The TrojanUVTelos ultraviolet disinfection system from TrojanUV combines Solo Lamp and Flow Integration (FIN) hydraulic-optimization technology in a low-lamp-count, low-energy and easy-to-maintain unit. Made to protect against bacteria, viruses and chlorine-resistant protozoa such as Cryptosporidium and Giardia, the closed-vessel system uses flow modifiers throughout to ensure the highest possible UV disinfection while reducing lamp count and energy requirements.

“FIN technology matches areas of high velocity with higher intensity UV light and low velocity with lower intensity UV light,” says Adam Festger, drinking-water market manager at TrojanUV. “That enables us to accomplish a very uniform dose distribution and high disinfection performance.”

The low-pressure output system is about 74 inches long, 15 inches wide and can be installed both vertically and horizontally. The UV chamber is made from 316L stainless steel and rated to 150 psi (232 psi available). A 1/2-inch drain port is included.

Designed for small communities, the system can treat up to approximately 1,000 gpm. The largest model has two UV lamps, while the smaller models have one UV lamp. The high-efficiency, high-output, low-pressure amalgam lamps have a lifespan of 15,000 hours.

“We believe there are a lot of small drinking-water systems that struggle with disinfection,” Festger says. “They may default to using the simplest disinfection methodology, which is typically chlorine. While effective for a disinfection residual, chlorination does not address Cryptosporidium, Giardia and other chlorine-resistant organisms. UV offers a chemical-free means to disinfect water, and it does so in a superior manner.

“Many small drinking-water facilities in the U.S. and Europe don’t disinfect at all,” he says. “The Telos is meant to provide a cost-effective, low-maintenance solution for those utilities.”

The disinfection system includes SCADA connection, remote online monitoring and enhanced regulatory reporting, as well as color touch-screen human machine interface. NEMA 4X (IP66) lamp drivers and controls are preassembled and mounted on the UV chamber, eliminating the need for a separate wall- or stand-mounted cabinet.

The optional sleeve- and sensor-wiping system helps reduce maintenance and optimize UV output by automatically cleaning the quartz sleeves and UV intensity sensor window. The cleaning system operates while online without interrupting disinfection and allows for cleaning at preset intervals using a motor-driven wiper assembly.

The system can be included in new construction or retrofit to existing plants. 888/220-6118; www.trojanuv.com.
