Severn Trent Services Introduces MicroDynamics Closed Vessel Microwave UV System

Economic, reliable, safe disinfection with Cryptosporidium certification for municipal and industrial applications

FORT WASHINGTON, Pa. - March 31, 2009 - Severn Trent Services has introduced the new MicroDynamics® Closed Vessel Microwave Ultraviolet (UV) disinfection system. The innovative UV design is suitable for use across a range of municipal and industrial applications, including municipal water and wastewater treatment, swimming pool disinfection, cooling tower water disinfection, industrial water treatment and Cryptosporidium treatment.

The system uses microwave energy to energize the bulbs and generate consistent-strength UV disinfection. MicroDynamics microwave UV offers extended bulb life and reliability, operating cost savings and health and safety benefits for employees on site due to its unique design. The bulb replacement and maintenance costs of MicroDynamics systems can be as little as half of competing UV technologies, primarily driven by the unique microwave powered electrodeless lamps. Each system comes with a three-year bulb life warranty.

MicroDynamics microwave UV electrodeless lamps operate at similar pressures and temperatures to traditional low pressure lamps. A single MicroDynamics CV02 system can treat flow rates up to 6,000 m3/day (1200 GPM). Multiple vessels can be arranged in series or parallel to increase the flow rate through the system.

The MicroDynamics design ensures simplified and safer maintenance compared to other systems. In addition, the systems are suitable for high-pressure design operations up to 10 bar (145 psi).

The MicroDynamics CV02 system is ideal to treat Cryptosporidium and has been validated for a log 4 Cryptosporidium credit by HydroQual Environmental Engineers and Scientists, P.C. per the latest United States Environmental Protection Agency UV Disinfection Guidance Manual LT2 regulations.
