How Does Ultra Violet Light Work?

UV rays can destroy 99.99% of harmful micro-organisms without adding chemicals or changing your water’s taste or odour. Ultraviolet light (UV) is a natural component of sunlight and is widely accepted as a reliable, efficient, and environmentally friendly method for water disinfection.

The UV lamp emits radiation at a 254nm wavelength – lethal to bacteria, viruses, and protozoa. As water flows through the sterilizer’s chamber, it is exposed to this UV light, which penetrates micro-organisms and disrupts their DNA, rendering them unable to reproduce or infect.

Chemicals and organic compounds may also absorb UV energy and break down into smaller, safer molecules. The result is clean, safe water without the use of chlorine or other harsh disinfectants.

For Optimal Performance:

• Replace UV bulbs annually, even if the lamp is still glowing – intensity diminishes over time

• Always filter water before UV treatment to remove particles that could block the light

• Ensure your UV system is properly sized for your water flow rate
