Overview
The HACH TrojanUV3000B is a compact, modular ultraviolet (UV) disinfection system engineered for reliable, energy-efficient secondary effluent disinfection in small- to medium-capacity wastewater treatment plants (WWTPs). It operates on the principle of germicidal UV-C irradiation (254 nm wavelength), which inactivates bacteria, viruses, and protozoan pathogens—including Giardia lamblia and Cryptosporidium—by disrupting their DNA/RNA replication capacity. Unlike chemical disinfectants, UV treatment introduces no residual byproducts, avoids chlorine-resistant pathogen concerns, and eliminates the need for hazardous chemical storage or handling. The system is designed for plug-and-play integration into existing effluent channels or open-channel flow conduits, with hydraulic performance validated per US EPA UV Guidance Manual (2006) and NSF/ANSI 55 Class A standards.
Key Features
- Energy-Optimized UV Output: Equipped with high-output, low-pressure (LP) amalgam UV lamps delivering stable 254 nm emission across variable flow rates; lamp power modulation synchronized with real-time flow measurement ensures consistent UV dose delivery while minimizing electrical consumption.
- Intelligent Dose Control: Integrated UV transmittance (UVT) sensor and flow meter feed data to the Trojan AquaSuite™ B controller, enabling dynamic lamp bank activation/deactivation to maintain target fluence (typically 30–100 mJ/cm²) without over-dosing.
- Robust Mechanical Design: Stainless steel (316L) reactor chamber with polished interior surface; IP66-rated control panel; corrosion-resistant quartz sleeves; field-serviceable lamp modules requiring no specialized tools for replacement.
- Low Maintenance Architecture: Lamp life rated at ≥12,000 hours under nominal operating conditions; automatic wiper system available as optional upgrade for high-fouling applications; self-diagnostic routines monitor lamp status, sleeve fouling, and sensor integrity.
- Regulatory-Ready Operation: Compliant with US EPA UV Disinfection Guidance Manual requirements for validation, monitoring, and reporting; supports audit-ready event logging aligned with GLP/GMP principles and FDA 21 CFR Part 11 data integrity expectations when paired with optional secure software packages.
Sample Compatibility & Compliance
The TrojanUV3000B is validated for use with secondary-treated municipal wastewater effluent meeting typical quality benchmarks: UV transmittance ≥75%, turbidity ≤10 NTU, and total suspended solids (TSS) ≤15 mg/L. It is not intended for raw or primary effluent without pretreatment. The system conforms to key international standards including NSF/ANSI 55 Class A (for microbiological reduction), ISO 14001 environmental management compatibility, and CE marking for electromagnetic compatibility (EMC) and low-voltage directive compliance. Validation protocols follow the USEPA’s UV Disinfection Technology Verification Protocol and are supported by third-party bioassay testing using MS2 coliphage or Bacillus subtilis spores.
Software & Data Management
The embedded AquaSuite™ B controller provides local HMI operation via touchscreen interface and supports remote access through Modbus TCP/IP or Ethernet/IP protocols. All operational parameters—including instantaneous UV dose, lamp output %, UVT, flow rate, and alarm history—are timestamped and stored onboard for ≥90 days. Data export is supported via USB or CSV file transfer. Optional AquaSuite Connect cloud service enables secure remote monitoring, predictive maintenance alerts, and automated report generation compliant with state-level DMR (Discharge Monitoring Report) submission formats. Audit trails include user login events, parameter changes, and system resets—fully traceable and non-erasable per regulatory data retention guidelines.
Applications
- Small municipal wastewater treatment facilities (design flows: 0.5–10 MGD / 2–40 L/s)
- Decentralized community systems and clustered housing developments
- Reuse applications requiring tertiary disinfection for irrigation or industrial makeup water
- Emergency response installations where rapid deployment and minimal footprint are critical
- Facilities transitioning from chlorine-based disinfection to meet emerging DBP (disinfection by-product) regulations
FAQ
What is the minimum required UV transmittance (UVT) for effective operation?
The system is designed for influent UVT ≥75% at 254 nm; performance modeling and validation assume this baseline. Lower UVT requires hydraulic or lamp configuration adjustments verified during site-specific validation.
Does the TrojanUV3000B require annual third-party validation?
Yes—per US EPA and most state regulatory agencies, full-scale bioassay validation must be conducted annually or after major component replacement to confirm delivered dose meets permit requirements.
Can the system integrate with existing SCADA infrastructure?
Yes—standard Modbus RTU/TCP and BACnet MS/TP communication protocols are supported; custom driver development is available upon request.
Is ozone generation a concern with LP UV lamps?
No—low-pressure mercury lamps emit negligible ozone; the system does not require ozone destruct units or ventilation beyond standard equipment room specifications.
What documentation is provided for regulatory submissions?
HACH supplies a comprehensive validation dossier including hydraulic profile reports, lamp output calibration certificates, UVT correlation data, and sample DMR-ready log templates—all formatted for direct submission to permitting authorities.
