About this technology
A spiral-wound thin-film composite element: feed flows along the membrane under pressure, permeate passes through, and the concentrate carries the rejected salts away. Our RO and nanofiltration element guide covers selection, operating limits and the questions that decide which grade fits a duty.

What warranty applies?
None. DuPont's Product Data Sheets state "NO WARRANTIES ARE GIVEN" and expressly exclude
merchantability and fitness for a particular purpose, because performance depends on feed water and
operating conditions they do not control. Full statement.
