UV Lights

Ultraviolet (UV) lights utilize high levels of ultraviolet light to inactivate pathogens, rendering them harmless.

🛈 How it works:

➤ Untreated water enters one end of the UV light

➤ The water is exposed to high levels of UV light, inactivating pathogens

➤ Treated water flows out of the other end of the UV light

➤ The UV bulb requires yearly replacement

The UV bulb will continue burning after 365 days have elapsed, but the bulb loses intensity over time and should be replaced at the 1 year mark, to ensure the unit remains effective at treating pathogens.

The UV light exposes the water to high intensity light in the ultraviolet spectrum (254nm), which damages the DNA of living organisms and inactivates any pathogens in the water, rendering them harmless.

UV lights require the water to be clear to function properly. If the water is turbid (discolored), this can prevent the light from reaching every part of the unit with enough intensity to properly treat pathogens.

Municipal water supplies frequently use ultraviolet light in combination with chlorine to treat pathogens in the water, due to some pathogens being much more susceptible to Ultraviolet light.
