| [Severn Trent] 중국 상수도 처리장에 염소처리 제공
상하수도 솔루션에 있어서 세계적인 선도자인 Severn Trent Services는 최근 중국 청두에 있는 청두 제7 상수도 처리장의 첫 시공 단계를 위해 동 회사의 완성된 염소처리시스템인 Capital Controls® 기술을 제공하기로 하는 계약에 서명했다.
도시화가 가속화됨에 따라 중국 남서부에 있는 이 도시의 물 수요는 현재 물 공급 능력의 상한선에 해당하는 한계에 이르렀다. 여름 중에 있을 최고 물 소비 기간이 오기 전에 청두에 공급될 물의 생산량을 늘리는 것은 이제 시급한 요구이다. 지난 20년 간 Severn Trent Services는 청두에 있는 모든 음용수 처리장의 약 95%에 염소처리 솔루션을 제공해 왔으며, 여기에는 이 도시의 제 2, 제 5 및 제 6 처리장도 포함되어 있다.
이 회사를 선택한 중요한 이유는 앞선 기술들을 가지고 규제기준들과 운영지침들을 만족시켰던 이 회사의 수많은 경험이었다.

Severn Trent to provide chlorination system to China tap water plant
SHANGHAI, China, April 18, 2013 -- Severn Trent Services, a leading global supplier of water and wastewater solutions, recently signed a contract to provide its Capital Controls® technology, a turnkey chlorination system, for the first construction phase of the Chengdu Seventh Tap Water Plant in Chengdu, China. With accelerating urbanization, the demand for water in the southwest China city has reached the upper limit of current water supply capacity. Increasing the water supply output for Chengdu before the peak water consumption period during the summer months is now an urgent requirement.
For the past 20 years, Severn Trent Services has provided chlorination solutions for approximately 95 percent of all potable water treatment plants in Chengdu, including the city's Second Plant, Fifth Plant and Sixth Plant. The company's extensive experience in meeting regulatory standards and operating guidelines with its leading technologies was a primary reason for its selection. The Capital Controls chlorination system will provide the Seventh Tap Water Plant, the largest chlorination system installation in Chengdu, with a cost-effective, end-to-end system.
The designed capacity of the plant's first-phase of construction is 500,000 tons/day. In order to address growing water consumption, the plant's long-term capacity will reach up to one million tons/day. Delivery of the project is scheduled for April 2013.
The chlorination system includes three Capital Controls Model 71V3000 liquid chlorine vaporizers. This is the only vaporizer in the industry with a Pressure Vessel Special Equipment Manufacturing License, approved by the People's Republic of China's General Administration of Quality Supervision, Inspection and Quarantine. The vaporizer meets stringent safety requirements, ensuring normal chlorine dosage of the plant and large-dose operation using break point chlorination under exceptional circumstances. The system also includes 13 Capital Controls Model FX4045 chlorinators, which implement opening and closing operations at the direction of the Model 1450 controller. The controller receives electrical input signals from the flow meter, and it automatically adjusts the control valve to maintain the residual chlorine level within the mandated range.
