Dissolved air flotation systems helps increase United Arab Emirates potable water supply

A Xylem dissolved air flotation pretreatment system will be provided to Abu Dhabi Emirate to help ensure a steady potable water supply.

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.
