Spiral-Wound Element w/ Polyamide Thin-Film Composite Membrane - 34 Mil Feed Spacer - 1 to 13 pH Cleaning - 40-Inch x 3.9-Inch

FilmTec™ BW30 PRO-4040 is a reverse osmosis (RO) membrane element designed for industrial and commercial water treatment applications. It features a polyamide thin-film composite membrane with high salt rejection (99.7%) and reliable permeate flow rates, making it suitable for challenging feed water conditions.

Key characteristics include:

• Fiberglass outer wrap for durability in multi-element pressure vessels.

• Enhanced fouling resistance due to an advanced membrane chemistry and thicker feed spacer.

• Quick stabilization when transitioning from dry to wet operation.

• Wide pH tolerance (1–13) for effective cleaning and maintenance.

• Compatibility with nominal 4-inch inner diameter (I.D.) pressure vessels.

This membrane is commonly used in light industrial processes and drinking water systems requiring high-quality permeate. Its robust construction and consistent performance make it a reliable choice for harsh operating environments.

(Note: Specifications are based on standard test conditions—2,000 ppm NaCl, 225 psi, 77°F, pH 8, and 15% recovery.)
