FilmTec™ BW30-4040 Elements are an industry standard for reliable operation and production of high quality water in light industrial applications. This element features the thickest feed spacer (34 mil) available in the industry today to lessen the impact of fouling as well as a fiberglassed shell, which is recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops. The element may be cleaned over a wide pH range (pH 1 – 13) for the most effective cleaning.
