Ultraviolet Systems

Ultraviolet (UV) systems are used for disinfection purposes. The ultraviolet method rapidly and effectively eliminates microorganisms in water without the use of heat or chemicals.

UV devices use light at specific wavelengths to damage the DNA structure of bacteria, viruses, fungi, mold spores, and other microorganisms in the water, rendering them ineffective. For these microorganisms to be killed, the UV light must directly strike them. Therefore, before water enters a UV system, parameters such as suspended solids and turbidity must be removed.

Another important consideration is to install the system as close as possible to its final point of use. In addition, the treated water should not be transferred to a separate open-air unit and must be used immediately. Ultraviolet lamps should be replaced after approximately 9,000 hours of use, although this duration may vary according to the manufacturer.

Ultraviolet systems are easy to implement, produce no by-products, do not alter the taste of water, have high disinfection capabilities, do not create corrosive substances, and are economical.
