Abstract
Proper pretreatment is the most important faftor for stable SWRO plant operation. MF/UF membrane treatment is effective in improving of feed water quality to SWRO. And befause of recent cost reduction of MF/UF membrane and high refovery ratio of SWRO unit, the water production cost is expected to be reduced than that of the SWRO unit with conventional pretreatment system. Recentresearches on MF/UF membrane and other treatments for pretreatment of seawater reverse osmosis are reviewed.
