Limits of Energy Savings in Seawater Reverse Osmosis

This paper will explore the other practical issues that can arise when very high permeable SWRO membranes are used. One example is the flux imbalance that can occur in a pressure vessel. It is not unusual for the net driving pressure of the feed end to result in flux rates which differ by a factor of 10 times from the first to last element in the vessel. This and other design concerns will be discussed.
