Reverse osmosis in Industry
•Reverse osmosis membranes are used for 3 specific applications:− To remove salts: from Brackish water and seawater− To remove organics: from surface water, waste
water and industrial reuse− To produce demineralised water

Conclusion: Desalination and reuse – a complementary solutioncomplementary solution
•D li ti d b th l •Desalination and reuse are both commonly used in industry.
•They are complementary solutions to increase water supply.
•Integrated resource management standpoint−Desalination appears as a true source of Desalination appears as a true source of
« additional freshwater », rainfall independent that can be used for every independent that can be used for every purpose

Conclusion: Desalination and reuse – a complementary solutioncomplementary solution
−Reuse is a « second stage» in a cascade of gwater uses; it does not create additional freshwater and is using treatable source of gwaste water.
•Geographic standpointGeographic standpoint−Waste water is available everywhere in urban areas; Industrial waste water is urban areas; Industrial waste water is available at the production siteS li t i il bl tl i t l −Saline water is available mostly in costal areas -> Water transfer cost (investment
