스웨덴이 세계 물 시장의 도전적인 과제들을 적극적으로 해결하는 세계적 물 기술 회사인 Xylem으로부터 자국 내 최대 자외선 살균 프로젝트를 지원받아 UV 음용수 처리 솔루션 플랜트를 건설할 것으로 발표했다. Xylem은 16개 도심 지역을 걸쳐 90만 명의 인구에 깨끗하고 처리된 음용수를 공급하는 프로젝트 사업을 이 스칸디나비아 국가로부터 수주에 하는데 성공했다.

Xylem은 남부 스웨덴 Scaniawl역에 위치한 Sydvatten AB 수처리 시설을 개선, 업그레이드 하기위해 WEDECO K 시리즈 자외선 살균 시스템 4기를 제공하기로 하였다. 더 나아가 Xylem의 WEDECO K143 UV 시스템은 향후 플랜트 확장에도 적합하고 대용량의 물을 가장 효율적으로 처리할 수 있는 능력을 보유한데다 유연하고 혁신적인 디자인, 낮은 유지 비용, 낮은 환경 영향 평가 등의 장점을 지니고 있어 선택된 것으로 알려졌다.

SCHAFFHAUSEN, SWITZERLAND, July 17, 2013 -- Sweden will soon receive ultraviolet (UV) drinking water treatment solutions for its largest UV disinfection project ever. Xylem, (NYSE: XYL), a leading global water technology company focused on addressing the world's most challenging water issues, has won a contract to provide the Scandinavian country with the progam that will help deliver clean, treated drinking water to 900,000 people across 16 municipalities.

Xylem will provide four WEDECO K- Series UV disinfection systems, to upgrade the Sydvatten AB Waterworks in the Scania (Skane) region in southern Sweden. Further, Xylem's WEDECO K143 UV systems were chosen for their flexible and innovative design, low lifecycle costs, negligible environmental impact, and ability to handle large volumes of water in the most efficient manner possible, while catering to potential future plant expansion. 

Harnessing the power of UV disinfection eliminates the risk of harmful by-product formation, such as trihalomethanes (THMs) which can be caused by chlorination. By changing the DNA of waterborne pathogens, UV prevents further cell division, rendering more than 99.99 percent of all pathogens harmless in seconds.

The WEDECO K143 systems each feature 13 rows of 12 UV lamps and will treat a total of 4,300 cubic meters of water per hour. The vessels were designed with installation and future expansion in mind by having the various sections bolted rather than welded together. This met the requirement of having no section longer than 2.5 meters and allows the possibility of adding another section of lamp rows at a later date. In this way the solution is future-proofed to cater for increased demand as the population grows.

Xylem is working on this project together with their Swedish Representative -- Christian Berner AB -- which led the tender process. Xylem's WEDECO UV Systems will complement existing traditional treatment methods to eliminate bacteria, viruses and parasites. 

The Sydvatten AB Waterworks drinking water treatment plant has been in operation since 1966. The facility will have the capacity to handle a potential 25 percent increase in water volume to support future population growth.
