FilmTec BW30XHR PRO-400/34 RO Membrane

High Rejection 8″ Brackish Water Reverse Osmosis Membrane Element
FilmTec BW30XHR PRO-400/34 RO Membranes by DuPont are designed to significantly boost the output of reverse osmosis (RO) systems, while also improving the quality of the treated water and extending the lifespan of the membranes themselves.

  • Offers exceptional permeate quality
  • Delivers excellent silica, boron, nitrate, TOC, and ammonium rejection
  • Outstanding durability resulting in stable, long-term performance and sustainable water solutions
  • Enhanced fouling protection thanks to 34 mil feed spacer


DuPont FilmTec BW30XHR PRO-400 Brackish Water Reverse Osmosis 8 inch Elements can separate salts from water and are produced with an automated fabrication process that ensures precision, consistency, and reliability. BW30XHR PRO-400 Membranes are ideal for the use of large-scale industrial and municipal water treatment systems that produce greater than approximately 10 gpm (2300 L/h) of permeate. The FilmTec RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet today’s challenges for higher rejection using less energy and resisting foulants in challenging waters.
