LG BW 4040 AFR

Anti-Fouling Brackish Water Reverse Osmosis (BWRO) Element

LG Chem’s anti-fouling (AF) brackish water NanoH2O™ RO membranes feature proprietary chemistry that reduces performance deterioration due to organic and biological fouling. Even with higher-fouling feed water, LG Chem’s unique AF formulation maintains membrane stability and performance without compromising the highly permeable nature of the membrane’s surface.
  • High rejection membrane that delivers superior water quality
  • Excellent fouling resistance
  • Well suited for low quality feed water or varying operating conditions
