RO Membrane Dupont FilmTec Seamax-440i

FilmTec Seamaxx-440i is a seawater extra low energy reverse osmosis membrane element designed for exceptional energy savings, stable long-term performance, and reliable seawater desalination in municipal, industrial, and high-energy-cost applications. With its advanced iLEC interlocking end caps and robust polyamide thin-film composite construction, it delivers high permeate flow and superior salt rejection even in challenging conditions. 1. Key Features of FilmTec Seamaxx-440i: Very High Permeate Flow – Enables significant energy savings by reducing the required feed pressure. Low System Capital Cost – Maximizes production capacity for lower infrastructure expenses. Excellent Long-Term Durability – Ensures stable performance over years of continuous operation. iLEC Interlocking End Caps – Reduces the risk of O-ring leaks and lowers system operating costs. Optimized for ISD – Perfect for Internally Staged Designs when combined with other FilmTec seawater membranes. 2.
