Transforming Water, Enriching Life with Validated Technology

​Ultraviolet (UV) irradiation is used for multifunctional purposes.  UV is most commonly used as an environmentally friendly alternative to chemical disinfection. It’s one of the most effective methods for inactivating harmful pathogens such as Listeria, E.coli, Giardia and chlorine tolerant pathogens like Cryptosporidium.  Read more about how it works.UV is also used for removal of organic and inorganic contaminants, including chlorine, ozone and Total Organic Carbon (TOC).  UV used in conjunction with an Advanced Oxidation Process (AOP) will remove Compounds of Emerging Concerns (CEC’s), Synthetic Organics (SO’s), Endocrine Disruptor Compounds (EDC’s) and Personal and Pharmaceutical Care Products (PPCP’s), as well as various taste and odor compounds from water.



ETS-UV disinfection systems are used in a wide variety of markets and applications including:

Why ETS-UV?ets-pic#2


  • Closed vessel UV, no open water source
  • Reduced UV exposure
  • Constructed from materials that will not produce harmful carcinogenic byproducts

Compact footprint, easy installation

  • Lower installation costs which allows for quicker and easier installations
  • Provides solutions for new installations or retro fit
  • Flexibility of installation either horizontally or vertically to accommodate the most challenging footprint restrictions

Reduced Maintenance

  • Wiping mechanism is external to the water
  • Wiper rings can be replaced without removing wiping carriage from chamber
  • Individual lamp and sleeve replacement offers a twist and lock connection
  • Access hatch available on many models

Validations & Approvals

Many of our systems have been validated per rigorous industry specific standards.

  • Validation for drinking water per USEPA UVDGM and NSF/ANSI Standard 61
  • NSF 50 Listed (Recreational water)
  • Validated to the 2003 and 2012 NWRI Reuse Guidelines
  • Meets the requirements of all state and provincial codes and the Model Aquatic Health Code for recreational water
  • Meets all the requirements in the FDA’s Grade A Pasteurized Milk Ordinance (PMO) for UV pasteurized equivalent water in dairy facilities
We apply the science of UV in each project.  All efforts are made to qualify and size your project properly.  Key factors are considered to include ultraviolet transmittance (UVT), dose requirements and regulatory standards which may apply to your application.
