Ultraviolet is a process using extremely short wave-length light that can kill microorganisms (disinfection) or cleave organic molecules (photo oxidation) rendering them polarized or ionized and thus more easily removed from the water. Ultraviolet (UV) oxidation works in oxidizing natural contaminants existing in the water and is done through the addition of oxidizing agents such as hydrogen peroxide and ozone to the polluted groundwater. The polluted source is then flowed through a chamber where it is hit with ultraviolet radiation.
