MIRFA IWPP, ABU DHABI, UAE.
The 52.5 MIGD (238,665 m3/d) Mirfa desalination plant in Abu
Dhabi represented a step-change for seawater reverse osmosis
(SWRO) in the Gulf region. The facility’s 30 MIGD (136,000 m3/d)
SWRO system showed the ability for membrane desalination to work
at scale in the most hostile of feedwater conditions in the Arabian
Gulf. Including a 1,600 MW power station in addition to desalination
capacity, at the time of commissioining the facility had the capacity to
generate 10% of Abu Dhabi’s power requirements, and represented
over 5% of the emirate’s water generation capacity.
