Benefits of UV-LED

How UV Disinfection Works

UVC disinfection utilizes strong short-wavelength (250–280 nm) radiation to inactivate microorganisms by destroying the nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. This means any microbial contaminants are rendered unable to infect or reproduce to cause harm after exposure to UVC. This is achieved without the need for any chemicals.

UVC treatment is effective against microbial contaminants such as bacteria, cysts and viruses with appropriate doses. UVC disinfection can be applied to water, air and surface applications.

Currently, many major cities in Canada, The United States, and Europe, such as Vancouver, New York, and Paris have adopted UV as their primary water disinfection process, making UV one of the fastest growing water treatment technologies.

 

What is Log Reduction?

Log reduction is a measure of how many living microbes were eliminated from the water after treatment. An increment of 1-log corresponds to a reduction in concentration by a factor of 10.

UV-LED vs. UV Lamp Technology

The conventional technique for UV water and surface treatment utilizes UV mercury lamps. However, there are serious concerns related to the environmental impacts and performance limitations of UV-lamps.
