LG CW 4040 SF RO membranes qualify for the car wash industry and other various commercial applications. LG CW 4040 SF RO membranes, incorporated with innovative Thin Film Nanocomposite (TFN) technology, offer high productivity at ultra-low feed pressure and good salt rejection. The membranes are available in industry standard 4”x40” configuration and can easily fit into existing or new industry RO systems.
