LG BW 400 AFR

Summary

Product identification

LG BW 400 AFR are brackish water reverse osmosis (RO) membranes. They incorporate innovative Thin Film Nanocomposite (TFN) technology, providing superior performance with intrinsic anti-fouling properties. These membranes offer enhanced fouling resistance and high rejection, suitable for brackish water and water reuse applications with challenging feed water.
