WATER TREATMENT
HOME / ARTICLES / WATER TREATMENT WHY TREAT WATER WITH UV-C? 05.06.2019 Treatment for drinking water is done to make sure the water meets the requirements for drinking water, improving organoleptic (color, smell, taste), chemical (e.g., removing iron and manganese) and microbiological characteristics (eliminating bacteria harmful to human health like E. coli, Giardia, Legionella, Salmonella, etc.). The quality of water depends on its origin. The highest quality waters are those derived from sources and deep wells; they generally require simple treatments (sedimentation, filtration, and disinfection) as they benefit from the natural phenomena of “self-purification” that occur during the filtration of water in the soil and the layers of the subsoil. Surface and some groundwater, especially lowland waters, require longer treatment chains because of their characteristics and vulnerability to accidental pollution. In some groundwater, it is necessary to carry out treatments to remove pollutants of both natural and anthropogenic origin. The disinfection process is the final treatment stage that acts on the residual microbiological component and ensures the absence of pathogenic microorganisms. In the treatment chain, disinfection is essential to ensure adequate hygienic-sanitary protection. Disinfection through UV-C rays with the help of UV-WATER allows the killing of the microbiological forms present in the water without altering the chemistry. This process will reduce the incidence of water purchase costs per family; with the application of our UV water, you can have water always ready to drink, and no more buying and transporting crates of water from the supermarket to your home. Regarding the ecological response of UV-WATER, in recent years, there have been many campaigns for the reduction of plastic; on 19 December 2018, the European Commission issued an agreement to cut the production of disposable plastic objects. Using UV-WATER has earned us many favors, respected the environment, and reduced consumption. We respect the environment around us and avoid using disposable bottles. BACK
UVGI TECHNOLOGY AT A GLANCE
HOME / ARTICLES / UVGI TECHNOLOGY AT A GLANCE UVGI TECHNOLOGY AT A GLANCE 03.29.2018 Ultraviolet rays are part of electromagnetic radiation bounded by the lower wavelength extreme of the visible spectrum and the upper end of the X-ray radiation band. The spectral range of ultraviolet radiation is between 100 and 400nm (1nm=10-9m) and is invisible to human eyes. The UV spectrum is subdivided into three bands: UV-A (long-wave) from 315 to 400 nm UV-B (medium-wave) from 280 to 315 nm UV-C (short-wave) from 100 to 280 nm The portion of the UV spectrum (the “disinfecting” region) that is relevant for disinfection is the range that is absorbed by DNA (RNA in some viruses). This “disinfecting range” is approximately 200 – 300 nm, with a peak of germicidal effectiveness at about 265 nm. Absorption of a UV photon by a DNA chain of a dangerous microorganism disrupts a link and, consequently, inhibits DNA replication. 265,0 nm peak of disinfectant effect 253,7 nm standard UV-C bulbs 280,0 nm LED wavelength (NEW!!) There are different types of lamp. The discharge lamp emits light by luminescence from an ionized gas. The ionization of the gas is obtained through a potential difference, which migrates free electrons and positive ions to the different ends of the lamp (where there are electrodes). Low-pressure UV lamps. These offer high efficiency (approximately 35% UV-C) but low power, typically 1 W/cm (energy per arc length unit). They produce ultraviolet radiation at 254 nm. UV amalgam lamps. A high-power version of low-pressure lamps. Their efficiency is slightly less than traditional low-pressure lamps (approximately 33% UV-C), and the power density is about 2-3 W/cm. They operate at high temperatures and have a lifetime of up to 16000 hours. Medium-pressure UV lamps. These lamps have a spectrum with a pronounced peak and high radiation production but a low efficiency of 15% or less for UV-C. They produce polychromatic light from 200 nm up to visible and infrared light. The typical power density is 30 W/cm³ or larger. Low-pressure and amalgam lamps emit light at 254 nm and 185 nm (by oxidation) depending on the quartz glass used for the lamp body. Light at 185 nm is used to produce ozone. All these UV-C sources are exhausted both by the “discharge” of the gas contained within the bulb and by the progressive loss of transparency of the glass that forms them, in which electrons are deposited. This is the typology. The UV-C lamps can be divided into: Common UVGI lamps High output (HO) Amalgam Medium pressure Ozone LED UV-C. LED NEW TECHNOLOGY The most innovative source of ultraviolet rays is UV-C LEDs. These microscopic UV light sources can achieve the same results as standard UV lamps while offering extreme portability, power, and applicability features. Due to their recent implementation, it is now possible to design novel products for the sanitization of water and surfaces. These products could not even be imagined until a few years ago. UV-C Light Emitting Diodes (LEDs). LEDs are optoelectronic devices that exploit the properties of semiconductor materials. They consist of three layers: The so-called N layer contains electrons. The player, with gaps (i.e., positive charge carriers). An intermediate layer (the active layer) consists of a semiconductor. Electrons combine with the holes by applying a voltage to the n and p layers and emit photons – i.e., LIGHT. Unlike traditional light sources, whose output wavelength is fixed, UV LEDs can be manufactured to operate at the optimum wavelength for the application. 265nm is widely recognized as the peak absorption of DNA; however, 275-280 nm is widely used for its excellent stability. UV LEDs also switch on and off instantly and can be pulsed without any detriment to their lifetime, making them more user-friendly and safer for the operator. The design rules for UV LEDs open new opportunities for what can be disinfected: we are no longer limited to a long tube but can mount the LEDs in flat panels; on flexible circuit boards; on the outside of cylinders; the options are almost endless UV-C LED: NO HEAT, WAVELENGTH SELECTION, INSTANT POWER, MERCURY FREE, DESIGN EXTREME FLEXIBILITY Vs UV-C lamp: LOW POWER, UNCERTAINTY IN TECHNICAL VALUES, PRICE, RELIABILITY, DESIGNED-PER-VOLUME.

UV IN PROFESSIONAL KITCHENS
HOME / ARTICLES / UV IN KITCHENS UV-C in Professional Kitchens – Grease Elimination and Odor Control 08.19.2022 Keeping the kitchen hood and exhaust system ducts clean and hygienic is crucial in restaurants, large kitchens, community kitchens, shopping malls, office buildings, hotels, and food courts. Proper hygiene prevents (and eliminates) devastating problems caused by inefficient ventilation systems while reducing the risk of fires. Besides this, the challenges associated with reducing the odors produced by cooking food are widespread and represent an increasing issue in all restaurants. FOUL ODORS PRODUCED BY COOKING FOOD The type and quantity of pollutants emitted depend mainly on the cooked product, the cooking methods, and the means used. The substances responsible for cooking odors are fatty acids, aliphatic and aromatic hydrocarbons, aromatic amines, and aldehydes. There are many ways to filter odors, but there are no specific rules for “olfactory pollution.”Odor is a complex phenomenon to understand, not just for the wide range of potentially odorous substances, but mainly because the ability of a sense to be perceived by our olfactory system depends on different aspects that are both objective (volatility, water solubility, etc.) and subjective (physiological and psychological of the observer) but can also involve the environment (temperature, pressure, relative humidity of the air, speed and direction of the winds). This means that the same substance, at a distance from the source, is perceived differently by different people.Organic compounds can constitute a vital friction point between the restaurant/hotel/catering and the surrounding environment since smells can spread over large areas. Without that, anybody can carry out resolutive interventions to contain it, avoiding the exasperation of the people involved. GREASE AND THE RISK OF FIRE According to the National Fire Protection Association (NFPA) in the USA, most restaurant fires originate on kitchen cooking appliances, flare into the kitchen exhaust system laden with grease, and then onto the building roof. Fat pollutants are also generated during food cooking, and grease layers will form inside the kitchen hood and the exhaust system ducts. So besides the inconveniences caused by unpleasant smells, fat deposits can pose a risk of fire risks. To prevent the formation of grease in the exhaust system ducts, continuous maintenance operations are necessary.UV-C LAMPS TO PREVENT THE RISK OF FIRE AND ANNOYING SMELLSUV-C lamps are unique lamps whose light emissions can break the bonds of fat compounds by “breaking” them down into simpler molecules already present in the air (such as H2O, CO2, etc.). This is scientifically called “cold combustion.”So UV-C technology is the most effective way to reduce grease deposition on the ductwork and pollution in the exhaust system ducts. The advantages of using this technology extend far beyond their effectiveness and, among other things, allow you to: REDUCE THE RISK OF FIRE REDUCE COSTS for the maintenance of the kitchen hood and the exhaust system ducts REDUCE THE USE OF CHEMICALS FOR SCIENCE ENSURING SAFETY in the cooking area ENSURING CLEANING and hygiene of the cooking area EFFECTIVENESS OF THE LIGHT PROGRESS “UV-SMELL” PRODUCT Suppose it is challenging to test the effectiveness of reducing odors since they are perceived differently from person to person. In that case, it is, however, possible to carry out tests to verify the effectiveness of UV-C technology in reducing the formation of grease inside kitchen hoods and smoke evacuation systems. Light Progress Srl designed and manufactured a “UV-SMELL” section in Italy as part of our study. We ran an internal test on 12 different UV-C applications in professional kitchens. The test shows that in each of the 12 applications, the grease concentration inside the hood is significantly reduced if a UV-C section is placed inside the hood. The “UV-SMELL” systems can be installed in hoods that treat from 1,000 mc / h up to 4,800 mc / h of exhausted air and are, therefore, a flexible solution for various systems, both newly installed and existing. COMBINE UV-C WITH OZONE, TITANIUM DIOXIDE, AND CARBON FILTERS FOR ADDITIONAL EFFICACY The ideal ventilation system in a large professional kitchen should include a portion containing UV-C lamps, possibly with lights with Ozone emissions and filtration systems in Titanium Dioxide (TiO2) and Silver Salts to achieve higher efficiency. The first combination is with TIOX® honeycomb filters, an original Light Progress filter coated with nano-structured Titanium Dioxide (TiO2) and Silver Salts that, in combination with the very high UV-C power emitted by lamps, is an excellent photo-catalyst that degrades pollutants and organic and inorganic compounds (SOV, NOx, and VOC volatile organic compounds, nitrogen oxides). Consequently, the TIOX® filter performs further oxidation of polluting particles and contributes significantly to the deodorizing action of UV-C. Installation is straightforward and safe; the only precaution is to mount it downstream of mechanical filters that micronize fat molecules like standard mesh or labyrinth filters. A second option for maintaining cleanliness and eliminating odors is to use UV-C lamps that emit ozone. An oxidation reaction is triggered as soon as ozone comes into contact with molecules, which are oxidized and transformed into harmless molecules, thus eliminating any form of foul smell. Some lamps can be made with special transparent quartz at a wavelength of 180 nanometers, which can “transform” oxygen molecules into Ozone (O3). The application in the kitchens’ ventilation channels effectively eliminates odors precisely because ozone can “follow” the smells along the ductwork, eliminating them before they are released outside. The properties of ozone are both ultra clean and persistent over time; ozone is, in fact, a volatile molecule that tends to re-transform into oxygen soon. Finally, applying UV-C technology, stand-alone or combined with Ozone emissions and Titanium Dioxide filters, perfectly combines with activated carbon filters. These technologies fight odors effectively together, and carbon filters are vastly improved by applying ultraviolet rays, increasing their durability and efficiency. A SAFE TECHNOLOGY, SUITABLE FOR NEW APPLICATIONS AND RETROFIT APPLICATIONS Installation of the technologies mentioned above is widespread in professional kitchens. Despite certain best practices and recommendations, their technologies are safe and easy to install. Installing UV systems right after the hood keeps surfaces
SICK BUILDING SYNDROME
HOME / ARTICLES / SICK BUILDING SYNDROME SICK BUILDING SYNDROME and WELL BUILDING STANDARD 09.07.2018 What is Sick Building Syndrome? Sick building syndrome (SBS) is a condition that results in headaches and respiratory problems and is attributed to unhealthy or stressful factors in the workplace, such as poor ventilation. The case study reveals that many disorders afflict individuals who spend many hours indoors. In recent decades this habit has taken root with the consequence that, while on the one hand, the need to have protected environments with acceptable microclimate standards has grown, on the other hand, the demand to contain energy consumption by eliminating waste and sealing workplaces has increased. The sick building syndrome, as found by the O.M.S. itself, manifests through a combination of symptoms related to staying in the building. These include irritation of the skin and mucous membranes, headaches, mental fatigue, and difficulty concentrating. A characteristic of Sick Building Syndrome (S.B.S.) is that most symptoms disappear or fade away from the “sick building.” The buildings, then, become containers where air quality is contaminated by countless factors that affect the health of the people who live there. Scholars suggest the most effective approach for a cure for Alzheimer’s disease is bio-psycho-architectural, which focuses on environmental control, conscious design, which puts design and planning at the service of those who will live in the building. The Well Building Standard is a certification that helps to prevent these problems. It is the first health and wellness standard to promote wellbeing through the design and construction of buildings. These standards measure the attributes of buildings that impact occupants’ health by examining seven factors or concepts: AIR WATER NOISE LIGHT FITNESS COMFORT MIND With this approach based on medical research, we explore the connection between buildings where we spend more than 90% of our time and the impacts on the health and well-being of us as occupants. It is no coincidence that air is the first of the seven concepts on which the Well standard is based and that the designer of the building must take into account the fact that to optimize and achieve high standards of indoor air quality, one must consider three aspects: remove contaminants, prevent their appearance and manage purification. The WELL standard proposes using UV-C technology to reduce the microbial load in the air, which would lead to an increase in IAQ. BACK
REDUCING COVID IN DENTAL OFFICES
HOME / ARTICLES / REDUCING COVID IN DENTAL OFFICES UV-C in Healthcare: Reducing the risk of Covid-19 infection in Dental Offices 05.05.2022 Throughout the world, the global crisis caused by the spread of SARS-CoV-2 Coronavirus has brought all dental activities outside the emergency sector to a standstill. It is now a question of drawing up and implementing protocols that protect doctors and medical staff and prevent cross-contamination and consequent infection of patients once they are allowed to reopen practices. We do not think it is helpful to focus here on the general and consensual measures in the waiting room (social distancing, limiting the number of patients, wearing masks, avoiding shaking hands…) and to protect the staff (frequent hand washing/disinfection, FFP2/FFP3 masks and face protection during clinical procedures…). Instead, we would like to highlight two points that are rarely mentioned in the protocols currently in circulation. The most straightforward way to significantly reduce the risk of cross-contamination, as taught in all good dental schools, is to increase the average time of treatment: if this average time is doubled, the risk of cross-contamination of patients and dental staff is halved. At the same time, the negative financial impact of time-consuming cleaning/disinfection procedures is halved. The second point concerns dental aerosols. On the one hand, SARS-CoV-2 is a respiratory virus that is very different from the viruses we are used to dealing with, such as HIV, hepatitis B, and C. This means the virus does not need to enter a wound for cross-contamination; simple airborne transmission is possible, as with viruses that cause colds (rhinopharyngitis) or the flu. But with potentially much more severe consequences.For the German Hospital Hygiene Association, coughing, singing, or simply talking are the primary sources of virus spread. This suspicion is confirmed by a letter from the American National Academy of Science to the White House. This letter suggests that Coronavirus could remain in the mist formed during breathing. Furthermore, soil contaminated by patients in Chinese hospitals could be the source of new aerosols due to cleaning or staff relocation. An article in the New England Journal of Medicine (March 2020) found that the virus was viable for several hours in experimental aerosols. The same paper describes the survival of the virus for up to 3 days on metal surfaces like metal or plastic. Since a high proportion of patients who are positive for SARS-CoV-2 will be symptom-free or with very mild effects, symptomatic patients are infectious a few days before the onset of symptoms and possibly long enough after symptoms have subsided, all patients should be considered potentially infectious. For this reason, the use of masks in the waiting room is recommended for patients and secretarial staff. Once dental treatment begins, the mask is removed, and the patient may become the source of a cloud of microdroplets. In addition, dentistry is characterized by the generation of very powerful aerosols through ultrasonic scalers, air/water spraying, air/water cooled, or air/water-cooled rotary instruments. The resulting cloud of microdroplets is contaminated with microflora from the patient’s mouth and upper airways. This is an extraordinary situation: Not only does the patient not wear a mask and has a wide open mouth, but his oropharyngeal microflora is strongly scattered outwards by some dental treatments. It has been shown (Micik et al., 1969; Graetz C et al., 2014) that dental aerosols produce splashes with particles > 50 µm, which exhibit behavior that can be described as “ballistic” and directly contaminate the surfaces facing the patient (equipment carrier, floor) over a distance of 0.5 to 2 meters. However, dental aerosols also produce a cloud of micro-droplets < 1 µm, which remain suspended in the air and may penetrate directly into the lungs. This microdroplet cloud is highly contaminated with oropharyngeal microflora (Dutil et al., 2009; Hallier et al., 2010; Kobza et al., 2018), and recent studies have shown that SARS-CoV-2 can remain viable for up to 3 hours in comparable aerosols (van Doremalen et al., 2020). Recent work on these microdroplet clouds shows that they remain suspended for long periods and can spread over long distances. For dental practices, this means that after generating an aerosol in a Coronavirus-positive patient (often not symptomatic, see above), the ambient air can be potentially infectious for staff and the next patient. This micro-droplet cloud will gradually settle on all surfaces in the dental office, including the floor. To reduce the risk of cross-contamination, significant measures should therefore be taken to decontaminate the atmosphere and all surfaces before treating the next patient such as reducing the risk of cross-contamination by aerosols and reducing aerosol formation/contamination during treatment. Aerosols are only produced during treatments with ultrasonic scalers, air/water spraying, or air/water-cooled rotating instruments. For example, manual scaling/root gouging, tooth extraction, and implant placement are less at risk. It has been shown (Kampf et al., 2020) that hydrogen peroxide (H2O2) at 0.5% for 1 minute effectively kills the virus, as does povidone-iodine. A mouth rinse with 1% H2O2 or betadine can therefore be recommended before dental work begins. Note that chlorhexidine has a negligible or no effect on Coronavirus! High performance vacuuming during aerosol generation processes can significantly reduce (up to 90%) the power of aerosols but not eliminate them. Caution: Check where the aspirated air is discharged (see below). The use of a rubber dam, when clinically indicated, can increase the strength of the aerosol but reduce microbial contamination. Reduction of air pollution. There are various methods of continuous air disinfection/cleaning: Ventilation systems with HEPA filters effectively reduce the virucidal load in the air (SARS-CoV-2 has a size of 0.1 µm, but since micro-droplets carry it, it is effectively stopped by HEPA filters with a pore diameter of 0.3 µm). However, the filters themselves can be highly infectious. Ventilation systems that combine filters (ideally HEPA filters) with UV disinfection of the filtered air appear to be most effective at decontaminating the atmosphere. Several articles (see below) have shown that UV in sufficient doses effectively destroys the RNA of viruses, including
Healthy and Clean Air
HOME / ARTICLES / HEALTHY AND CLEAN AIR Healthy and Clean Air – Our motto for more than 30 years! 12.10.2019 Air disinfection in community structures (schools, hospitals, offices) is essential because it avoids the diffusion of viruses and microbes that often cause more or less severe infections. With UV-C devices, you can disinfect the air, and keep the components of your air conditioning system clean and efficient without the use of chemicals, while keeping the consumption of energy and water under control. The keys to continued HVAC performance are cleaning cooling coils, drainage trays, and other “wet” components. A building without UV-C products would have all the elements defined as “wet” coated with biofilm and organic compounds-these products, resulting from poor cleaning, escape through the air ducts. When mold, biofilm, and other organic compounds accumulate. The air inside the ducts deteriorates in terms of quality. Odors develop, and respiratory irritants, pathogens, and allergens spread. The flow of air through the batteries becomes limited due to fouling, which impacts comfort and energy performance. Equipment and material life are reduced, and maintenance requirements are increasing, which entails a threat to the “three E’s” of a building: Energy, Efficiency, and Economics… all of which contribute to achieving a green building. By reducing energy and water consumption, ultraviolet (UV-C) lighting maintains the cleanliness of HVAC components and minimizes the use of chemicals. UV-C helps maintain or retrofit IAQ significantly. According to ASHRAE and the U.S. General Services Administration, UV-C rays prevent microbial “growth and transfer” in living spaces. The application of UV prevents the formation and reduces the spread of different categories of organisms, which can grow and spread in modern air treatment systems. These include pathogens (viruses, bacteria, and fungi, which can cause a variety of diseases), allergens (bacteria and molds, which can cause allergic rhinitis, asthma, humidifier fever, and hypersensitivity pneumonia), and toxins (endotoxins and mycotoxins, which can cause a variety of toxic effects, irritation, and odors).

Healthcare Associated Infections
HOME / ARTICLES / HEALTHCARE ASSOCIATED INFECTIONS Healthcare Associated Infections: An Avoidable Risk 11.12.2018 HAIs (Healthcare Associated Infections) are diseases that affect patients inside hospitals and are not present or incubating at the time of admission. In addition to patients, hospital employees are frequently infected with HAIs after discharge. No one should get sick while seeking care! Yet, globally, hundreds of millions of people are affected annually by healthcare-associated infections (HAIs), many of which are completely avoidable, and antibiotic-resistant organisms cause a large proportion. No country or health system, even the most developed or sophisticated, can claim to be free of HAIs. One out of every 25 admissions contracts HAI. Some of the consequences are: Increasing mortality and increasing costs 30% of ICU patients are affected by at least one episode of healthcare-associated infection. Newborns are also at higher risk, especially in low-income areas. Among hospital-born babies in developing countries, HAIs are responsible for 4% to 56% of all causes of death in the neonatal period. Prevention, prevention, prevention. No solution will, by itself, solve the problem. However, protocols and best practices have been established by the CDC, the World Health Organization, and many others. In every hospital and clinic, sterilization, disinfection, and cleaning are the three pillars of prevention. Effective infection prevention and control reduce healthcare-associated infections by at least 30%. Although significant progress has been made in preventing some types of HAIs, much more work is needed. UltraViolet Technology is an excellent opportunity to exploit UV–C lights to penetrate inside bacteria, spores, fungi, molds, mites, and viruses. UV–C high energy is absorbed at RNA and DNA levels, damaging nucleic acids and inhibiting cellular growth & proliferation. UV–C‘s action is effective within seconds of irradiation. Any surface, water, or air can be disinfected at 99,9% using UV-C. UVGI is a science-proven technology. UVGI technology is a physical disinfection method with a significant cost/benefits ratio; it’s ecological, and, unlike chemicals, it eliminates every microorganism, including multidrug-resistant (MDR) pathogens. Research is still ongoing, but there is much evidence on the efficacy of UVGI and the proper way to use it, though its application has yet to fully mature. How could we apply UV technology to prevent HAIs in medical environments? What is one of the most contaminated surfaces inside any hospital? Hands. For this reason, there are so many campaigns to educate people to wash their hands…clean hands can save lives! So, what is comparable to hands? What is the most commonly used tool in any hospital? Stethoscope contamination The stethoscope is the most widely used instrument in any medical environment. It is used in rich countries, developing countries, private clinics, and field hospitals. It is used by doctors, nurses, and other health professionals. Stethoscopes carry several different pathogens, and they are usually never clean. Doctors are primarily focused on diagnosing and treating patients. There is often a rush between appointments. Standard cleaning includes the use of disposable chemicals and the creation of special wastes. How could we apply UV technology to STETHOSCOPES? The most innovative source of ultraviolet rays is UV-C LEDs. These microscopic UV light sources can achieve the same results as standard UV lamps while offering extreme portability, power, and applicability features. Since their recent implementation, it has been possible to design cutting-edge products for the sanitation of water and surfaces that could not even be imagined until a few years ago. STET CLEAN is a “Wearable Disinfection” Portable Version: designed to follow your stethoscope everywhere you travel. Its features include the following: Double control system – optical sensor and mechanical – for use in operational safety conditions Microprocessor for irradiation and security controls Special polycarbonate body Lightweight (100 grams) and pocket-sized (limited footprint), like a typical smartphone Special shiny polycarbonate body Compatible with every stethoscope type and dimension (pediatric, neonatal, cardiological…) It fits the most common stethoscope size (around 46 / 47 cm diameter, i.e., Littman Classic II).

FOOD TREATMENT
HOME / ARTICLES / FOOD TREATMENT INCREASE FOOD QUALITY WITH UV-C TREATMENT 07.31.2019 We’ve all heard: “You’re what you eat,” a thought that is increasingly relevant and common in this historical period in which consumers are increasingly attentive to the choice of product and the supply chain that accompanies it before arriving in the aisles of the supermarket and on our tables. UV-C rays have been part of food production for over 50 years. It has been proven that UV-C treatment eliminates E. coli, Salmonella, Listeria, and other foodborne pathogens and is a safe and proven way to prolong the shelf life of food and drink. This means that large manufacturing companies intervene in terms of safety and control to ensure quality and peace of mind for the final consumer. The vast majority of the products displayed on the counter are withdrawn due to loss of freshness or even deterioration of the product. This is caused by microorganisms such as bacteria, fungi, molds, and their spores, which propagate through the air and circulate inside the counter, causing cross-contamination between foods. In terms of applications, UV-C devices can be installed inside food banks to protect against contamination. Upstream, careful management of the conservation and quality process occurs in the production phase. Analyzing a production line, we can identify several points where a disinfecting UV-C source is crucial. Surface treatment of the product eliminates any contaminated surface agents. By transporting microorganisms, treating them, and allowing them to be purified of these elements, the air ensures continued protection and prevents premature deterioration. Treatments used during the packaging phase can include the disinfection of packaging films, conveyor belts, bottling lines, and carousels for the disinfection of bottles and their closure capsules. In addition, the same food products must be decontaminated, including the surfaces of belts, products, packages, etc. UV-C is a proven method to improve safety and prolong the shelf life of many food products. This technology does not pose a risk to food and beverage safety. BACK
