FilmTec BW30-4040

The FilmTec 4-inch membrane, model BW30-4040, is one of the most advanced elements used in industrial reverse osmosis (RO) desalination systems, capable of producing up to 9,000 liters per day (LPD) of high-quality treated water. Featuring a robust construction and optimized design, this membrane achieves over 99.5% rejection of dissolved salts, scale-forming compounds, and microbiological contaminants. Additionally, the incorporation of a feed spacer layer helps mitigate fouling and scaling on the membrane surface.

The BW30-4040 membrane is specifically designed for installation in pressure vessels (membrane housings) used in medium-scale industrial and semi-industrial systems. With compatibility for continuous chemical cleaning (CIP) and proper pre-treatment integration, it ensures reliable long-term performance and consistent production of purified water.
