Ultraviolet (UV) Disinfection Equipment

Evoqua Water Technologies offers a complete range of ultraviolet (UV) disinfection solutions for industrial, commercial, aquatic and high-purity applications.

UV irradiation can be used for multiple purposes in water treatment, but is primarily employed as a disinfection process that inactivates waterborne pathogens without chemicals. For other applications, UV is used for the removal of organic and inorganic chemicals, including chlorine, chloramines, ozone and Total Organic Carbon (TOC). When combined with oxidants such as ozone or hydrogen peroxide, or semiconductors such as titanium dioxide, UV can be used for the oxidation of refractory chemicals such as chlorinated solvents, taste and odor compounds, and other emerging contaminants.

The UV Technology Advantage
The advantages of UV disinfection have been realized and the technology successfully employed world wide for decades. The primary advantage of being able to effectively control all types of microorganisms, including those which are chlorine-resistant, without chemicals has numerous benefits for municipal, industrial, commercial and aquatics customers. In addition to disinfection, UV is also very effective for TOC removal, destruction of chlorine, chloramines and ozone.  

  • Improves disinfection efficacy
  • Reduces environmental, health and safety risks
  • Eliminates formation of disinfection by-products
  • Does not alter the aesthetic qualities of the water
  • Eliminates any concerns with "over dosing"
