TrojanUVFlex for Drinking Water

Utilizing revolutionary TrojanUV Solo Lamp™ Technology, the TrojanUVFlex™ provides municipalities with energy-efficient UV disinfection for their drinking water in an extremely compact footprint.

Suited for Drinking Water Treatment Around the World

The TrojanUVFlex™ design and advanced third-party validations ensure that a UV system can be designed to deliver disinfection for regional treatment challenges. These include meeting all disinfection credits mandated by the Surface Water Treatment Rule, Long Term 2 Enhanced Surface Water Treatment Rule, and Groundwater Rule in the U.S., as well as various treatment targets mandated in countries around the world.

TrojanUVFlex Chamber

Efficient Operation & Easy Maintenance, With a Compact Footprint

Powerful and highly energy-efficient Solo Lamps lead to a low lamp count which, in turn, provides other benefits such as fewer associated components (e.g., lamp drivers and sleeves), and a smaller UV chamber, reducing footprint by up to 50% that of other low-pressure UV disinfection systems.

Lamps are installed perpendicular to flow allowing for individual sub-sections of lamps in a chamber to be turned on and off without causing “dead zones”. This minimizes the number of lamps needed for treatment at a given time.

Advanced Solo Lamp™ drivers can also reduce (“dim”) each UV lamp’s output to 30% of its maximum output capability. These features maximize the range of UV-intensity outputs for a TrojanUVFlex™ system and provides end-users with dynamic and energy-efficient UV disinfection for any treatment condition.

Application Flexibility

The TrojanUVFlex™ is also used in wastewater and advanced oxidation applications. Learn more about the wastewater system here and the advanced oxidation system here.

Low Lamp Count & High Electrical Efficiency
The revolutionary TrojanUV Solo Lamp™ combines the benefits of low- and medium-pressure lamps, providing low power consumption (1/3 the energy of medium-pressure lamps), low lamp count, long lamp life (>15,000 hours), and reduced maintenance.

Optimized Power Consumption
Banks of lamps are turned on/off based on UV demand. The advanced Solo Lamp™ driver enables lamp dimming from 100 to 30% power and has built-in diagnostic capability for easy troubleshooting.

Compact Footprint & Flexible Installation
The small chamber footprint simplifies indoor retrofit installations and reduces construction costs. Chambers can be installed either horizontally or vertically, making integration into existing piping straightforward and allowing service access from any direction.

Less Time Spent Changing Lamps
Fewer lamps, long lamp life and easy change-outs save time and money.

Proven Disinfection Performance
Staggard, cross-flow lamp array – optimized through computational fluid dynamics – maximizes disinfection performance and increases system resilience with continued disinfection in the event of a lamp failure.

Mechanical Sleeve Cleaning
Without removing equipment or disrupting disinfection, the automatic sleeve wiping saves time and ensures the maximum UV output is available for disinfection.

Future Expandability
Chambers can be manufactured with additional banks to accommodate future treatment capacity or advanced oxidation capability Providing a solution that meets current requirements while planning for future needs.

Advanced Validation
Chambers are validated across a wide range of treatment conditions in accordance with the National Water Research Institute (NWRI) and United States Environmental Protection Agency’s Ultraviolet Disinfection Guidance Manual (UVDGM) providing high-intensity UV disinfection including up to 4-log inactivation of Escherichia coli (E.coli), Cryptosporidium, Giardia, and adenovirus types 2 and 40.

  • UV Water Treatment - Cryptosporidium Barrier

    Cryptosporidium is a harmful protozoa that can cause severe illness and even death in some individuals. Fortunately, this chlorine-resistant parasite can be easily inactivated with a low UV dose.


  • UV Water Treatment - Primary Disinfection

    By employing UV as the primary disinfectant, the required chemical contact time can be reduced or eliminated (dependant upon local regulations).


  • UV Water Treatment - Multi-Barrier Strategy

    UV is a perfect fit as an additional barrier in a multi-barrier strategy to provide additional public safety.


  • UV Water Treatment - Giardia Barrier

    Giardia can be found worldwide and is one of the most common waterborne parasites. Low UV doses can inactivate Giardia without forming disinfection by-products.


  • UV Water Treatment - Virus Barrier

    There are a variety of viruses that may be present in water that, if not treated, may present a health risk to consumers. Examples include adenovirus, rotavirus, poliovirus, and coxsackievirus.
