When properly designed, ultraviolet (UV) light is an effective method for de-chlorinating water. There are abundant Technical Papers explaining the mechanisms and theory behind UV light chlorine and chloramines reduction. The only remaining question is: "When is UV a practical method over conventional methods?"

Conventional methods de-chlorinate water using granulated activated charcoal (GAC), sodium bisulfate, or sodium metabisulfite. These methods remove chlorine by either absorption or through chemical reactions, and both introduce drawbacks that must be managed. UV light de-chlorination method on the other hand has no drawbacks. It's a simple, single pass, no additive, no by-product producing process. And UV light has additional benefits, performing significant amounts of microbial disinfection and destruction of organic compounds. The conventional methods are unable to do likewise.

Chlorine is a capable disinfectant and plays an important role in ensuring the health and safety of water for consumption and for water recreation. However, there are many applications where chlorine is no longer necessary, and in reality the presence of chlorine is a great disadvantage.

Chlorine is corrosive, and damages a number of critical water filtering systems such as RO membranes and deionization resins. Chlorine greatly affects odor and taste of products manufactured for consumption, such as beverages. Chlorine can also affect the color of the product. The presence of chlorine in water for medical procedures (kidney dialysis) is unhealthy and potentially dangerous. These are just a few of the reasons why products and processes exist to remove chlorine from water.
