FR4040 Fouling Resistant RO Membrane CANATURE BW-4040FR

CANATURE BW-4040FR is a fouling-resistant reverse osmosis (RO) membrane designed for efficient removal of dissolved salts and other impurities from water. The membrane provides high salt rejection efficiency and helps reduce the risk of fouling and contaminant accumulation on the membrane surface.

The membrane is suitable for commercial and industrial reverse osmosis systems, particularly those treating brackish or pretreated water containing elevated levels of organic matter, colloids and other potential foulants.
