How UV Sterilization Works
UV 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. Currently, many major cities in Canada, 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.
UV-LED vs UV Lamps
The conventional technique for UV water treatment utilizes UV mercury lamps. However, there are serious concerns related to the environmental impacts and performance limitations of UV-lamps.
|Environmental Impact||Friendly||Mercury Used|
|Lifetime||10+ Years||1 Year|
|Hazards (eye, skin)||Safe||Dangerous|
|UV Source Replacement||None||Every Year|
The Acuva Way
Acuva's system takes water purification to the next level of efficiency and convenience by utilizing two well established and proven technologies: UV and LED. Recent advances in light emitting diodes (LED) technology have allowed LEDs to generate UV radiation at the wavelengths for microorganism inactivation.
Before entering the chamber, the source water is filtered through an integrated filter to remove particles and odor causing chemicals, enhancing water taste
The Acuva UV-LED chamber expose harmful microbial pathogens to the UV dose recommended by the NSF Standard. Our proprietary design allows for the UV rays to be concentrated directionally, maximizing deactivation effectiveness while minimizing power usage.
What is a LED?
A light emitting diode (LED) is a semiconductor material based light source. LEDs are small in size and much more energy efficient than alternative light sources.
What is UV?
Ultraviolet (UV) is the portion of the light spectrum with wavelengths from 10nm to 380nm, which is just shorter than the human eye can detect.
What are UV-LEDs used for?
UV-LEDs have many use cases, including the disinfection of water, physical surfaces, and even air.
Is UV safe?
UV is safe for use with the appropriate precautions and is already used for treatment of certain skin conditions of those with a Vitamin D deficiency. The Acuva system is enclosed and therefore does not result in any UV exposure.
How long do UV-LEDs last?
UV-LEDs last between five and ten years and have uniquely rugged characteristics allowing them to withstand impact. They also have no limit to how many times they can be turned on and off which increases efficiency and lifespan.
