국제적인 공학기술과 프로젝트 경영 자문 회사인 Royal HaskoningDHV는 친환경적이고 비용 절감에 효과적인 메탄 여과 기술을 개발했다.

물 공급 회사 Vitens는 세계 최초로 네덜란드 식수 생산 공장에 진공 탈가스 시스템을 설치했고, 추출된 가스는 깨끗한 에너지원으로 사용이 쉽다고 밝혔다.

최근까지 지하수는 Vitnes의 전체 온실 효과를 내는 이산화탄소의 30%를 차지했지만, 새로운 탈가스 공장은 온실 효과를 내는 이산화탄소의 많은 양을 감소 시켰다.

A new method that filters methane from water in a cost-effective and environmentally-friendly way has recently been developed by Royal HaskoningDHV, an international engineering and project management consultancy.

Water supply company Vitens was the first in the world to install this vacuum degassing system in its drinking water production plant in Spannenburg, a neighborhood in northern Netherlands. Once extracted, the gas is easy to use as a clean source of energy.

Wastewater and drinking water often contain high concentrations of greenhouse methane gas, especially in peat lands like the Spannenburg area. Until recently, this groundwater was responsible for 30 percent of Vitens' total CO2 footprint. The new degassing plant, however, significantly reduces this footprint in a single stroke.

"Our calculations show that we will save almost €500,000 (US $691,135) per year with this plant due to the 'free' energy it produces," said Oege Hoekstra, project manager at Vitens. "These earnings are primarily due to the use of this gas as an energy source." Further, Vitens has decided to burn the gas to produce electricity. It is also possible to refine the gas into a natural gas grade or liquid gas for use in cars.

Royal HaskoningDHV developed the business case for Vitens, as well as the plant' design and supported the water company in constructing the plant.
