UV advanced oxidation for contaminant destruction in impaired water

Potable Reuse and Drinking Water Remediation With UV Advanced Oxidation

Water resources are under stress due to increasing population, changing rainfall patterns, widespread pollution, and a variety of other factors. For this reason, water providers must strive to make the most of every available water source, even those that have been impacted by contamination. The TrojanUVPhox® uses the UV advanced oxidation process (UV AOP) to destroy a range of contaminants, even difficult-to-treat 1,4-dioxane and NDMA.

Protection Against a Range of Contaminants

Water treatment plants install the TrojanUVPhox to help treat and destroy a wide variety of harmful contaminants, including 1,4-dioxane, Nitrosamines (e.g., NDMA), industrial solvents, pesticides, Volatile Organic Compounds (VOCs), fuel and fuel additives, pharmaceuticals, personal care products and other wastewater-derived contaminants.

Unique Chamber Stacking Design

Vertically stackable and modular, the TrojanUVPhox allows for multiple chambers in series and the ability to expand without increasing footprint. It is available in multiple configurations with various numbers of lamps per chamber to handle virtually any flow rate.

UV AOP Eliminates Residuals

UV AOP has the advantage of being a destructive technology that breaks down a variety of contaminants into their safe, elemental components. Other treatment technologies merely transfer the contaminant from one phase to another (e.g., air stripping: from water to air) resulting in a potentially hazardous, contaminant-laden residual that requires further treatment or disposal.

User-friendly Controls Optimize Operation

The oxidant delivery system is part of the TrojanUVPhox solution. It integrates with the UV controls to ensure smooth operation with minimal operator involvement. The UV controller can also use system inputs to determine optimal power settings for lamps and automatically turn lamps on/off or adjust lamp power. This conserves energy and extends lamp life, all while ensuring your required dose is being met.

Designed for Easy Maintenance

Lamps are easily replaced without having to de-pressurize or drain the chamber. All internal components can be accessed from the ends of the chamber and, as a safety feature, the chamber automatically deactivates if the end cap is removed, protecting operators from high voltage components.
