[영국] 런던 히드로공항, GE의 산업용 인터넷 업그레이드로 물 사용량 삭감 

영국에서 가장 큰 공항은 GE의 선진 수처리 솔루션을 사용해 매년 1억3천만 리터 이상의 물을 절약하고 있다.

런던 히드로공항에서 네번째 터미널을 가로지르는 39 냉각탑은 GE의 부식방지제, 냉각 및 화학 처리기술로 처리됐다. GE에 따르면 12개월 후에 공항은 총 현장 물사용의 5% 상당과 비용 면에서 31만 달러를 절약했다.

이전에 39 냉각탑은 오직 두 번의 사이클로 냉각탑이 제한되었던 오존으로 다뤄졌다.

GE의 수처리제를 사용한 후 히드로 공항은 물 효율성의 상당한 증가와 깨끗한 물을 발생시키는 냉각탑 사이클을 2에서 5로 증가시킴으로써 보충수 요구를 줄일 수 있었다.  

공항의 냉각탑은 실시간으로 모니터링되고 데이터는 GE의 시스템으로 분석됐다.

LONDON HEATHROW AIRPORT CUTS WATER USAGE AFTER INDUSTRIAL INTERNET UPGRADE FROM GE

LONDON, UK - The largest airport in the UK saved more than 130 million liters of water annually using GE’s advanced water treatment solutions.

Thirty-nine cooling towers across four terminals at London’s Heathrow Airport were treated with GE's corrosion inhibitor, cooling and chemical treatment technologies.

 
After 12 months, the airport saved the equivalent of 5% of total site water usage and $310,000 in costs, according to GE.

Previously, the 39 cooling towers were treated with ozone, which restricted the cooling towers to only two cycles.

After using GE’s water treatment chemicals Heathrow Airport was able to reduce make-up water demand by increasing cooling tower cycles from two to five, which led to a substantial increase in water efficiency and clean water.

The airport’s cooling towers were monitored in real time, and the data was analysed with GE’s systems.

Using the power of the Industrial Internet, GE’s InSight and TrueSense technologies enabled the precise dosing of chemicals in the right quantity and allowed for continuous monitoring to ensure system performance, cost optimization and improved efficiency.

“With more than 75 million passengers per year, 80 airlines, over 76,000 employees and an average of approximately 1,300 flights per day, Heathrow Airport is one of the busiest airports in Europe, and we consume a significant volume of water,” said Chris Allen, Heathrow Airport Limited.

“It is crucial we work with partners to reduce our environmental impact and are pleased that the GE technology has allowed us to exceed our environmental and industrial goals while meeting our high operational demands. We have been able to reduce our water usage and costs and improve efficiency.”

Amy Ericson, global leader, chemical and monitoring solutions?water and process technologies for GE Power, said: “Airports use a large amount of water and energy. By reducing corrosion and increasing the efficiency of the cooling towers across four terminals, Heathrow Airport saved over 130 million liters of water a year.”
