A reference standard in wastewater UV disinfection

Robust, Renowned, and Proven

The TrojanUV3000Plus® is one of the reasons why UV disinfection is now a favored technology in wastewater treatment. Often touted as a flagship UV system, it has demonstrated effective and reliable performance around the world. In fact, over 2,000 municipalities rely on it to disinfect over 30 billion gallons of wastewater every day.

The TrojanUV3000Plus has been validated through regulatory-endorsed microbial testing. Through this testing, performance data has been generated for UV dose delivery to disinfect pathogens Escherichia coli (E. coli ) and fecal coliform.

Key Features and Benefits


Energy-efficient Amalgam Lamp Technology

Our high-efficiency amalgam lamps deliver stable UV output throughout a wide array of water qualities and temperatures, all while drawing less energy than competitive low-pressure high-output lamp-based UV systems. These lamps have been shown to deliver 98% of full UV output after more than one year of use, and have 20% less decline in UV output after 12,000 hours of use compared to competitive UV lamps.

Automatic Lamp Sleeve Cleaning

The patented ActiClean® system helps maintain at least 95% UV transmittance, ensuring consistent and optimal UV output. Operators need not worry about manually cleaning, as all quartz sleeves and intensity sensors are cleaned automatically, without disrupting disinfection.

Flexible Installation & Expansion

Modular, compact design allows cost-effective installation into existing effluent channels and chlorine contact chambers. When the time comes to meet new regulations and increase flow capacity, simply add more banks. What’s more – the entire system can be installed outdoors to reduce capital costs, no building, shelter or HVAC required.

Easy to Maintain

UV lamps can be easily and quickly replaced without tools, and an intuitive quick connect makes refilling the ActiClean Gel fast and simple. And thanks to the system’s modularity, routine maintenance can be performed on one module without disrupting disinfection performance.

Self-contained UV Modules

Module-mounted lamp drivers allow for compact installation, convection cooling and protect wires and cables from exposure to effluent and UV light. They are housed right in the module, reducing system footprint, minimizing installation time and costs and eliminating the need for separate external cabinets.


Customer Stories

Converting From Chlorine to UV

In Mexico, the State Water Commission of Jalisco (CEA Jalisco) is responsible for several municipal wastewater treatment plants discharging into Lake Chapala. The majority of these plants – including the one in San Juan Cosala – were disinfecting with chlorine gas. However, the growing concerns over disinfection by-products negatively impacting the aquatic life prompted CEA Jalisco to evaluate other disinfection options, including UV.
