에너지 효율성과 소규모 담수화 시스템 전문업체인 Spectra Watemarkers사가 영구적인 태양열, 풍력 담수화 플랜트를 마셜제도 킬리(Kili)의 멀리 떨어진 산호섬에 제공했다. 이 플랜트는 현재 운영 중이며, 지역의 두 번째 동종 시설로 자리잡았다.

Moana Marine LLC사의 Tom Vance는 두 스펙트라 LB-2800 역삼투(RO) 담수화 시스템을 설치했는데, 이는 해수를 하루 5천600 갤런의 깨끗한 식수로 변환하는 규모의 시스템이다.

시설을 설치하기 전 1천200명의 킬리 거주자들은 가뭄뿐만 아니라 오염된 지하수 때문에 고통받아 왔다.

 

 

 

Spectra Watemarkers, a specialist in energy-efficient, small-scale desalination systems, has provided a permanent solar and wind-powered water desalination plant on the remote atoll of Kili in the Marshall Islands, which is now operational and serves as the region's second facility of its kind.

 

Tom Vance of Moana Marine LLC installed the two Spectra LB-2800 reverse osmosis (RO) desalination systems, which convert seawater into over 5,600 gallons per day (GPD) of clean, fresh, EPA-approved drinking water. Before the installation, Kili's 1,200 residents suffered not only from drought but from polluted groundwater, which had to be boiled before drinking.

 

A typical desalinating plant of this size would be powered by a diesel generator. Because of the energy efficiency of the desalination systems, the whole plant can be powered by wind and solar power, saving thousands per year in fuel costs. Moreover, with increasingly expensive fuel and unreliable supplies due to seasonal rough seas, alternative energy-powered systems can assure a consistent, affordable water supply.

 

Spectra uses proprietary energy-recovery pumps. The two installations stand as a model for drought preparedness and safe, sustainable water production in the Pacific Island region. Earlier this year, a similar plant was installed on the atoll of Utrik, 400 miles to the north.
