Inactivate pathogens, remove contaminants, meet sustainability objectives, and more!
UV is a proven, safe, and reliable method of disinfection for municipal drinking water, wastewater, and water reuse applications. The highly efficient and sustainable process does not involve the use of added chemicals and reduces the risk of disinfection by-products by lowering chemical disinfection requirements. It is effective as both a primary and secondary barrier disinfection, installed post chlorination specifically to target chlorine-resistant microorganisms. UV is also widely used as part of a multi-barrier treatment strategy, used as the primary disinfectant, followed by the addition of residual chlorine to protect the treated water as it travels through the distribution network.
A SOLUTION FOR A VARIETY OF MARKETS AND APPLICATIONS
The Agriculture, Aquaculture, Beverage, Food, Data Centers, Microelectronics, Marine, and Pharmaceutical markets are just a few of the industries that can benefit from UV technology. UV is highly versatile, including but not limited to the applications below:

WHAT IS ULTRAVIOLET LIGHT?
Ultraviolet (UV) light is energy within the electromagnetic spectrum that has shorter wavelengths than that which are visible to the human eye. UV light is a range of electromagnetic waves from 100 to 400 nanometers (between x-ray and visible light). The division of UV light is classified as Vacuum UV (100–200 nm), UV-C (200–280 nm), UV-B (280–315 nm) and UV-A (315–400 nm). The energy waves provided in the UV-C spectrum demonstrate germicidal efficiencies that provide highly effective disinfection.
HOW UV DISINFECTION WORKS
Evoqua UV disinfection generator systems undergo third-party validation testing in accordance with the UVDGM (USEPA, 2006). Validated products are tested to confirm a minimum inactivation equivalent of 3 log (99.9%) for microorganisms in accordance with NSF/ANSI 50 and the UVDGM. Performance is not claimed nor implied for any product not yet validated; unvalidated products use single point summation calculations to provide delivered dose recommendations. Performance limitations depend on feed conditions, overall installed system design, and operation and maintenance processes; please refer to Operations Manuals.
