미국 펜실베니아 소재 Severn Trent사는 도시하수 살균 및 물재이용 적용에 사용가능한 마이크로웨이브 작동되는 UV 시스템인 MicroDynamics Series OCS721 제품을 발표했다. 이 제품은 운전비용 감소, 램프수명 연장 및 적은 설치부지면적을 특징으로 하고 있으며 채널 내에 연이어서 설치가 가능하여 설계가 용이하며 관련 부품의 설치 작업량을 절감하는 효과를 주고 있다.
이 제품은 저압의 low-pressure, high-output 특성의 전극이 없는 램프를 가동하기 위하여 microwave를 이용하여 254nm의 UV광선을 발생시키며 주입량, log 제거율및 물의 요구 수질 모두 만족한 조건을 제공한다. 램프는 3년간 보장되며 자체 전극을 가지고 있지 않아 기존 UV 장치에서 발견되는 기계적 결함발생률을 줄일 수 있게 되었다. 한편 이 장치는 open-channel 설계 및 closed vessel 구조의 설계제작이 모두 가능한 제품이다.

Microwave UV system launched by Severn Trent
Pennsylvania-based Severn Trent Services has launched the MicroDynamics® Series OCS721, a new microwave-powered, open channel, ultraviolet (UV) system for municipal wastewater disinfection and water reuse applications.
The product offers greater operating cost savings, lower whole-life cost and long lamp-life in a smaller footprint. Modules can be placed side by side in channels for design flexibility and to reduce civil works requirements.
The system has been validated by National Water Research Institute for water reuse.
The MicroDynamics OCS721 system meets dose, log reduction and water quality requirements for a variety of applications. The technology uses microwaves to energize low-pressure, high-output, electrodeless lamps to generate a UVC output of 254 nm, an optimal wave length for bacterial disinfection. The lamps also include a three-year warranty.
The system features MicroPace™ ― a flow pacing technology that can match UV dose.
"This unique feature allows for reliable and accurate control of operating conditions in real time to save energy," said Stan Shmia, UV product manager at Severn Trent Services. "MicroDynamics OCS721 represents a significant advancement in UV lamp technology. Costly lamp maintenance and replacement are now things of the past."
Microwave-powered UV lamps do not have electrodes and remove the major failure mechanism found in traditional UV lamp technology. Severn Trent Services offers systems in open-channel designs for the UV disinfection of wastewater or closed vessel designs as an ideal solution for both wastewater and drinking water treatment.
