Ultraviolet (UV) disinfection technology has been the star performer in water and air treatment over the past two decades, due in part to its ability to provide treatment without the use of harmful chemicals.

UV represents wavelengths that fall between visible light and x-ray on the electAromagnetic spectrum. The UV range can be further divided into UV-A, UV-B, UV-C, and Vacuum-UV. The UV-C portion represents wavelengths from 200 nm - 280 nm, the wavelength used in our LED disinfection products.

UV-C photons penetrate cells and damage the nucleic acid, rendering them incapable of reproduction, or microbiologically inactive. This process occurs in nature; the sun emits UV rays that perform this way. 

At AquiSense, we use Light Emitting Diodes (LEDs) to generate high levels of UV-C photons. The rays are directed at viruses, bacteria and other pathogens within water and air, or on surfaces to render those pathogens harmless in seconds.

UV-C LED Technology - The Next Revolution

In much the same way that LEDs have revolutionised the display and lighting industries, UV-C LED technology is set to provide new, improved, and expanded solutions in both air and water treatment. Dual barrier, post-filtration protection is now available where mercury-based systems could not previously have been conceivably used.

UVC-LED Basics

An LED produces a selected wavelength from a small amount electricity. Depending on the composition of the LED it can produce anywhere from infrared, visible, and now UV-C wavelengths.

The side view of the LED shows that as power passes through the LED layers,
it activates the desired wavelength.

The LED is then packaged to allow for electrical connection, thermal management,

 and physical protection. This helps maintain efficiency for the LED output and lamp life.

These LEDs can then be integrated into various systems to treat water, air, and surfaces.
These systems also work with the LED packaging to disperse heat and improve
efficiency of the disinfection process.
