Dow Water & Process Solutions



The DOW FILMTEC XLE-440 is an extra low energy, high productivity brackish water reverse osmosis element designed to deliver high quality water at low operating costs for municipal and industrial water applications. Its high active area design coupled with the highly productive XLE membrane makes DOW FILMTEC XLE-440 the lowest pressure RO element in the portfolio - resulting in lower energy costs. XLE-440 is perfectly suited for cold water feeds as the element's high productivity will deliver lower energy costs and/or higher permeate flow.

Used In:

  • Industrial water demineralization;
  • Production of municipal drinking water;
  • water reuse


  • High flux results in high yields and low energy costs;
  • High active area reduces number of elements required;
  • Filmtec performance and quality
