FilmTec™ TW30-4021


FilmTec™ TW30-4021 Reverse Osmosis (RO) Elements offer high quality water for small commercial systems. FilmTec TW30-4021 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.

FilmTec™ Brackish Water Reverse Osmosis 4" Elements can separate salts from water and are produced with an automated fabrication process that ensures precision, consistency, and reliability. They are ideal for use in medium-sized water treatment system that produce less than approximately 10 gpm (2300 L/h) of permeate. Our 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.
