BMSW8040-440 Equivalent LGSW400/440SR
BMSW-8040-440 model membrane element is a high-flux membrane developed and produced by Besta Membrane. This membrane element has an effective membrane area of 440 square inches, providing higher water flux and greater treatment capacity compared to the common 400 square inch membrane elements. It is an equivalent replacement for the LGSW400/440SR
SW series of fouling resistant aromatic polyamide composite membrane element is developed by BF for complex water quality. SW 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.
SW series membrane elements are generally suitable for the treatment of seawater and brackish water with high concentration. It can be used for seawater desalination, desalination of brackish water with high concentration, boiler replenishment water in power plants, wastewater reuse, concentration and recovery of high value-added substances such as food and pharmaceuticals, etc.
