세계적 물 기술 기업인 Xylem 사가 개발한 용해성 공기중 부유 전처리 시스템(Dissolved Air Flotation System)이 UAE 동부 해안과 아부다비 에미레이트(Abu Dhabi Emirate)에 제공 및 설치되어 지역의 연속된 음용수 공급을 도울 예정이다.

오만 만(Gulf of Oman)에서 추출되는 원수는 적조(Red Tides)라고도 불리는 해로운 조류(Harmful Algal Blooms)의 영향을 많이 받는다. 이 불순한 조류 현상물질들은 다량의 독성 미세 물질들을 함유하고 있다. Xylem 사의 Leopold® Clari-DAF® 시스템은 깨끗하고 신선한 음용수의 생산을 보장하는 점에 있어 이전 담수화 시설에 비해 95% 이상 미세 물질 제거 능력이 뛰어난 것으로 드러났다.

WHITE PLAINS, NY, Aug. 8, 2013 -- A dissolved air flotation (DAF) pretreatment system from Xylem Inc., a global water technology company focused on addressing the world's most challenging water issues, will be provided to Abu Dhabi Emirate and the east coast of the United Arab Emirates (UAE) to help ensure an uninterrupted potable water supply to the region.

The source water in the Gulf of Oman is subject to harmful algal blooms (HABs), sometimes termed 'red tides,' which are aquatic blooms that contain large concentrations of potentially toxic microorganisms. Xylem's Leopold® Clari-DAF® system is more than 95 percent effective in removing these microorganisms prior to desalination ensuring the production of clean, fresh drinking water.

Xylem's Leopold Clari-DAF systems create millions of microbubbles that float the algae to the surface of the water where they are removed as floating sludge, usually by mechanical skimming. This technology is also extremely effective for the removal of free and emulsified oil which is very important for the protection of the downstream reverse osmosis system.

Xylem will develop the new pretreatment DAF system for the Fujairah 1 Independent Water and Power Plant (IWPP), which is owned by Emirates Sembcorp Water & Power Company (ESC), a joint venture between Abu Dhabi National Energy Company (TAQA), Sembcorp Industries and Abu Dhabi Water and Electricity Authority (ADWEA). The new system will have a capacity of 136,000 cubic meters per day (reverse osmosis output) to accommodate an anticipated 15 percent increase in the population by 2016. It will serve both the existing and new seawater reverse osmosis plants, which have a combined capacity of 306,760 cubic meters per day and will be one of the world's largest operating desalination plants.

"We are looking forward to working on this exciting project and helping to address the unique water challenges in this region of the Arabian Gulf," said Safwat Gergis, desalination pretreatment product manager for Xylem.
