an ice machine may need to be deep cleaned every four to six months to ensure the ice cubes consumed by customers reach a proper hygiene standard. Using the IDS (Ice Disinfection System) by Biosure will make this process easier, as you only need to deal with the problem every half a year. This helps reduce the costs of labor, time, and money when deep cleaning if the ice machine is required.

Benefits of Ozonated Water

Some top-of-the-line water dispensers are even integrating ozone generation as part of the machine’s cleaning system. The ozone in the water supply will quickly dissipate and poses no threat to people drinking from the water dispenser provided the ozone is given sufficient time to break down, and not even affect the taste. 

In addition to the power of ozonated water as a potent anti-bacterial agent, in the long term, business owners will save money and space that would have been used on purchasing and storing cleaning chemicals. Using ozone as a cleaning agent will contribute to your business’s commitment to sustainability.

A business’ drink dispenser can be an important tool for promoting the public image of a business. This is especially true if the machine is located in front of the house for self-service by customers. While style and service capabilities are always important, cleanliness, both internally and on external surfaces, is no less important to the image a business provides to its customers. With the power of ozone-generation technology, there is no need to worry about the cleanliness of your equipment or the health of your customers being compromised ever again.

Keeping Your Beer Line Safe and Clean with Ozone最先出現在百特集團 | 中文官方網站

]]>
More than 27 billion pints of draft beer are consumed worldwide every year, and anyone who loves beer will choose it fresh from the tap over canned or bottled. Freshly pumped beer just tastes better – but only when the line from the keg and coupler to the tower is clean.

Unclean beer lines can not only ruin the taste of beer but also put customers’ health in danger. Dirty dispensers can make customers sick or even seriously ill. There have been incidents where customers have fallen ill after drinking contaminated beer at bars and restaurants — a nightmare scenario for a bar or restaurant owner. Chemical burns from caustic cleaning agents have also been an issue, resulting in lawsuits. Incidents like these can cost a considerable amount of money in medical and legal fees and, just as importantly, can cost your reputation. As a customer, we should never feel that our health might be in jeopardy for enjoying a cold beer.

Running the Risks of a Dirty Line

Dirty beer not only tastes terrible, but it’s also dangerous to drink. Contaminants such as bacteria, mold, and yeasts can build up in beer lines over time. Limescale and beer stone make beer muddy, while mold and bacteria can leave beer sandy, stringy, and even toxic. People have reported getting sick after having a sour pint at a bar. Guests are likely to write the bar off if they had consumed a beer pumped through a dirty line.

The Dangers of Chemical Sanitization

Most bars and restaurants know the importance of regularly cleaning their beer lines. But while most local health codes stipulate the frequency of cleanings needed, not all of them outline cleaning methods or best practices for cleaning equipment. In many cases, this leads to draft beer system owners using chemical sanitization methods. Without caution, unsafe chemical sanitization can also be deadly to your business and your customers. Consider these cautionary tales:

  • A woman in Massachusetts was burned by the acidic solution used to clean beer lines that a distributor failed to clear thoroughly after using it to clean the beer line.
  • In 2017, a brewery lost USD $750,000 jury verdict because a man fell dangerously ill right after consuming toxic beer from the brewery. He was then hospitalized for 6 days and lost 25 percent of his stomach lining. They later determined the cause was acidic chemicals that the brewery used to clean the beer lines.

There are many more “hot beer” horror stories like these and they are all too easy to find. In fact, many companies set aside around $15,000 USD each year to settle lawsuits from chemical burns. 

Using chemical solutions to clean pipelines means employees need to be extra thorough when rinsing off the residuals left by the cleaning process. This is time-consuming and leaves room for human error. Pub and restaurant owners stand to lose valuable business during chemical sanitization processes.

The Powers of Chemical-free Ozone Sanitization

Ozone is a natural molecule that can oxidize everything it comes in contact with. When oxidized, harmful microorganisms and chemicals break down into harmless compounds. This oxidation ability makes ozone the most effective disinfectant available for sanitizing drinking water and food preservation.

Using ozone beer line disinfection systems help prevent lawsuits through chemical burns that customers incur when bars and restaurants use toxic cleaning agents. Not only this, but ozone disinfection for beer lines saves staff time, money, and effort. Electrolytic ozone beer line disinfection systems run on only electricity and tap water. Using electrolytic ozone beer line disinfection systems means bar owners don’t need to manage a cleaning crew or spend extra money cleaning up dangerous chemicals.

When implementing ozone disinfection systems, bar staff do not need to close or pause the beer supply. Ozone turns into harmless oxygen as soon as it gets into contact with contaminants, leaving no harmful chemicals in the beer. Guests can enjoy a tasty brew with peace of mind while the tap keeps pouring — a win-win for customers and pub owners.

The Best Beer Line Disinfection System

The BioSure ozone cleaning kit (OCK) uses patented Electrolytic Ozone Generation to produce high-concentration ozone from water. BioSure makes sure you serve safe beer in the most efficient and affordable way to customers.

How BioSure Professional Sanitizes Beer Lines

BioSure’s OCK pumps ozone to your beer line to eliminate contaminants before serving to your customers. The BioSure OCK is optimized in many ways to ensure that it is:

The Safest

The Fastest

The BioSure system takes only eight minutes to complete. Because the process produces no chemicals, the OCK can sanitize beer lines multiple times a day without interrupting the beverage supply.

Cost Effective

BioSure systems only need minimal water and electricity consumption. Therefore, it is one of the most affordable options and a quick return on investment.

The Easiest

Bar owners don’t need to use additional cleaning tools or chemicals with the BioSure system. There are three different sanitation programs in the system which are specifically designed for cleaning beer lines and beverage machines.

Top Quality

While keeping your beer safe for consumption, BioSure eliminates the use of undesirable chemicals and the creation of by-products during sanitization and ensures the delivery of clear beer at its best quality and taste.

Drinking It All In

Tainted beer is harmful to your customers and your business. Regular cleaning for your beer line is essential. But choosing and implementing sanitization is crucial. At best, bar owners lose customers; at worst, you would be responsible for someone’s life. Choosing the right disinfectant system for beer lines is critical. Ozone is the safest, most affordable, and easiest way to sanitize your beer line over the long term. Ozone sanitization is also time-efficient and does not interrupt your beer supply. The system is easy to use, and it cleans beer with no chemical residuals. Using just water and electricity, you can serve the best quality beer in town. Cheers!

Ozone for Use in Laundromats – What makes cleaning with ozone different?最先出現在百特集團 | 中文官方網站。

]]>
As research on ozone increases and ozone technology becomes more accessible, many industries are applying this technology with great results. Some businesses looking to get the benefits of ozone’s disinfection power are laundromats and professional laundry businesses.

Ozone has been used for washing clothes for over a decade. It is especially favored at hospitals where sanitization is an absolute priority, and at fire departments, to remove strong, stubborn odors from used firefighter uniforms. In recent years, gyms, nursing homes, and privately owned laundromats have begun implementing ozone cleaning systems, with real results for both business owners and their customers.

What makes cleaning with ozone different?

In a traditional laundromat without an ozonated water generator, a wash cycle for an industrial-sized washing machine may include hot water along with alkali, detergent, acid, and bleach. Depending on how much and how many chemicals are used, there may also be several rinse cycles as well. 

With ozonated water injected into the wash, the need for chemicals is reduced. Furthermore, the ozonation process is just as effective with cold water, which means there’s no need to spend on electricity to heat the water for the wash cycle. Although many laundromats provide detergent to their customers, the ozonated water generator can neutralize microorganisms and break up soil deposits in the fabric. 

How does ozone work for laundry?

Ozone is an effective sanitizing agent because of its chemical nature. Ozone, or O3, is a reactive gas that will react naturally and immediately with most substances. As a type of “reactive” oxygen with an extra O molecule, it will instantly react with organic matter, such as bacteria, mildew, or mold. This results in the near-instant neutralization of the microorganism. 

When it comes to washing clothes, the ozone, which is dissolved directly into the water throughout the wash cycle will leave clothing clean, soft, and completely odor-free. 

How does an ozonated water generator system work? 

There are several ways to put ozone gas and water together. At BES Group/BioSure Professional we use three of them: venturi, spray contact, and self-priming pump. For professional laundry ozone systems, the self-priming pump is used because it has a higher rate of efficiency in producing ozonated water, and provides a higher volume of ozonated water from the system. This means it can produce a larger flow rate of ozonated water to ensure clothing and linens are properly disinfected. 

What are the benefits?

An effective ozone system gives customers peace of mind by preventing cross-contamination caused by bacteria from other customers. Secondly, it leaves a fresh smell at each wash, eliminating mildew odors. Overall, there is a better wash resulting in fresh and clean linens.

Additionally, there is no longer any need to maintain stores of chemicals to wash clothing and bedding. With fewer chemicals, that also means there is less need for multiple rinse cycles. With ozonation, the wash and rinse cycle are essentially combined into one. Increased use of ozone systems will do a lot to reduce water consumption throughout society.

Since there is no need to heat the water in the wash cycle to activate the cleaning chemicals, businesses will also save money on energy spent in heating large amounts of water — a substantial cost. After installing their ozonation system, some laundromat owners have reported a 40 to 50 percent reduction in monthly utility costs. Customers also benefit from the ozonation system in more ways than one. First, fabrics come out thoroughly sanitized. Secondly, the amount of time it takes to wash a load is reduced, which will save customers time waiting for loads to finish. 

And last, ozone has natural fabric softening qualities. This is thanks to its effectiveness at breaking down calcium, which can build up in washes over time. The reactive nature of ozone also helps break down other hard deposits in the fabric, whether from sweat, deodorant, or soil. In combination with the shorter wash cycles, ozone washes will ultimately increase fabric life. 

Ozone laundry is a win-win

Thanks to numerous benefits to customers such as improved wash quality and cost reductions to business owners, ozone for professional laundry is a no-brainer. Many traditional laundry businesses will continue to use a mix of chemicals to wash and disinfect laundry, but ozone systems are becoming the new standard and will eventually replace chemicals in the laundry cycle. As a business owner, your wallet will thank you for it, and as a citizen of the world, the Earth will as well.

Ozone Spray vs 75% Alcohol for Sanitizing最先出現在百特集團 | 中文官方網站。

]]>
Since the beginning of the COVID-19 outbreak, 75% alcohol or isopropyl alcohol spray has been one of our best friends for sanitizing our hands after handwashing. It effectively kills viruses by breaking the cell wall and eliminating the threat. Similarly, ozonated water can serve many of the same functions. It is used in hospitals and dentist offices, as well as in the food industry — for disinfecting water and surfaces. Thanks to ozone’s efficient oxidizing rate, it works in seconds and leaves behind no chemical residues.

This makes ozone spray a great choice for disinfection in spaces that are prone to be hotbeds for bacteria and viruses. Some of these are hospitals and nursing homes, bottling plants, and central kitchens. Thanks to the molecular reactivity of ozone and its ability to quickly bond with other molecules, ozone spray is a powerful and safe disinfectant. Ozone oxidizing particles will neutralize biological matter, such as bacteria or viruses. This makes it an effective disinfectant, and incredibly potent when it is infused in water. 

Ozone spray does not affect the pH levels of target surfaces and doesn’t create any chemical byproducts after use. This means that it leaves behind no odors or abnormal tastes after treatment. In contrast, 75% alcohol sprays will leave behind some residue, and in the case of medical equipment used in the healthcare industry, alcohol sprays leave a pungent odor or taste, damages plastic and leather, and also causes dry skin.

Ozone as a Hand Sanitizer

When it comes to ozone spray and alcohol sprays for use as hand sanitizers, one study involving 30 participants found that ozone spray was more effective than alcohol spray for neutralizing the E. Coli bacteria. Furthermore, 20 percent of the participants reported adverse skin effects from the alcohol-based sanitizer, while no participants reported negative effects from the ozone spray. 

In considering whether to use a 70-80% alcohol spray or an ozone spray, ozone has the advantage of being able to act on free radicals or bacterial agents while it is in the air, whereas alcohol-based disinfectant sprays do not. They must be sprayed onto a surface and wiped across it to work effectively on harmful bacteria and other microorganisms. On the other hand, ozone, as natural gas, will begin neutralizing these substances whether they are airborne or settled onto a surface. 

With shortages of crucial medical resources and protective gear during the COVID-19 pandemic, many people have been looking for alternative disinfectant methods. Targeted studies have recently confirmed that ozone spray is effective in neutralizing the COVID-19 virus on surface areas. This is due to the way ozone immediately seeks to interact with bacteria and viruses on a molecular level once it comes into contact with them. 

Researchers in Japan have recently discovered that ozonated water can kill COVID-19. The revolutionary Space Sanitizer System from BES can be placed in a home or in a public area to sanitize a space. It releases ozone into the air as a mist and it works by using patented electrolysis technology to convert water into high purity ozone gas that is safely mixed and misted into the environment. It’s safe to use when people are in the room. This can eliminate bacteria and viruses in the air and on nearby surfaces without leaving harmful chemical residues.

Practical Benefits of Ozone Spray 

Ozone spray bottles such and particularly the Mobile Ozone Spray (MOS) from Biolux is the most advanced ozone spray on the market. This is due to its ability to produce a higher concentration of ozone and its remarkable ease of use. Just fill it with tap water and push the charge button, and it works in minutes.

Since disinfecting with ozone only requires the ozonation device and water, this means there is no need to purchase or store large amounts of harmful chemicals or special containers in a particular environment. On top of this, alcohol spray stored in large amounts poses a flammability risk. This is an important factor to consider relative to any potential fire hazards in a target environment. 

Additionally, using an ozone spray bottle like the MOB greatly reduces the time of the sanitization process. Since you are disinfecting with water and won’t be leaving any harmful residue behind, you are effectively combining the wash and rinse phases of the cleaning process. Once sprayed onto the target surface, after wiping down the surface the ozone will return back to oxygen, leaving the area free of harmful microorganisms and chemical residue.

Lastly, ozone spray can save costs over the long term. When using ozone spray as a disinfectant, there is no need to use excess water to cut chemicals, activate disinfectant properties, or go through an extra rinse phase. Ultimately, using ozone will cut down on water consumption for many businesses. Ozone also can kill bacteria at much lower temperatures than disinfectant methods which require water heated to higher temperatures. This will also help businesses to reduce regular energy consumption. 

As ozone technology becomes more affordable, using ozone spray as a disinfectant is becoming a desirable option for many. Those looking for a convenient and sustainable way of disinfecting surfaces in their home or business should consider ozone spray as a new, more sustainable standard.

Ozonated water is automatic and works with any ice maker. It’s easy to obtain now with the availability of commercial ozone generators (link to product). The Ice Machine Disinfection System by BioSure uses patented electrolytic technology to generate ozone-dissolved water with adjustable ozone levels. In other applications it can also be integrated with the existing water supply, transforming pure water into high-concentration antibacterial disinfection water. 

The system utilizes BioSure patented technology to produce ozone, the strongest food grade disinfectant approved by the FDA. When integrated with an ice machine under clean and extra clean settings, the ice harvest is disinfected and free of microorganisms. This way allows the ice produced to be ready for consumption and use in high-quality products, as well as for the storage of food products to maintain high levels of hygiene and prolong freshness.

Ozone – More Than Just Safe

There are several benefits for ice manufacturers and food and beverage businesses such as restaurants, catering services, central kitchens, and hotels to utilize Ozone Ice Machine Disinfection Systems from BioSure to secure edible ice sanitation. 

  1. Cost-saving
    Ozone ice reduces costs associated with cleaning crews that use chemical solutions to keep commercial ice machines sanitized.
  1. Less risk
    Even after thorough training, people sometimes still make mistakes in the mixing of chemicals and cleaning processes. Also cleaning crews could potentially damage ice machines from regularly cleaning them by hand. Ozone eliminates these risks in one fell swoop.
  1. More environmentally friendly
    Ozone will revert back to oxygen and produce no harmful substances after the reaction. It leaves no chemical residues, and it has no taste or smell after the reaction. It also has no effect on the pH balance of water. And rest assured, it causes no negative effect or irritation to our mouth, nose, or skin. The producing process creates no known carcinogen, allowing it to be discharged directly without causing environmental pollution.
  1. Reliability
    When considering the alternative, ozone is invaluable to businesses that serve cold beverages, whether it’s cafes, restaurants, or bars. These establishments have a responsibility to keep their customers safe. With ozone, both business owners and customers have peace of mind when enjoying a cold drink on a hot summer day.

Aside from ice machines, ozone is used in a number of applications and industries, including medical, dental, and food sanitation industries among others.

How Dirty is Restaurant Ice?最先出現在百特集團 | 中文官方網站。

]]>
Would you be willing to drink water taken from a toilet bowl? If you ask anyone, the answer is likely to be no. But did you know that the ice that goes in our beverage at bars and restaurants could possibly contain the same or even higher levels of bacteria than water taken from the toilet?

This is not merely alarmist. As several global news stories have shown us, there are cases of edible ice contamination happening all around the world, and more often than we thought.

Ice Contaminations Cases Around the World

In the US in 2013, an outbreak of norovirus caused by dirty ice at a golf course in Phoenix sickened 80 people. In 2018, a reporter who looked at restaurant report cards in North Carolina every week saw “dirty ice machines” often cited in the public reports.

Meanwhile, in China in 2013, ice cubes at fast-food chains were found to be riddled with 13 times more bacteria than toilet water. And in Hong Kong in 2017, edible ice samples collected under the routine Food Surveillance Programme of the Centre for Food Safety (CFS) were found to contain excessive coliform bacteria, organisms that are present in the environment and in the feces of all warm-blooded animals and humans. 

You may think European countries probably apply striker regulations and prevention toward food safety. However, studies done in Europe have shown dirty ice cases as well. In 2017, an undercover study by the BBC investigated iced beverages in the U.K. and found that out of 30 samples taken from three different fast-food restaurants, more than half were contaminated with fecal coliform bacteria. In 2013, a newspaper did an experiment that collected ice from ten well-known fast-food chains and announced that in six out of ten locations, those ice cubes “contained higher levels of bacteria than the water samples taken from toilet bowls at the same establishments”. 

How To Ensure The Safety of Edible Ice

Most people don’t give a second thought when they use ice. But those real-life cases above reveal the potential harms of dirty ice to our health and even to the public health system. It’s a little-known fact that ice machines that produce the ice we drink could potentially be a home for all manner of harmful bacteria, viruses, mold, and other microorganisms.

Ice should always be manufactured and handled with the same strict standards that we use to treat the rest of our food. Since more and more research has shown the importance of edible ice safety following numerous cases of edible ice contamination happening in the world, governments have made regulations for ice manufacturing and handling to make sure that edible ice must be produced, stored, and transported in clean and sanitary conditions. Ice manufacturers and food and beverage businesses such as restaurants, hotels, and bars, must monitor the cleanliness and hygiene of employees, use properly cleaned and maintained equipment, and use water that is safe and sanitary.

In addition to the above precautions, ozone is a powerful solution to help prevent bacteria from getting into ice that you or your customers consume.

The Magic of Ozone 

Ozonated water, which is usually produced by electrolytic ozone generators (E.O.G), is one of the strongest disinfectants known to mankind. It is an effective and fast disinfectant. Compared to general chlorine-based disinfectants, ozone disinfection speed is 3,000 times faster and 50 times stronger. Ozone water is also one of the safest disinfectants. It’s 100 percent natural, which makes it perfectly safe for human beings as well as for the environment in the right amounts. 

When it comes to ice and drinking water, the CDC has proclaimed that ozone is a safe and effective sanitation method, protecting against even some of the most resistant microorganisms.

Electrolytic ozone treatment works by combining electricity with water through an electrolytic ozone generator (E.O.G). It’s considered a safe and effective disinfectant alternative to chemicals for food safety applications. Including decontamination of water and sanitization of kitchen equipment, ozone is also very effective in eliminating biological matter in the water like bacteria or viruses, killing them instantly. 

After filtration, the water goes through electrolysis and the chemical ionization is finished. This helps remove any particulate matter that was created in the process. The final water supply is then completely free of impurities.?

Ozonated water has become an invaluable tool for a number of businesses. With any emerging technology, there are always concerns about safety and potential harm to humans. Ozone has proven to be a powerful disinfection technology used for over a hundred years to keep us safe from infections from bacteria and viruses. Those with concerns that ozone is harmful to humans can keep reading to learn about the many benefits of ozone across a number of industries, particularly compared to the use of chemical disinfection agents.

Ozonated water is one of the most effective sanitation solutions on the market. Recent advancements in electrolytic ozone technology have made ozone even more accessible by allowing the generating of ozonated water at higher concentrations with smaller machines that can fit in compact spaces. Ozone technology is used across a variety of industries, with applications for healthcare, food safety and sanitation, beverage, dentistry, professional laundry, and professional cleaning. 

For example, ozonated water can kill bacteria on surfaces of kitchen counters and food prep stations. It’s commonly used to disinfect fish, meat, vegetables, and poultry by removing bacteria and pathogens through a wash with ozonated water. It’s also effective at removing odors from mildew in washing machines and disinfecting dental water units.

Ozone leaves no chemical residue

Thanks to the ozone’s short half-life of an average of 15 minutes, it dissipates into oxygen after disinfection. This means if you were to disinfect a room with ozone mist, after twenty minutes there wouldn’t be any trace of ozone left, unlike chlorine. This is because ozone is unstable and reverts back to oxygen (O2). Research by the world recognized laboratory Campden BRI backs up these claims. Trials undertaken in 2014 found that ozone at the right concentrations and contact times can be an effective environmental disinfectant and when used correctly, causes no adverse effects after disinfection.

How ozone disinfects

We might be familiar with ozone in our atmosphere. But ozone can be generated on-demand as well. Ozone is highly reactive and attracts electrons from other compounds. It oxidizes — a process where it undergoes a reaction in which electrons are lost — drastically reducing the biological integrity of anything it attacks. Ozone ruptures the cellular walls of bacteria causing the cells to break down and so there’s no chance for the biological organism to build up immunity, unlike chemical disinfectants. Ozone can oxidize certain minerals as well, removing manganese and iron out of drinking water.

It disinfects surfaces

Ozonated water has been a blessing for the food and beverage and healthcare industries. In central kitchens and restaurant food prep stations, bacteria collect on surfaces that are used to prepare food. Some hotel chains and large restaurants require multiple food prep stations to handle a large number of customers. This makes it a challenge for kitchen staff to use chlorine to disinfect these food prep surfaces every night. For one, the storage of enough chlorine to disinfect every food prep station on a daily basis uses valuable facility space. Secondly, mixing the chlorine disinfection solution is prone to human error, especially if employees do not undergo proper training. With ozone, kitchen staff can simply spray ozonated water via an ozone spray bottle on surfaces, and rid them of bacteria by simply wiping them down, saving time, money, and hassle.

Is Ozone harmful for humans?

Ozonated water made through electrolytic ozone generators is safe for humans. The US and Europe have strict indoor ozone safety standards. If exposure is controlled, there are no safety issues. However, ozonated gas generated through the corona discharge methods does bring safety concerns. When inhaled, ozone gas can damage lungs, and relatively low amounts can cause chest pain, coughing, shortness of breath, and throat irritation. Ozone may also have negative effects on people with respiratory conditions such as asthma and affect their ability to fight respiratory infections.

Compared to the long term effects of using chlorine for disinfection, ozone is safer. Chlorine is a chemical disinfection agent that has drawbacks for both humans and the environment. Long-term exposure to low levels of chlorine gas is potentially linked to lung disease, including bronchitis, shortness of breath, possibly permanent damage, as well as tooth corrosion. Chlorine is also a comparatively weaker disinfection agent, offering relatively low protection against protozoa. On top of this, chlorine has lower disinfection effectiveness in turbid water, leaves a bad taste and odor, and is subject to human error when mixing the solution. This can lead to dangerous outcomes and often leads to using unsafe amounts. 

Ozone is your friend

Ozone is not to be feared. There is a myriad of benefits from ozonated water technology. While there are guidelines to follow for the safe and proper use of ozone, the benefits of ozonated water and electrolytic ozone technology far outweigh these concerns. Business owners are realizing this and are starting to replace chemical disinfection processes with ozone water at record numbers, due to both the overwhelming effectiveness and its benefits for the environment.

BES Group is one of the leading ozonated water manufactures. With numerous patents for revolutionary electrolytic ozone technology, BES Group ozone generators produce higher concentrations of ozonated water through compact devices that can be installed almost anywhere. With recent reports that ozonated water can kill Covid-19, ozone is now making a comeback in helping keep people safe from infection. Ozonated water is particularly important in businesses that fall into high-risk categories for Covid-19 infection, such as nursing homes, hospitals, and bars. Click here to learn more.

Water keeps us alive but it can also be home to harmful microbes, bacteria, and viruses. While most of us have access to treated water, this water can still be contaminated.

In recent years, there have been numerous disasters that contributed to people consuming unsafe water. A storm in Australia caused contaminated water in Melbourne. The storm brought down trees onto power lines, causing power outages. The power cuts lead to untreated water from Silvan Dam flowing freely into the water supply system. In the United States, California bushfire fires have contaminated the water with toxic substances, ash, and debris, making the water unsafe to drink. The Flint water crisis in Michigan has exposed hundreds and thousands of residents to elevated lead levels, and it’s still not resolved after the contamination started in 2014.

How Can We Ensure Our Safety? 

Kate, a high-end California restaurant owner, found herself in hot water after the biofilm was found in a water line, contaminating the drinking water. Despite rigid hygiene measures and extensive staff training, her restaurant still received complaints from customers who came down with food poisoning. It’s caused her to lose money by refunds and compensation, and the bad online reviews are permanent. In salvaging her restaurant, she looked into several sanitation methods for a cost-effective sanitation process that can ensure the drinking water is safe to serve.

Chemical-free Sanitation Methods

There are several sanitation processes for restaurants and central kitchens. Each can achieve different levels of disinfection. Ozonation and UV Irradiation are two widely used disinfection methods with applications in food and beverage, healthcare, water line disinfection, and other industries. Both methods are chemical-free. 

What is Ozone Sanitation?

Ozone is a highly reactive oxidizer that oxidizes almost everything from inorganic compounds to bacteria. Ozonation uses ozone to diminish infection and viruses and bacteria. Due to its highly reactive properties, the ozone used reverts back to oxygen immediately after disinfection, leaving it safe and with no residual ozone or other compounds. When ozonation is used to disinfect water, it doesn’t create a bad “aftertaste” as chlorine does. On the contrary, it is widely used specifically for its odor removal properties.

Ozonated water has come on top as a more effective sanitation method compared to UV irradiation. A study from the National Key Research and Development Program of China showed that the toxin degradation rate of ozone was higher than UV irradiation by more than 11 percent. This is because, during ozonation, inorganic and organic compounds are both oxidized. This means that ozone can reduce the toxicity of pesticides to produce better than UV irradiation.

Electrolytic ozone is one of the best ways to create ozone because it generates ozone with less energy. This is a method whereby tap water is charged with electricity to infuse it with ozone at up to 28% ppm, a high enough concentration to make it lethal against bacteria and viruses, but safe for humans to use. Using this cutting-edge technology, electrolytic ozone can be affordable, stable, and easy to manage. The newest ozone creation technologies produce high-purity reactive ozone without polluting the environment with the byproduct of nitrogen oxide. 

Ultra Violet (UV) light is a form of electromagnetic radiation. There are three types of UV light. UV-A and UV-B are the types of radiation that pass through the atmosphere and hit up our beaches, which give some of us a lovely tan while giving others a painful sunburn. Luckily, the atmosphere absorbs most of the third type – UV-C, the highest-energy and most dangerous of the three. Employing UV irradiation is a well-known sanitation method. It kills germs by hitting them with the most energetic type of UV light, UV-C.

Ozonated Water vs UV Light Sanitation

Conssome traditional ozonated water generators may require technical know-how to install and are less economicalstrict condition needed risks of skin cancer if exposed directly slow process costly early performance deterioration 

The Best Chemical-Free Sanitation Method

Weighing up all the pros and cons, it is clear that ozonation is a more effective disinfection option than UV irradiation, thanks to its permeability, efficacy, and practicality. UV irradiation is highly effective under the right conditions, but ozonated water has a high reactivity that results in speedy sanitation without producing any byproducts. Meanwhile, UV irradiation requires microbes to be exposed to intense light for an extended period of time.

BioSure manufactures a compact, easy-to-use, and effective ozone disinfection system. The BioSure Post-Filtration Disinfection System is one of the best systems on the market. This system uses patented electrolytic ozone to provide instant and residual-free sanitation with simple installation. This easy-to-use system can keep beverage makers, water coolers, or dental unit waterlines clean and safe.

The BES Ozonated Water System or OWS Series doesn’t just provide an ozone cleaning and disinfecting system — it does so with greater purity, more consistent water flow, and higher levels of ozone. As ozone is an effective sanitizer that can be used even in cold water to effectively clean linen, nursing homes stand to significantly save on energy and electricity costs by reducing the use of hot water requirements for laundry.

The OWS Series can be installed in laundry water lines to implement ozonated water into every segment of the laundry process in nursing homes. It pumps ozonated water that sanitizes the tap water running through the pipes of the nursing home — water that is used to not only clean all aspects of the laundry requirements but the actual washing machines themselves.

The OWS Series sanitizes the physical pipelines, as well as all of the water that passes through them. What’s more, the process eliminates biofilm or residue in the pipelines that lead into the washing machines, meaning only pure, clean water is dispersed into the laundry machines. This greatly reduces the mildew and mold in laundry rooms and on linens.

Washing with ozonated water means using one of the most powerful disinfectants available, but it also allows for washing in lukewarm and cold water. On top of this, the bleaching properties of ozone can reduce the amount of laundry detergent and other chemicals used, which in turn decreases the chemical discharge and pollutants produced with each laundry load. It’s not only good for the environment, but it also reduces the number of chemicals that come into contact with clothing. This means clothing and linens last longer.

The Benefits of Ozone Instead for Laundry

Longer lasting clothing is a nice benefit, but for some people, great looking clothing might be even more important. While ozone cannot replace bleach as a laundry bleaching agent, it’s possible to use less bleach and other detergents because ozone is a better catalyst for bleach than hot water. It not only reduces the use of bleach but in addition it helps reduce detergents, degreasers, and fabric softeners. However, bleach is still required to whiten, although less may be required depending on existing conditions within a facility.

Ozonated water has enough benefits that more nursing homes are implementing ozone into their sanitizing procedures. With nursing home residents among the most vulnerable to the COVID-19 virus, the need to implement efficient and cost-effective sanitation systems is critical. 

The BES Ozonated Water System or OWS Series doesn’t just provide an ozonation cleaning and disinfecting system — it does so with greater purity, more consistent water flow, and higher levels of ozone.
