The new system will comply with EPA 4-log virus disinfection standards
The town of Hillsborough, N.H., has chosen Atlantium Technologies Ltd.’s Hydro-Optic ultraviolet (UV) water disinfection system to disinfect for viruses as an alternative to using conventional chlorine.
Hillsborough draws municipal water from Loon Pond, a surface water supply containing high organic load. Dosing the water with enough chlorine to achieve U.S. Environmental Protection Agency (EPA) 4-log virus disinfection standards results in disinfection byproduct violations. The town has been under state orders to change their disinfection practices to reduce the threat of carcinogens in the water.
After completing several pilot projects attempting various technologies including carbon filters and chloramines, Hillsborough decided on Atlantium’s medium pressure UV solution. They chose the Atlantium UV solution for several reasons including small footprint; integrated control software that gives push-of-the-button compliance reports; and medium-pressure lamp technology that is efficient in all water temperatures and destroys virus repair mechanisms.
Hillsborough’s Atlantium unit will provide 3-log virus credit, with chlorine providing the remaining 1-log credit—resulting in a significant reduction of chlorine and no disinfection byproduct violations. Its design will provide full disinfection power even when the water quality goes down.
“When we invested several years ago in proving that UV can effectively achieve validated EPA 4-log virus credit, despite popular opinion, it was clear that we had a unique hydro-optic medium-pressure UV technology that could deliver the goods, and that it was only a matter of time before the marketplace would ‘see the light,’” said Benjie Kahn, Atlantium CEO.
