[호주] AGL, frack water 처리를 위한 담수화 플랜트 설치


호주의 재생 에너지 회사인 AGL이 Gloucester coal-seam gas 프로젝트의 수열파쇄 공정에서 생산되는 물을 처리하기 위한 담수화 플랜트를 설치한다고 밝혔다.

AGL의 수문지질학 관리자인 John Ross는 " 담수화된 물은 매우 효율적이게 사용될 것이며 담수를 관개를 위해 사용하는 전략계획을 제안했다. 또한, 우리는 지역의 세 가지 부문에서 물을 사용할 수 있는 방법을 모색하고 있다"고 말했다.

AGL는 Gloucester Gas Project의 부문으로써 지역의 110개 석탄 가스 정에 대해 조건부 승인을 가지고 있다. 또한, 제안된 Gloucester plant의 세부 사항에는 Gloucester gas project의 첫 단계를 위한 추출수의 관리 전략을 포함하고 있다.

Australian renewable energy firm AGL plans to install a 2 Ml/d desalination plant to treat water produced during hydraulic fracturing (fracking) at its Gloucester coal-seam gas project.

AGL's manager of hydrogeology, John Ross, said the desalinated water could have "so many" beneficial uses. "Our draft strategy proposes that the freshwater can be used for irrigation, however, we are looking at ways to make the water available to third parties in the local area," he said.

Options under consideration, he said, included  aquaculture, irrigating green areas in Gloucester and forestry projects.

Residual salt could be crystallised and disposed of at a licensed facility, he said but added, the company was still exploring options for its disposal.

AGL has conditional approval to establish 110 coal-seam gas wells in the region as part of its Gloucester Gas Project. Details of the proposed Gloucester plant are included in a draft extracted water management strategy for Stage One of the Gloucester gas project.

The project been through a full environmental assessment and received approval from the New South Wales Planning Assessment Commission, which was upheld by the Land and Environment Court.

In developing the draft strategy, AGL said it took into account community feedback concerning the management of produced and flow back water and options suggested by Gloucester Shire Council.
