DOW FILMTEC™ TW30-2514 Brackish Water Reverse Osmosis Membrane Element
DOW FILMTEC TW30-2514 Elements produce high quality water for small commercial systems. DOW FILMTEC TW30-2514 elements are tape-wrapped. In addition to high quality water and low energy costs, DOW FILMTEC membranes also deliver savings by providing long lasting and reliable performance.
DOW FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. DOW 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 FILMTEC TW30-2514 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.
