Ultraviolet systems are a perfect supplement to chemical water sanitation products and reduce the amount of chlorine required as well as killing all viruses, bacteria and algae. There are several bacteria such as cryptosporidium that are resistant to chlorine but a UV system deals with these.
UV-C is an invisible light with a wavelength shorter than that of visible light but longer than X-rays. Its connection to water sanitation was discovered more than 100 years ago when European scientists learned the top surface of lake water was sterile when exposed to sunlight. This eventually led to the invention of UV-C bulbs. The spectrum of UV light can be subdivided into four main categories, UV-A, UV-B, UV-C and Vacuum UV. The area between 280 and 100 nanometers is UV-C, also known as germicidal light.
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 secondary halogen or copper system. The effects of UV-C are immediate and do not alter the water’s composition.
These systems can be quickly fitted to existing pool systems space permitting.
