Current Status and Future Trend of Dominant Commercial Reverse Osmosis Membranes
Since 2000, seawater reverse osmosis method has been a dominant desalination technology against the distillation method in the global market. The large project called “Mega-SWRO” (half mega-ton per day and larger) plant in the Middle East is quite popular making full use of the combination with sola...
