英文摘要	Water scarcity is being recognized as one of the main threats that mankind is facing globally. Reverse osmosis membrane technology has developed as a promising technology to address this problem. This increase has been driven as materials are improved and costs dropped. This is especially relevant for Middle East countries (ME), where population is located in arid and semi-arid regions with limited rainfalls and a high degree of evaporation due to the high temperatures the region is exposed to. Therefore, getting a robust element that is able to offer a stable salt rejection even after multiple cleanings is of utmost importance to sustain the population and economic growth of the region. This paper aims at demonstrating the superior durability of FilmTec (TM) membranes compared to other manufacturers. This superior durability has been reported in a number of desalination plants where FilmTec (TM) membranes lifetime has exceeded more than 10 years, but a quantification and a reliable comparison of such superior durability compared to other manufacturers in a controlled environment has not been completed to date. In this paper, FilmTec (TM) SW30XLE elements are exposed together with equivalent commercially available membranes from other suppliers to a durability study to simulate long term operation and to determine the evolution of the membrane specifications over time. Particular focus is paid to the changes in salt rejection. Membrane durability plays a determining role in membrane replacement, which ultimately has a critical impact on the economics of any desalination plant. In this study, it was determined that after a number of cleanings, the salt passage increase over time of the membranes from other suppliers was close to 3.5 times larger than the value experienced by FilmTec (TM) membranes. More specifically, the salt passage increase experienced by FilmTec (TM) in the first study was 22%, while the membrane from another supplier showed a 73% increase; and in the second study, FilmTec (TM) had a salt passage increase of 43% while the membrane from the other manufacturer had a 140% salt passage increase. In a 100,000 m(3)/d desalination plant, this enhanced durability showed by FilmTec (TM) elements might represent a 5.5% cost of water decrease in the reverse osmosis stage, and total savings of 1.34 US cent/m(3) in the whole plant, which can be translated into savings of 488,000 USD/y.
