Disinfecting Filtered Effluent

Depending on site and design conditions, wastewater treatment plants producing filtered effluent sometimes prefer a disinfection solution using in-pipe (also called closed-vessel) UV chambers. The TrojanUVFit® offers an effective, compact, and energy-efficient solution for non-potable reuse with a streamlined hydraulic profile that won’t break head in the treatment process. The system is available in multiple configurations to treat a wide range of flow rates, up to 7 MGD per chamber.

Applications

• Non-potable Reuse

Regulatory-endorsed Bioassay Validation

System sizing is based on actual dose delivery verified through bioassay validation. Real-world, field-tested performance data eliminates sizing assumptions and risks associated with theoretical dose calculations, offering peace of mind and improved public and environmental safety. For reuse applications in California, the California Department of Public Health has approved the 32AL50 model for Title 22 reuse applications and the remaining TrojanUVFit models are pending approvals. All validation testing was done in accordance with the NWRI/AWWARF UV Guidelines.

Compact Design and Installation Flexibility

The compact chamber footprint simplifies indoor retrofit installations and can also be installed in parallel or in series, making it simple to incorporate redundancy or future expansion needs. UV lamps and sleeves are fully serviceable from the chamber end cap, allowing the system to be installed against walls, other equipment or piping.

Robust Sleeve Cleaning System

The sleeve cleaning system minimizes fouling of quartz sleeves, ensuring the maximum UV output is available for disinfection. The system works automatically at preset intervals without operator involvement and without interrupting disinfection.

Reliable Performance and Easy Maintenance

UV lamps, quartz sleeves, lamp drivers, sensors and the sleeve cleaning system have been proven reliable and are operating in hundreds of installations. Internal components are all easily accessed from the end cap which, when removed, automatically deactivates lamps for operator safety. Routine procedures, such as lamp change-outs are simple and require minimal time.
