Xylem’s ETS-UV™ brand manufactures industry leading ultraviolet (UV) disinfection systems. ETS-UV™ systems are highly efficient, easy to maintain and are validated for performance per rigorous industry standards for drinking water, water reuse and recreational water applications. ETS-UV™ systems are validated by a 3rd party per NWRI Reuse Guidelines, through a bioassay which rigorously tests the UV system under a wide range of water quality conditions to identify system performance and enable accurate sizing and performance guarantees. UV disinfection is one of the most effective methods for inactivating harmful pathogens such as Listeria, E. coli, Giardia and chlorine tolerant pathogens like Cryptosporidium.
