BMSW4021 Equivalent LG BW 4021 UES

SW series of sea water aromatic polyamide RO element developed by Beata Membrane for seawater desalination.It is an economical alternative to LG BW 4021 UES. This series of elements have the characteristics of low operating pressure, low equipment investment, good desalination performance and stability. Among them, the BM-SW-4040 have the highest desalination rate of 99.8%, which ensure that drinking water can be produced from seawater through one pass RO system.

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.
