BMBW8040-440 Equivalent To FilmTec BW30-440
BMBW8040-440 membrane element is a high-flux membrane developed and produced by Besta Membrane. This membrane element has an effective membrane area of 440 square inches, providing higher water flux and greater treatment capacity compared to the common 400 square inch membrane elements. It is an equivalent replacement for the Dow FilmTec BW30-440.
The BMBW8040-440 membrane element is a high-performance reverse osmosis membrane designed for various water qualities, including drinking water and industrial water. It is an economical alternative to the Dow FilmTec BW30-440,Toary TM720D-440 , offering the same water flux and treatment capacity.With an effective membrane area of 440 square inches, it provides higher water flux and greater treatment capacity compared to the standard 400 square inch membrane elements. Its excellent salt rejection performance effectively removes dissolved salts, heavy metals, microorganisms, and organic substances from the water, ensuring that the produced water meets industry standards. The BMBW8040-440 membrane element is suitable for a wide range of water treatment applications, such as municipal water treatment and industrial wastewater reuse, offering a long service life and low energy consumption. It is an ideal choice for improving water treatment efficiency and reducing operational costs.
