How Does UV-C LED Disinfection Work?

Different types of UV-C disinfection can work depending on the scale of the solution being implemented. However, the principles of how UV-C disinfection works remain the same.

Due to the rapid development of the smartphone, we now have access to more advanced LED systems that can emit not just visible light but also infrared and UV.

An LED produces a pre-selected wavelength from a small amount of electricity. The LED then emits UV-C photons through the water that penetrate the cells and damage the nucleic acid in the microorganism DNA.   

As these cells cannot replicate, it renders the harmful microorganism inactive. As a result, UV-C LEDs allow for high-intensity radiation to kill the bacteria in seconds, and its effectiveness is measured in LOGs. 

Disinfection of Drinking Water

One area where UV-C LEDs are proving to be successful is in the disinfection of drinking water. 

UV-C LEDs are being to disinfect drinking water at various points in the treatment cycle, from source to consumption. It can take a few seconds for the water to become clean in a UV-C model, and the new technology allows for LEDs to placed at a different point to ensure decontamination.

It works initially when a water reservoir is exposed to a number of high-powered LEDs that disinfect the water. They emit powerful UV-C photons in the range of 200 – 280nm that pass through the water, stopping the bacteria in the water from being able to reproduce.

Many newer systems have taken advantage of the compact size of the LEDs and can disinfect at the end stage of the drinking water journey – ensuring complete disinfection. 

Water Treatment and Pathogen Control 

A recent paper released in Science of the Total Environment journal looked at various microbial disinfection methods for UV-LED water treatment systems. It found that UV-C LEDs were effective in the inactivation efficiency and energy consumption of UV-LEDs for pathogens at various wavelengths. 

As UV-C LEDs can select various wavelengths to target specific microorganism present in infected water and deactivate them, different pathogens and bacteria stop replicating when they have been exposed to different wavelengths.

What is LOG reduction?

LOG reduction is used to measure how thoroughly a decontamination process reduces the amount of contamination. 

For example, 1-log reduction means the number of bacteria is 10 times smaller, 2-log equals 100 times smaller, 3-log equals 1,000, and so on.
