UV sanitation systems eliminate chlorine-resistant microorganisms,
which are common causes of pool closures.
These systems reproduce UV radiation inside light chambers via powerful lamps, which emit germicidal UV-C light that is used to disinfect pool and spa water.
Facilities equipped with these systems consume fewer chemicals and allow sanitizers to be more effective.
How much more effective depends on the water’s hardness, pH and other water chemistry factors.
UV-C causes permanent damage to a number of microorganisms almost instantly as the water circulates through the light chamber.
By disrupting the microorganism’s DNA, protozoans, viruses and bacteria are unable to replicate and remain inert.
This light, however, works only on water that flows through the chamber.
Water in dead zones isn’t treated by the light and the light does not act as a residual, thus the need for the presence of a halogen.
The effects of UV-C are immediate and do not alter the water’s composition.
