Image of a TrojanUVSigna


A revolutionary advancement in wastewater treatment

Industry-defining Innovation

The TrojanUVSigna® incorporates innovations, including TrojanUV Solo Lamp® Technology, to reduce the total cost of ownership and drastically simplify operation and maintenance. It is an ideal solution for wastewater treatment plants in need of revolutionary UV technology.

The TrojanUVSigna 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.

    Key Features and Benefits

    TrojanUVSigna two-row banks in wastewater effluent channel

    Designed to Fit Into Existing Channels

    The way in which water enters the UV system is controlled in such a way that stringent tolerances on concrete channel walls are not required, making chlorine contact tank and UV channel retrofits simpler. Retrofits can accommodate existing water level profile and head loss.

    Automatic Lamp Sleeve Cleaning

    Thanks to the patented ActiClean® sleeve cleaning system, quartz sleeves and intensity sensors are cleaned regularly without disrupting treatment – there’s no need to shut down the UV system or remove lamps for routine cleaning. This dual-action cleaning system uses mechanical wiping in conjunction with a cleaning solution contained within wiper canisters surrounding the quartz sleeves.

    TrojanUV Solo Lamp

    Low Lamp Count + High Electrical Efficiency

    Low-pressure lamps offer high efficiency and long lamp life, medium-pressure lamps have higher UV output – the TrojanUV Solo Lamp combines the best features of both. The end result is a compact and modular UV system unlike any other.

    Maintenance Made Simple

    Routine maintenance, including changing lamps and refilling ActiClean Gel, can be performed while banks are in the channel. An Automatic Raising Mechanism (ARM) makes other tasks, such as channel maintenance and winterization, easier.

    Enhanced Water Level Management

    Water level is managed using light locks in combination with the downstream water level controller. Light locks eliminate the need for complex channel designs, such as stepped channels, and help provide the highest treatment level over a wide range of flow rates and water levels.
