액체 염소의 벌크 저장으로 인한 위험을 줄이려는 노력의 일환으로 잉글랜드 체스터의 Huntington Water Treatment Works가 Severn Trent Services사의 선진 현지 치아염소산염(hypochlorite) 생성 시스템을 채택했다. 헌팅턴 수처리 회사는 유럽에서 가장 큰 식용 염수 자동 염소처리 플랜트이다.

Severn Trent는 여섯 개의 ClorTec HCT-1500 장치를 설치했으며, 각각의 장치는 하루 최대 680㎏의 염소에 해당되는 생산량을 보유한다.

 

 

 

In an effort to reduce risk from bulk storage of liquid chlorine, the Huntington Water Treatment Works in Chester, England -- Europe's largest potable water brine electrochlorination plant -- has received an advanced on-site hypochlorite generating system from Severn Trent Services, a global supplier of water and wastewater solutions.

 

Severn Trent installed six ClorTec® HCT-1500 units, each with a production capability of up to 680 kg/day of chlorine equivalent. Overall, the units have the potential to produce 4,080 kg/day of chlorine equivalent and are able to produce the 3,360-kg maximum chlorine demand at Huntington in an operating period of 20 hours.

 

Originally, the ￡35-million ($39.1-million) upgrade, part of a ￡3.6-billion ($4-billion) investment by United Utilities across North West England, called for the construction of a new facility to store drums of liquid chlorine on site. However, the project team identified an alternative process that would eliminate the need to store hazardous liquid chlorine, reducing the risk to operators and demonstrate best practices in health and safety.

 

Generating sodium hypochlorite on site is a simple and straightforward process. The ClorTec system operates by feeding a mix of softened water and brine at a 3-percent solution through electrolytic cells. A low-voltage DC current is applied and a 0.8-percent sodium hypochlorite solution is produced.
