TrojanUVFit UV Disinfection System

Overview

The TrojanUVFit UV Disinfection System is a compact, closed-vessel ultraviolet (UV-C) water disinfection platform engineered for municipal and industrial wastewater reuse applications. It operates on the principle of germicidal irradiation—exposing flowing water to 254 nm UV-C light emitted by low-pressure high-output (LPHO) or medium-pressure (MP) UV lamps housed within stainless steel reaction chambers. This non-chemical process inactivates bacteria, viruses, protozoa (including Cryptosporidium and Giardia), and chlorine-resistant pathogens by disrupting their DNA/RNA replication capacity. Unlike chemical disinfectants, UV treatment introduces no residual byproducts, avoids formation of trihalomethanes (THMs) or haloacetic acids (HAAs), and requires no handling or storage of hazardous reagents—making it compliant with evolving regulatory expectations for sustainable water reuse.

Key Features

• Modular, scalable design accommodating flow rates from 10 to 5,000 m³/h per skid—configured via parallel reactor banks or multi-lamp arrays;
• Optimized hydraulic profile with streamlined internal baffling and parabolic reflector geometry to minimize head loss (typically ≤0.3 m at design flow);
• Stainless steel 316L reactor vessels with electropolished interior surfaces for corrosion resistance and biofilm mitigation;
• Integrated UV intensity sensors (254 nm) with real-time dose calculation using validated actinometry-based algorithms;
• Automatic quartz sleeve cleaning system (mechanical wipers or ultrasonic) to maintain transmittance stability under variable water quality conditions;
• Self-calibrating UV transmittance (UVT) sensor interface compatible with inline UVT analyzers (e.g., Hach DR/3900 or similar) for dynamic dose adjustment;
• CE-marked and NSF/ANSI 55 Class A certified for tertiary effluent disinfection in accordance with EPA UV Guidance Manual (2006) and DVGW W294 (Germany).

Sample Compatibility & Compliance

The TrojanUVFit system is validated for use with secondary and tertiary treated wastewater having UVT ≥75% at 254 nm and turbidity ≤10 NTU. It supports compliance with multiple international discharge and reuse standards, including but not limited to: US EPA Guidelines for Water Reuse (2012), Ontario Regulation 170/03 (Canada), Australian Guidelines for Water Recycling (2006), and ISO 10500:2016 (UV disinfection performance testing). All control logic and data logging meet GLP/GMP-aligned audit trail requirements, with optional 21 CFR Part 11-compliant software modules available for regulated pharmaceutical or food-processing facilities.

Software & Data Management

The integrated UV Controller (UC-2000 series) provides local HMI operation and Ethernet/IP connectivity for SCADA integration. Firmware supports Modbus TCP, BACnet MS/TP, and OPC UA protocols. Historical UV dose, lamp status, UVT input, and maintenance logs are stored onboard for ≥18 months and exportable in CSV or XML format. Remote diagnostics—including lamp aging prediction, quartz fouling rate estimation, and predictive maintenance alerts—are enabled via Trojan’s cloud-based UV Connect™ platform (optional subscription). Audit trails include user login events, parameter changes, and alarm acknowledgments with timestamps and operator IDs—fully traceable for regulatory inspections.

Applications

• Municipal wastewater reclamation for irrigation, industrial cooling, and groundwater recharge;
• Industrial process water disinfection in food & beverage, pharmaceutical, and semiconductor manufacturing;
• Effluent polishing prior to surface water discharge where chlorine residual restrictions apply;
• Decentralized treatment systems serving commercial campuses, hospitals, and remote communities;
• Emergency response units requiring rapid-deployment, trailer-mounted UV disinfection skids.

FAQ

What is the required UV dose for Cryptosporidium inactivation?

A minimum fluence of 10–12 mJ/cm² is recommended per US EPA guidance; TrojanUVFit achieves this across its full flow range when operated within specified UVT and lamp output parameters.
Can TrojanUVFit be retrofitted into existing concrete channel installations?

No—it is a closed-pipe, pressurized system designed for integration into piped infrastructure; open-channel UV systems (e.g., TrojanUVSigna) are used for gravity-fed channels.
Does the system require pre-filtration?

Yes—particulate removal to ≤10 µm (via dual-media or membrane filtration) is essential to prevent shadowing and ensure consistent microbial inactivation efficacy.
How often must UV lamps be replaced?

Lamp replacement intervals are typically 9,000–12,000 operating hours depending on lamp type (LPHO vs. MP) and thermal management; the controller tracks cumulative exposure and triggers maintenance alerts accordingly.
Is third-party validation data available for this model?

Yes—full-scale bioassay validation reports per USEPA UV Disinfection Guidance Manual protocols are available upon request from Trojan Technical Support or authorized distributors.
