The most popular chemical used for water disinfection is chlorine which, is largely effective except that there are some microbial pathogens, such as Cryptosporidium and Giardia, that are resistant to disinfectant, also chlorine when added to our water, combines with other natural compounds to form Trihalomethanes (chlorination byproducts), or THMs. These chlorine byproducts trigger the production of free radicals in the body, causing cell damage, and are said to be carcinogenic.
Due to these reasons world over Water treatment operators, both large and small, are turning to ultraviolet radiation (UV) as an alternative to reduce or eliminate the use of chlorine for disinfection since Ultraviolet (UV) water treatment systems compared to traditional water treatment methods, are reliable, effective, completely chemical-free, environmental-friendly, and create no harmful by-products.
