FILMTEC BW30-4040

FILMTEC™ brackish water reverse osmosis membrane elements provide consistent, outstanding system performance in light industrial applications.

  • FILMTEC BW30-4040 is the industry standard for reliable operation and production of the highest quality water.
  • Features the industry's thickest feed spacer (34 mil) to lessen the impact of fouling.
  • May be cleaned over the widest pH range (pH 1-13) for the most effective cleaning.

Elements with a hard shell exterior are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.
