TrojanUV3000B installation at a wastewater treatment plant in Ontario, Canada


An operator-friendly, economical UV treatment system for small wastewater plants

Simple and Reliable Wastewater Treatment

The TrojanUV3000®B is a simple, yet robust system designed for small wastewater treatment plants that are looking to treat 1 – 5 MGD (158 – 789 m3/hr). The system is straightforward to use and requires minimal operator involvement thanks to its modular design and proven components.

    Key Features and Benefits

    Streamlined Installation

    The TrojanUV3000B can be easily retrofitted into existing chlorine contact tanks and effluent channels, and comes pre-tested, pre-assembled and pre-wired to minimize installation costs. All components can be installed outdoors, eliminating the need for and costs of additional buildings.

    Advanced, Self-Contained UV Modules

    Space-saving electronic lamp drivers are housed right in the modules – not in separate external cabinets – and are cooled by convection. All module wiring is pre-installed, factory-tested, and enclosed inside a waterproof frame.

    Operator-friendly Design

    Modules are lightweight and electrically separate, allowing a single module to be removed without disrupting flow or taking the system offline. Lamps are guaranteed for 12,000 hours of operation and can be replaced without tools. A UV lamp status indicator provides at-a-glance monitoring and helps determine when replacement is needed.

    Proven Performance

    The TrojanUV3000B has been validated through microbial testing. Through this testing, performance data has been generated for UV dose delivery to inactivate microorganisms Escherichia coli (E. coli ) and fecal coliform.

      Flow Pacing

      The System Control Center (SCC) provides digital display of bank status, lamp hours, and UV intensity. Individual banks can be turned on and off automatically in response to variations in flow rate (based on a flow meter signal). This flow pacing maximizes operating efficiency by matching UV output to treatment requirements and reducing electrical consumption during periods of low flow.
