Reverse Osmosis Membrane 40-40
For 4'' x 40'' Demineralization Filters

Low Pressure Membrane 4’’ x 40’’

The high-quality 4’’ x 40’’ low-pressure membrane is an advanced solution for water treatment using reverse osmosis technology, designed to ensure high performance even with reduced operating pressures. Made of thin-film composite polyamide, it offers excellent separation capacity with an average salt rejection rate of 99.2%, ensuring high-quality treated water. Thanks to low-pressure operation, this membrane optimizes energy consumption and improves system efficiency without requiring structural modifications. With standard dimensions of 4 x 40 inches, an operating pressure of 6.9 bar, and a permeate flow rate of 6.8 lpm, it is ideal for applications with mains water and permeate concentrations up to approximately 500 mg/l. A reliable choice for professional water purification and treatment systems.

Functional Specifications

Reverse Osmosis Membrane for Tap Water Treatment

The Spectrum Premier PRO-4040 109574 low-pressure membrane is a reverse osmosis membrane designed for tap water treatment, offering high performance with lower pressure requirements compared to traditional membranes. The technology used achieves high quality of treated water thanks to an average rejection rate of 99.2%, effectively reducing the presence of dissolved salts and impurities. Made of thin-film composite polyamide (TFC), this 4-inch diameter and 40-inch long membrane is developed to ensure durability, reliability, and operational continuity in professional water treatment systems.

Optimized Low-Pressure Performance for Reverse Osmosis

The SPECTRUM PRO range has been designed to offer optimal permeate flows even at low operating pressures, starting from approximately 5.5 bar. The PRO-4040 membrane reaches its ideal balance at 6.9 bar, ensuring efficient and stable operation. The ability to operate at low pressure increases the overall efficiency of the system, limiting energy consumption while maintaining high filtration performance. The permeate flow rate reaches 6.8 L/min, making this membrane suitable for numerous professional applications.

The Fileder 109574 membrane is particularly suitable for systems using mains water with a permeate concentration generally equal to or less than 500 mg/l. It is an ideal solution for water purification systems for industrial, commercial, and professional activities requiring reliable and constant treatment.
