FILMTEC™ XLE PRO-4040 Brackish Water Reverse Osmosis Membrane Element
DUPONT FILMTEC™ XLE PRO-4040 Elements offer better system performance and economics for small commercial systems by operating at very low applied pressure. FILMTEC XLE PRO-4040 elements are tape-wrapped. In addition to high quality water and low energy costs, FILMTEC membranes also deliver savings by providing long lasting and reliable performance. For added convenience, the elements are available in a dry state for rapid start-up.
FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.
DOW and Dupont merged and DOW FilmTec membranes are now sold as DUPONT FilmTec. FilmTec XLE-4040 membrane element has been discontinued by the manufacturer. XLE PRO-4040 is the direct replacement.
