Severn Trent Services Receives Environmental Business Journal Award for Products That "Advance the State of the Art in Water and Wastewater Treatment"


FORT WASHINGTON, Pa. - February 16, 2010 - For the second consecutive year, Severn Trent Services received the Environmental Business Journal's (EBJ) Technology Merit Award in the Water/Wastewater category as part of the Journal's annual EBJ Business Achievement Awards. According to the EBJ, the company was recognized "for the introduction of several new products that advance the state of the art in water and wastewater treatment." The products include the MicroDynamics® Closed Vessel Microwave Ultraviolet (UV) disinfection system; the Capital Controls® Series 70CV3000 Chloromatic(TM) Intelligent Gas Flow Control Valve and the Severn Trent De Nora OMNIPURE(TM) Series 55 and MARINER OMNIPURE® Series M55 marine sanitation systems. The 2009 award will be presented by EBJ, a leading business newsletter for the environmental industry, at the 2010 Environmental Industry Summit, March 3-5, 2010, in San Diego.

The annual EBJ Business Achievement Awards program recognizes firms for their strong financial performance and growth as well as for specific projects or other business achievements, which are significant in the advancement of the environmental industry.

Severn Trent Services' MicroDynamics closed vessel microwave powered UV disinfection system features an innovative UV design for water applications that uses microwave energy to energize electrodeless lamps. The system 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.

The company's new Capital Controls Series 70CV3000 Chloromatic intelligent gas flow control valve is a wall-mounted system designed for automatic control of chemical feed in water or wastewater applications. The Series 70CV3000 is an integrated, microprocessor-based controller with control valve that responds to multiple process signals from a water flow transmitter or chlorine residual analyzer. The system eliminates the need for continuous operator monitoring and manual adjustment of the gas feed rate resulting from changes in flow or residual levels. The automation of the chemical feed process yields a reduction in gas consumption for water and wastewater utilities, since manual system feed rates are based on peak process conditions.

Severn Trent De Nora's OMNIPURE Series 55 and MARINER OMNIPURE Series M55 marine sanitation systems are designed to meet stringent new MEPC.159(55) effluent standards and performance tests for sewage treatment plants across a variety of offshore and marine installations. These standards, adopted by the International Maritime Organization's (IMO) Marine Environmental Protection Committee, apply to all sewage treatment systems installed on board on or after January 1, 2010. Both products incorporate a highly effective electrolytic technology that produces a sodium hypochlorite disinfection solution from seawater in the presence of sewage to effectively treat all sewage. The systems have received Bureau Veritas Process Type approval for IMO Resolution MEPC.159(55).
