Because you can’t see, smell or taste harmful microbes in your water, it is important to properly disinfect your water supply. So which is better? UV light or chlorine?

Both constant chlorination and UV disinfection are recognized by authorities like the EPA and Health Canada as effective means of disinfection. UV adoption, though, is on the rise because it is effective against a broader range of microorganisms, including protozoa, like Cryptosporidium and Giardia. It is also a chemical-free, environmentally-friendly solution.

While Chlorine has been used since the early 1900s, UV disinfection (in more primitive terms) has been used for centuries. Once it was discovered that UV wavelengths had germicidal characteristics, that technology was harnessed and turned into the UV water disinfection that we have today.

Ultraviolet light is a sophisticated disinfection solution, but it doesn’t require an overly technical explanation. Light of a specific wavelength is passed through the water, inactivating any pathogens that are present. Because they are inactivated, microbes can no longer multiply, which means they can’t cause infection.

For the best results and minimal maintenance, UV systems do require some pre-treatment. At the least, this includes a sediment filter, which is often included with the newer, high quality systems. But for the most part, UV systems require less maintenance than a chlorinator, so you won’t be making countless nuisance service calls that take you away from the business of selling. However, depending on the quality of the water, the quartz sleeve will require periodic cleaning.
This can often be coincided with the annual lamp change. With a managed service schedule, it’s possible to balance service satisfaction and customer loyalty.
