BMBW-8040- FR Equivalent CPA5 Max

FR series of fouling resistant aromatic polyamide composite membrane element is developed by BM for complex water quality. FR series element with special membrane preparation process, it improved the hydrophilicity, charge characteristic and roughness, can effectively reduce the breeding of biofouling and adsorption of pollutants in the membrane surface. The element is applied a special 34 mil spacer design, which effectively reduced fouling and pressure drop, with more durable on cleaning can extent the service life.

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.
