TrojanUVSigna UV Disinfection System

Overview

The TrojanUVSigna UV Disinfection System is an engineered, medium- to large-scale ultraviolet (UV-C) water disinfection platform designed for municipal wastewater treatment plants requiring robust, regulatory-compliant pathogen inactivation. Operating on the principle of germicidal irradiation at 254 nm, the system delivers precise UV dose delivery through submerged, low-pressure high-output (LP-HO) lamp arrays housed in stainless steel reaction chambers. Unlike conventional UV systems relying on mechanical wipers or frequent lamp cycling, the TrojanUVSigna integrates TrojanUV Solo Lamp™ technology—a proprietary single-ended, electrodeless UV lamp design that eliminates filament degradation and extends operational life beyond 16,000 hours under continuous duty. This architecture reduces lamp replacement frequency by up to 50% compared to standard LP lamps and minimizes maintenance-induced downtime. The system is validated per USEPA UV Disinfection Guidance Manual protocols and supports full-scale implementation in both secondary and tertiary effluent streams with turbidity ≤ 15 NTU and UV transmittance ≥ 55%.

Key Features

• Integrated TrojanUV Solo Lamp™ technology—electrodeless, single-ended low-pressure UV lamps delivering stable 254 nm output with >95% intensity retention after 12,000 hours
• Modular reactor design with field-installable, hydraulically balanced chamber units scalable from 10 to 300 MGD (38,000–1,135,000 m³/d)
• Real-time UV intensity monitoring via calibrated quartz-sheathed sensors positioned upstream and downstream of each lamp row
• Self-cleaning quartz sleeves with integrated air-pulse cleaning system—no manual intervention required between scheduled maintenance intervals
• Redundant PLC-based control architecture compliant with IEC 61508 SIL 2 for safety-critical operation
• Full integration with plant SCADA via Modbus TCP/IP or OPC UA; optional HART-enabled analog outputs for 4–20 mA UV dose feedback

Sample Compatibility & Compliance

The TrojanUVSigna is certified for use with secondary and tertiary wastewater effluents meeting standard discharge criteria per ISO 10500:2020 (Water quality — Guidelines for UV disinfection of wastewater) and NSF/ANSI 55 Class A requirements. It has been independently validated for ≥4-log reduction of Escherichia coli, Giardia lamblia, and Cryptosporidium parvum under worst-case hydraulic and water quality conditions. The system complies with ASME B31.4 piping standards for UV chamber construction and meets UL 61010-1 and CE Machinery Directive 2006/42/EC for electrical safety. All firmware and operational logs support audit-ready data integrity per FDA 21 CFR Part 11 when configured with electronic signature modules.

Software & Data Management

TrojanUVSigna operates with TrojanUV Manager™ v5.2—a web-accessible supervisory software platform supporting role-based user permissions (admin, operator, technician). The software provides real-time dose calculation using validated bioassay-derived fluence-response models, automatic lamp aging compensation, and predictive maintenance alerts based on cumulative lamp hours and sensor drift trends. Historical UV dose, flow rate, intensity, and sleeve fouling index data are stored locally for ≥18 months and exportable in CSV or XML formats compatible with LIMS and enterprise asset management (EAM) systems. Audit trails record all parameter changes, login events, and alarm acknowledgments with UTC timestamps and user IDs—fully traceable for GLP/GMP or ISO 17025 accreditation audits.

Applications

• Municipal wastewater reclamation facilities requiring Class A reclaimed water for irrigation, industrial reuse, or groundwater recharge
• Large-volume tertiary treatment trains prior to surface water discharge under NPDES permit limits
• Combined sewer overflow (CSO) and stormwater treatment basins requiring rapid, chemical-free pathogen control during wet-weather events
• Membrane bioreactor (MBR) effluent polishing where chlorine-resistant organisms pose compliance risk
• Industrial pretreatment systems serving food processing, pharmaceutical, or pulp-and-paper facilities with stringent microbiological discharge requirements

FAQ

What UV dose range is supported by the TrojanUVSigna system?

The system delivers adjustable nominal doses from 20 to 120 mJ/cm², dynamically adjusted in real time based on flow rate, UV transmittance, and lamp output—validated across the full operating envelope per USEPA UV validation protocol.
Is third-party validation documentation available for regulatory submittals?

Yes—full hydraulic and microbiological validation reports, including BioDose™ testing results and CFD modeling summaries, are provided upon system commissioning and meet requirements for state primacy agency review.
How does the air-pulse cleaning system differ from traditional mechanical wipers?

It uses precisely timed bursts of compressed air directed tangentially across quartz sleeves, removing biofilm and particulate deposits without contact, eliminating wear-related failures and reducing maintenance labor by >70% annually.
Can TrojanUVSigna integrate with existing PLC networks without protocol conversion hardware?

Yes—the embedded controller natively supports Modbus TCP/IP, EtherNet/IP, and ProfiNet; no gateway or protocol translator is required for direct integration into most modern DCS or SCADA infrastructures.
What is the expected service life of the TrojanUV Solo Lamp™ under continuous operation?

Rated for ≥16,000 hours at 25°C ambient with <5% lumen depreciation—verified through accelerated life testing per IES LM-65-22 and aligned with IEC 62471 photobiological safety classification.
