LG BW 440 R Brackish Water RO Membrane

LG BW 440 R brackish water RO membranes are lowers the cost of desalination by improving energy efficiency and productivity. These Thin-Film Nano-composite (TFN) membranes feature benign nanomaterials incorporated into the thin-film polyamide layer of a composite membrane. This innovative technology significantly increases membrane permeability while offering superior salt rejection. LG BW Membranes are suitable for pharmaceutical, oil & gas, food & beverages, municipal and industrial wastewater treatment plants in Dubai, UAE.

  • Matches industry-standard flux and rejection
  • Easy to retrofit existing systems
  • Well suited for low quality feed water or varying operating conditions
