Ultraviolet technology can be more effective than chemicals in destroying certain waterborne contaminants without altering the taste of water. This makes it a practical process for treating water used for drinking and food preparation. UV light penetrates germs and disrupts their DNA, preventing them from multiplying. UV disinfection has many advantages over other methods because UV systems can be compact and easy to install. UV does not require holding tanks or long reaction times. UV can also be used in conjunction with other water treatment methods.

The UV disinfection process is quick, but different germs require different amounts of UV energy, or dosages to be destroyed. UV units should be installed after any water pre-treatment process, just before the cold and hot branch lines. If in doubt about the size of a UV unit that is needed, always use a larger unit rather than a smaller unit. Normally an 8 gpm UV unit will be adequate for an average size house. UV should be installed as close as possible to the dispensing point. UV disinfection systems like Sterilight and Pura are very quickly gaining ground on other conventional disinfection processes because it is effective, environmentally friendly and economical. UV does not change the taste of water nor does it add anything to it. It is the ideal choice for disinfecting water.
