People often ask what ozone is used for in water treatment. In Billerica, MA it is used at the Billerica Water Treatment Plant.
The plant, which opened May 18, 2006, draws water from the Concord River, the town’s water supply, and then screens it through a raw water pumping station.
The water is ozonated – treated with ozone– in order to remove the brown color. Ozone is stronger than chlorine, decomposes into oxygen and produces low to no concentrations of any carcinogenic by products, according to a public works report.
Color removal is a common application for ozone in drinking water treatment along with taste, odor, Fe, Mn and hydrogen sulfide removal. Ozone is also an excellent disinfectant for drinking water.
Spartan Environmental Technologies supplies ozone generator systems for drinking water and other applications.
