The Duron UV disinfection system is installed with a vertical inclination at an angle of 45 degrees, in an open channel, equipped with an integrated compact automatic lifting device and powerful energy-efficient Ecoray lamps. Designed for installation in new wastewater treatment plants or retrofitting existing ones, the Duron system is adapted for contact with chlorine and provides ideal disinfection for medium to large wastewater treatment plants.
The improved Ecoray 600 W lamps together with the new lamp orientation reduce the number of lamps required by more than 50% compared to conventional low pressure amalgam UV lamps. Energy is saved by automatically reducing the brightness of the lamps according to the required dosage. The Ecoray 600 W lamp is also more energy efficient than more powerful lamps, further reducing energy costs.
The reduced number of lamps is balanced by the lamp's 1.4 meter length, which is easy to handle. In addition, the requirement for a smaller channel depth reduces construction costs. At the same time, a small footprint is maintained due to the compact inclined design.
The layout options allow the system to be designed to easily adapt to higher flow rates or new regulations in the future by adding additional UV units.
The Duron UV system ensures optimal radiation dosage and therefore energy consumption. OptiDose, a real-time sensor-based dose control, monitors operating conditions including flow, UV transmittance (UVT) and UV intensity. Using proven control logic, OptiDose adjusts power consumption to the minimum necessary to meet the dosing requirements for each competitive situation.
The Ecoray lamp and Xylem ballast technology provide a higher relative UV output than conventional low-pressure amalgam UV lamps when operating in dimming mode.
The design can be fine-tuned to suit water quality, operating conditions and discharge requirements, and ensure that the system is sized optimally.
Duron UV system is easy to maintain. Lamps can be replaced as long as the modules remain in the channel. Dry-top access to the UV lamp and a compact integrated lifting mechanism ensure maximum safety and ergonomic maintenance. Each module can be lifted individually to a service-friendly height. Cleaning the quartz lamp sleeve is simple and safe, even in waters with high pollution concentrations.
Although some actions, such as cleaning the glass or replacing the sensor, require lifting the module, a unique automatic mechanism lifts this individual module while other groups of modules remain in operation, ensuring continuous water treatment even during maintenance. Operator access is quick and easy, requiring no external lifting equipment or additional platform.
For seasonal maintenance, the modules can be lifted out of the channel and remain in the raised position.
Duron's electrical components are easily accessible. Ballast cards are separated from the UV lamp modules for ease of maintenance and stability of operation. Cabinets are adapted for both indoor and outdoor applications.
