4040FR RO Membrane Element is specially designed for water treatment against biological and organic fouling, which can improve the hydrophilicity, electric charge and roughness of its surface, being comparably lower than other RO membranes currently available, decreases the amount of colloidal substances from depositing on the membrane surface.

FR series of fouling resistant membranes normally suitable for treatment of complex water source with TDS less than 10000 ppm. It is mainly used for purification of surface water, mining waste water, municipal reclaimed water, industrial waste water, RO brackish water, etc.
