Experiment demonstrates nanoscale structures can improve reverse osmosis seawater desalination – Qingdao, China

“With the assistance of the crown ether interlayer, the polyamide membrane obtains more nanoscale structures on the membrane surface and a nanoscale thickness, which are conducive to enhancing water performance, because the former increases the effective filtration area, while the latter greatly reduces the mass transfer resistance,” Jiang said.

“Moreover, nanoscale pores in the membrane can provide high-speed channels to promote water transport. The developed polyamide membrane demonstrates a superior water permeance over the pristine polyamide membrane while maintaining a comparable salt rejection.”

“The novelty of this work is the development crown ether [
