150 GPD Watermaker Membrane 800 PSI 2.5 x 14 inch 99.5% Rejection

High-Performance 2.5" x 14" Watermaker RO Membrane

This industrial-grade, 2.5-inch by 14-inch spiral-wound reverse osmosis (RO) membrane is engineered specifically for high-efficiency freshwater production in compact marine watermakers and small-scale desalination systems. Proudly manufactured in the United States, it utilizes advanced thin-film composite (TFC) technology to effectively remove salts, minerals, and contaminants from high-salinity feed water. This premium watermaker membrane provides the consistent permeate output and rigorous salt rejection necessary to maintain a highly reliable supply of potable drinking water in demanding maritime and remote-access environments.

To ensure optimal system performance and maximize membrane longevity, this element requires a strict minimum feed flow rate of 0.75 GPM during operation. Maintaining this flow is critical for preventing concentration polarization and ensuring proper surface flushing; failure to provide this minimum flow may result in premature fouling and degraded performance, which are not covered under manufacturer warranties. When operated within the recommended parameters, this highly durable membrane delivers a nominal permeate flow rate of 150 gallons per day (GPD) at an applied pressure of 800 PSI, providing an efficient and robust solution for critical watermaker processing.
