FILMTEC brackish water reverse osmosis membrane elements provide consistent, outstanding system performance in light industrial applications.FILMTEC BW30-2540 elements are designed for systems smaller than 1 gpm (0.2 m3/h) offering a hard shell exterior for extra strength.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.
