DOW FilmTec Membrane Elements

DuPont FILMTEC™  BW30 PRO-4040 Brackish Water Reverse Osmosis Membrane Element (Direct Replacement for DOW FilmTec BW30-4040 & LC HR-4040 )

Fiberglassed Large Commercial Elements for Challenging Water Conditions

DuPont FILMTEC BW30 PRO-4040 (formerly DOW FIlmtec BW30-4040) membrane elements are an industry standard for reliable operation and production of high quality water in light industrial and drinking water applications. This element features the fouling resistance membrane chemistry (made in USA) and thicker feed spacer to lessen the impact of fouling in harsh water conditions as well as a fiberglassed shell, which is recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops. For the most effective cleaning, the element may be cleaned over a wide pH range (pH 1 – 13).


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.

DOW FilmTec vs DuPont FilmTec & Membrane Compatibility Notes:

  • DowDuPont merger was completed in 2017 and FilmTec Corporation was moved to DuPont. DOW Water Solutions and DOW FilmTec Membranes are now DuPont Water Solutions and DuPont FilmTec Membranes.

  • FilmTecMembranes BW30-4040 and LC HR-4040 were discontinued by DuPont in 2022 and are replaced by FilmTec BW30 PRO-4040 which is the direct replacement with superior performance specifications.
