Abstract: According to the present invention, it is possible to obtain a separation membrane element which has an element configuration having high fresh water production performance and high removal performance, has an improved membrane surface linear velocity whereby fouling due to hardly-soluble salts (scales) or organic matters is less likely to occur on the membrane surface particularly in high recovery ratio operation, and is excellent in fresh water production performance and removal performance over a long period of time.

Abstract: According to the present invention, even when a high recovery ratio operation is performed, the influence of concentration of ingredients to be separated in the feed fluid can be reduced, the concentration polarization can be prevented by increasing the turbulence effect on the membrane surface, and the fluid permeation performance and the separation performance of the separation membrane element can be maintained.
