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

• DOW FILMTEC LE-4040 delivers high performance at low pressure resulting in less energy usage and lower costs.
• Features the thickest feed spacer (34 mil) available in the industry today to lessen the impact of fouling.
• 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.
