The Hydranautics SW-C5LD is an 8″ x 40″ low-fouling seawater reverse osmosis membrane built for high-salinity feedwater. It combines Hydranautics’ Low Differential (LD) design with a 34 mil feed spacer to limit colloidal and biological fouling, so cleaning cycles stay further apart. With 99.8% nominal salt rejection and about 92% typical boron rejection, it suits seawater desalination plants, boiler make-up water and other high-TDS applications.
