BMBW-2540 Equivalent LG BW 2540 R

BW series of sea water aromatic polyamide RO element developed by BM for brackish water desalination. It is an economical alternative to the LG BW 2540 R, offering the same water flux and treatment capacity.This series of elements have the characteristics of low operating pressure, low equipment investment, good desalination performance and stability. Among them, the BM-BW-4040 have the highest desalination rate of 99.8%, which ensure that drinking water can be produced from brackish water  through one pass RO system.

BW series membrane elements are generally suitable for the treatment of   brackish water with high concentration. It can be used for brackish water 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.
