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. These include:
- High operating power and voltage
- Short lifetime resulting in higher operating costs
- Inability to frequently turn them on/off meaning the lamp is on when there is no water flow
- Cylindrical shape of the UV-lamps limits the chamber's design and efficiency
- Presence of mercury, which will contaminate your water supply if the fragile UV lamp is broken
The Acuva Way
The Acuva system takes water purification to the next level of efficiency and convenience by utilizing two well established and proven technologies: UV and LED for water treatment. Recent advances in light emitting diodes (LED) technology have allowed LEDs to generate UV radiation at the wavelengths for microorganism inactivation.
Water supply, which is at risk of microbial contamination
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 different materials produce different light wavelengths.
What is UV?
Ultraviolet (UV) is the portion of the light spectrum from 10nm to 380nm wavelengths just shorter than the human visible range.
What are UV-LEDs used for?
UV-LEDs have many uses because they can be used singly or in arrays of multiple LEDs for larger applications where disinfection of surfaces, water and air is required.
Is UV safe?
UV is safe for use with the appropriate precautions and is already used in 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 for between five and ten years in applications and also have uniquely rugged characteristics and can withstand impacts. They also have no limit to how many times they may be turned on and off, so you have access to safe drinking water whenever you need it.
