CSM RE4040-BE RO Membrane

CSM RE4040-BE Brackish Water RO Membrane High-Performance 4" × 40" Reverse Osmosis Membrane The CSM RE4040-BE is a high rejection brackish water reverse osmosis membrane designed for commercial and industrial water purification systems. Manufactured by Toray Advanced Materials Korea under the CSM membrane brand, this 4040 RO membrane delivers reliable salt removal, high-quality permeate water and efficient performance in a wide range of water treatment applications. Specifications Parameter RE4040-BE Permeate flow 2,400 GPD (9.1 m³/day) Nominal salt rejection 99.7% Minimum salt rejection 99.4% Membrane area 85 ft² (7.9 m²) Test pressure 225 psi (15.5 bar) Test salinity 2,000 ppm NaCl Maximum feed water TDS 10,000 ppm NaCl Maximum temperature 45°C Certification NSF/ANSI/CAN 61 Permeate flow and rejection ratings are based on manufacturer test conditions. Actual performance varies with feed-water quality, operating pressure, temperature and recovery rate. Pre-treatment must be used to protect the membrane (softener, antiscalant dosing pump, sand filter, carbon filter, 5 mic cartridge fitler ...etc). About CSM CSM is a leading membrane brand manufactured by Toray Advanced Materials Korea, with decades of experience in membrane technology since 1994. CSM specialises in high-performance Reverse Osmosis (RO), Nanofiltration (NF) and Ultrafiltration (UF) membranes for residential, commercial and industrial water treatment applications. Known for their quality, reliability and advanced technology, CSM membranes are widely used in water purification, seawater desalination, ultrapure water production and wastewater recycling worldwide.
