Membrane
FILMTEC™ BW30-4040
DOW FILMTEC BW30-4040 brackish water reverse osmosis membrane elements offer consistent, exceptional system performance in light industrial applications. With the thickest feed spacer (34 mil) available in the industry today to lessen the impact of fouling, they may be cleaned over a wide 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.
