FilmTec NF90-4040 Membranes are designed for selective removal of divalent and larger organic contaminants while maintaining high water permeability. Engineered to deliver consistent performance, this membrane is ideal for water treatment applications requiring efficient separation and long-term durability. Its robust construction ensures reliable operation in diverse industrial and commercial environments. Features: High rejection of total organic carbon (TOC), trihalomethane (THM) precursors, and per- and polyfluoroalkyl substances (PFAS). High rejection of components such as salts, hardness, nitrates and iron. Excellent fouling protection. High productivity and low energy consumption with effective cleanability due to its wide cleaning (pH 1 - 13) tolerance. Includes iLEC™ interlocking end caps, reducing system operating costs and the risk of O-ring leaks that can cause poor water quality.
