UV Water Sterilization

Chemical-free protection against water-borne pathogens such as bacteria, viruses & protozoa

Some Chinese residential complexes rely on ozone for water disinfection. This type of water treatment is problematic however, because ozonation provides no germicidal or disinfection to inhibit and prevent regrowth of these contaminants. To ensure that your water stays free of waterborne bacteria, viruses, and protozoa, Environment Assured recommends UV sterilization.

Ultraviolet (UV) sterilization is a highly effective way to neutralize microbes without the use of chemicals. The system protects against micro-organisms, bacteria and viruses by exposing water to a controlled rate of UV light waves. This deactivates the contaminants and ensures perfectly safe water – always.

Why UV Sterilization?

  • More effective than chlorine at inactivating dangerous microbial contamination
  • No chemicals or toxic residual by-products 
  • Does not change the taste, color, or odor of the water 
  • Fast-acting treatment, no water holding tanks needed
  • Easy installation
  • No storage or handling of chemicals

Environment Assured works with you to help select systems that fulfil your requirements and are also appropriate for local water conditions. We use the best-of-class proven technologies and materials to get your water the way you want it. Contact us for help selecting a UV system.
