New Hampshire Town Selects Disinfection Solution

The town of Hillsborough, N.H., has chosen Atlantium Technologies Ltd.’s Hydro-Optic ultraviolet (UV) water disinfection system to disinfect for viruses.

Hillsborough draws municipal water from Loon Pond, a surface water supply containing high organic load. Dosing the water with enough chlorine to achieve the U.S. Environmental Protection Agency 4-log virus disinfection standards results in disinfection by-product violations. The town have 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. The town 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 by-product violations. Its design will provide full disinfection power even when the water quality goes down.
