12 Ultraviolet Drinking Water Disinfection System

Description Design Features

Designed to treat flows up to 4.8 million gallons per day (15 MLD), the Sentinel
® Lamps 12 can effectively disinfect drinkingwater in small- to medium-sized treatment plants. The Sentinel • High intensity medium-pressure lamps
® 12 uses medium-pressure lamp technology to achievegreater than 4 log inactivation of Lamp Intensity Sensors Cryptosporidium and similarpathogens in drinking water. Medium-pressure lamp technology allows the Sentinel • DVGW-certified germicidal sensors (one per lamp)
® 12 to be compact with a small footprint. Thiscan provide a significant advantage to water treatment plants looking for a system that can be easily retrofitted into existing treatment systems. The Sentinel Cleaning System • Automatic Quickwipe
TM system
® 12 outperforms otheradvanced treatment technologies such as membranes and ozone at a fraction of the cost. The Sentinel Automated Operation and Control System
® 12 system featuresinclude independent, third-party-certified UV intensity sensors to assure accurate delivery of UV dose, an automatic quartz sleeve cleaning system, and a fully automated control system.The Sentinel • PLC-based operation and control Electromagnetic Ballast • Reliable time-proven design
® 12 was designed using advanced computationalfluid dynamics allowing for optimal lamp and baffle placement to ensure maximum reactor performance and operational efficiency. The Sentinel

Advantages

Low Cost: compared to other advanced treatment technologies such as ozone and membranes
® 12 has undergone third-party validationunder the U.S. EPA LT2 Enhanced Surface Water Treatment Rule guidelines.Calgon Carbon’s UV Technologies Division has hundreds of UV systems installed for treating a broad spectrum of contaminated groundwater, process water, wastewater, and drinking water. TheSentinel Compact Design: easy installation and retrofits for small- to medium-sized treatment plants Third Party Validated: in compliance with U.S. EPA’s LT2 Enhanced Surface Water Treatment Rule
® product line has one of the industry’s largest installedbases treating hundreds of millions of gallons of drinking water per day. Clean: no chemicals used for cleaning; produces no disinfection by-products Safe: automatic emergency shut down Reliable: robust long-life electromagnetic ballasts with superbvoltage tolerance Easily Installed: power cabinets may be located up to 500 feet(150 meters) from reactor
