In this guide, learn what a UV system is , how it works, its benefits , and why it can be a great choice for your residential pool.
☀️ What is a UV pool system?
A UV system is a device that uses ultraviolet light to disinfect pool water. It is installed in the filtration system and exposes the water to a high-intensity UV lamp as it passes through.
This light destroys or inactivates:
Bacteria
Viruses
Algae
Parasites such as cryptosporidium
💡 Important : The UV system does not completely replace chemicals, but it greatly reduces their use , while improving the overall effectiveness of disinfection.
🔬 How does a UV system work?
-
Water circulates through the pool's filtration system.
-
Before returning to the pool, it passes through a UV chamber where it is exposed to type C ultraviolet (UV-C) light.
-
This exposure destroys the DNA of microorganisms, rendering them harmless .
-
The water returns to the pool, purified and safe .
