칠레 공화국의 채광산업이 새로운 담수화 시설 프로젝트와 함께 발전하고 있다는 소식이다. 압력 순환 및 산업 용수 유체에서 재활용 가능한 에너지를 생산하는 기업인 Energy Recovery Inc.는 스페인 물 기업 ACCIONA Agua가 자사의 프리미엄 PX 기술을 선택하여 남미 국가들에서 진행되는 Minera CAP 담수화 시설 확대 프로젝트를 진행한다고 발표하였다.

올해 초, ACCIONA는 CAP Group에 의해 칠레 아타카마(Atacama) 제 3 지역, 코피아포(Copiapo)에서 진행되는 Minero Cerro Negro Norte Project의 수도 도관 및 집중 작업을 담당하기로 선택되었다. 이 담수화 시설의 성능은 초기 하루 21830톤이었고 내년에 걸쳐 하루 39310톤의 성능으로 개선, 발전될 예정이다.

SAN LEANDRO, CA, July 16, 2013 -- The country of Chile's mining industry has been enhanced with a new desalination project. Energy Recovery Inc. (NASDAQ: ERII), the leader in harnessing reusable energy from industrial fluid flows and pressure cycles, announced that Spanish water company, ACCIONA Agua, has selected the company's premium PX® technology for the Minera CAP expansion desalination project in the South American country.

Earlier this year, ACCIONA was chosen by the Compania Minera del Pacifico (CAP Group) to carry out water conduits and concentrate project works related to the Minero Cerro Negro Norte Project located in the Copiapo Valley, in Chile's Atacama Region III. The desalination operation will have an initial capacity of 21,830m3/day, with a potential of 39,310 m3/day within the next year.

This is welcoming news to Chile's mining industry, which contributes to 50 percent of gross domestic product (GDP) for the northern Atacama region and 20 percent of the country's GDP. This area is referred to as the "desalination frontline" as the agricultural and mining industries compete with each other for current fresh water production.

Mining is one of the main economic activities in Atacama; mined copper exports alone stand for more than one third of government income. In many northern parts of Chile, water extraction is more than the regular rate of replenishment, which is not sustainable long term. As a result, this puts further risks on the entire aquifer if they reach the limits of seawater intrusion. Fortunately, the Chilean government has a very large "aquifer" to the west, the Pacific Ocean, which makes desalination a very simple and real solution to water scarcity problems.

"Chile is on the forefront of a major desalination boom and we are proud to help contribute to the country's economic development in this regard," remarks Tom Rooney, CEO and President of Energy Recovery. "We look forward to working with ACCIONA and the Chilean government in the years to come and helping our partners attain their high environmental and quality objectives."

One of ACCIONA'S goals is to save energy with Energy Recovery's PX technology. In phase I of the project, the water company will be saving 19 million kWh/ year or $USD 1.9 million and reducing the plant's CO² emissions by over 11,000 tons. The potential additional savings for Phase II would be 15 million kWh/year or $USD 1.5 million and close to 9,000 tons of CO² per year.

Energy Recovery technology is well known in Chile and is being used in numerous desalination plants throughout the country. The Company is working with Spanish water companies ACCIONA Agua, Valoriza, Aqualia and Cadagua, and is in early stage discussions with Israeli, American and Korean companies around the world who view Chile as a strong future market. Many of the legacy plants are still using Pelton technology because electricity costs were lower at the time of design. Now that energy costs have risen significantly, the PX technology is an attractive choice for upgrade in the near future as the payback for investment is within months.
