Disinfection UV LED Application

Disinfection UV LED Application

Did you know that you could use UV LED to kill or inactivate harmful pathogens such as Coronavirus and prevent the spread of waterborne and airborne diseases? Surprisingly, scientists have been doing this since the 1800s, but the practice has gained popularity more recently due to the emergence and scourge of the 2019 pandemic. 

This article gives an overview of the application of disinfection UV LED, its evolution, and its potential in transforming water, air, and surface treatment in homes and various facilities. 

The Use of Large Scale UV LED Water Disinfection 

The first experiment of water disinfection using UV LED was done in France in 1910. However, chlorine outpaced disinfection UV LED until 1955, when large scale UV systems were operationalized in Australia and Switzerland. 

In the decades that followed, UV was used increasingly due to concerns over the carcinogenic disinfection byproducts from the use of chlorine. The use of disinfection UV LED gathered more pace when scientists discovered that UV light could effectively kill bacteria and viruses and prevent the spread of Giardia and Cryptosporidium that were highly resistant to chlorine treatment.  

Since then, disinfection UV LED has always been used as a second barrier to wastewater treatment around the globe. 

Small Scale Application of Disinfection UV LED

UV light-emitting diode (LED) is developed through several iterations of material and manufacturing improvements. This technology offers significant improvement and opportunities in many manufacturing processes. 

The technology has reduced maintenance costs and increased manufacturing speeds. For these reasons, its application has improved dramatically over many areas such as the food, medical and manufacturing industries. 

Disinfection of Laboratory and Equipment surfaces

Disinfection UV LED technology offers you reliable and rapid disinfection of surfaces and equipment bot at home and working environment. The healthcare sector has particularly benefited from UV LED disinfection due to the continuing problem of Clostridium difficile spore transmission from surface to surface. 

A recent study shows that the transmission of the Clostridium difficile spore can be stopped with high-intensity UV LEDs by5.79 log 10 I seconds. 

The spread of the Clostridium difficile spore on the surface can be stopped in less than 30 seconds with a high-intensity UV LED with a combination of 275nm + 365nm and 275nm alone in a drive greater than 5.79 log.  

There is also synergism between 365nm and 275nm UV LED when inactivating RNase A irreversibly. The new approach to irreversible spore inactivation involves targeting functional groups and protein stabilization. Thus, disinfection UV LED inactivates microorganisms and assures you that the surfaces are disinfected even without the use of chemicals or countless rinses. 

Disinfection of Packaging Materials 

Many industries today, especially in the food and beverage, pharmaceutical and medical and as well as cosmetic and manufacturing operations. Packaging materials in these industries can be disinfected using various methods such as heat and chemical processing. 

These methods, however, are quite expensive and time-consuming. Disinfection UV LED is an ideal alternative to these traditional methods because it does not require much effort to execute. It also has a long lifespan, and it is dry hence does not require drying up after disinfection like liquid disinfection substances. 

High-intensity UV LED disinfection technology presents you with unmatched levels of deep UV irradiance, which enables significant improvements in analysis and operations as well as increased capabilities for disinfection 

and decontamination application which requires low wavelengths. 

UV LED technology also enables complete inactivation of contaminants within minutes, which is way faster than traditional methods. If you are in the manufacturing industry, you could use the new, improved disinfection UV LEDs with higher throughput, quality and yield. 

This technology also provides enhanced capabilities for food, pharmaceutical, and food disinfection and decontamination applications. Disinfection UV LED also optimizes the disinfection process and bring new packaging capabilities to the market.  

Disinfection for Manufacturing

There are numerous sectors where disinfection and decontamination of surfaces in the manufacturing industry require serious considerations. These sectors include pharmaceutical, chemical and cosmetic manufacturing sectors.

Using high UV LED irradiances combined with appropriate wavelengths attacks specific bonds in the RNA, DNA and proteins of disease-causing biomolecules and microorganisms. This technology, therefore, reduces the amount of time it takes to inactivate pathogens and improve the overall efficiency of the disinfectant.

UV LED solutions with low irradiance have significantly limited the efficacy of UV LED solutions over the past few decades. The 275nm UV LED disinfection system is greater and more efficient than other technologies in the market. It produces a level of irradiance that provides manufacturers with the ability to move beyond traditional disinfection technologies.

This high performance, long-lasting UV LED solution provides customers with improved disinfection capabilities that lower the overall cost of production.   

Disinfection for Food and Beverage Safety

Disinfection UV LED technology has brought significant improvement in food and beverage processing applications. For example, disinfection of the conveyer belt using UV LED technology to inactivate microorganisms after food has passed through it reduces maintenance cost and increases manufacturing speed. 


Getting a system that can quickly turn on and off will enable you to have more productive and sterile operations. However, it is good to turn disinfection UV LEDs only when necessary to extend their lifespan. 

Bottom Line

UV LED manufacturing is improving at a dramatic speed. Its application has broadened from photochemistry and chemical stream monitoring to food disinfection for safety—recent research and development in disinfection of UV LED.

Recent research has proven that wavelength selection is essential to getting the most from UV LED disinfection systems. Utilizing both 365nm and 275nm wavelengths gives a synergistic effect that allows faster and more stable reactions. 

This light combination modifies both proteins and nucleotides, thereby inactivating both biological and microorganism materials. Disinfect surfaces with low heat emission, precise control, high intensity, and long operating life will enhance safety for the chemical, pharmaceutical, and cosmetic manufacturing and food processing. 

This new technological development is thrilling. There is a broad array of new applications in various sectors that cannot be foreseen. However, it is thrilling to watch this transformation as it slowly unfolds.
