ΜΕΜΒΡΑΝΗ ΑΝΤΙΣΤΡΟΦΗΣ ΩΣΜΩΣΗΣ ΘΑΛΑΣΣΙΝΟΥ ΝΕΡΟΥ 4″ SW-4040MR – MWG

The MWG SW-4040MR is a 4″ × 40″ spiral-wound reverse osmosis membrane designed for seawater desalination. It provides a nominal permeate flow of 1,800 GPD, equivalent to 6.8 m³/day, with a nominal salt rejection of 99.7% and an effective membrane area of 7.9 m².

The stated performance is based on test conditions of 800 psi, 25°C, 32,000 ppm sodium chloride concentration and 8% recovery. Actual permeate flow and quality depend on feed-water salinity, temperature, operating pressure, recovery rate and the overall design of the desalination system.
