In the recent years，various new seawater reverse osmosis(SWRO)technologies like high recovery system design，internally staged design(ISD)concept，interlocking end-caps，split-partial second passes，UF/MF as pretreatment and advanced energy recovery devices have been reported.These are，altogether，dreams that finally have come true and we can already analyze the first results because，either in new plants or in existing ones，these new ideas are in operation.The purpose of this presentation is to prove the SWRO desalination affordable and to show field experiences from selected cases in which these new ideas are used and by having a look at the results try to conclude till which extend the theoretical advantages were justified or not.
