BMBW-8040-400 Equivalent LG BWRO-8040
BMBW8040-400 is an economical alternative to the LG BW400 RO-8040.It has the advantages of high salt rejection, high water productivity, and high durability.
BW series of sea water aromatic polyamide RO element developed by BM for brackish water desalination. This series of elements have the characteristics of low operating pressure, low equipment investment, good desalination performance and stability. Among them, the BMBW-8040 have the highest desalination rate of 99.8%, which ensure that drinking water can be produced from brackish water through one pass RO system.It is an economical alternative to the Toray TML20D,LGBW400R,Nitto PROC10 etc.
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.
