Why LG NanoH2O TFN Membranes

  • Thin-Film Nanocomposite (TFN) technology — proprietary nano-particles embedded in the polyamide active layer deliver higher flux and improved salt rejection vs conventional TFC membranes.
  • Lower energy consumption — higher permeate flow at the same feed pressure means fewer elements and reduced CapEx/OpEx for the same plant output.
  • Improved fouling resistance — smoother, more hydrophilic surface chemistry reduces biofouling and scaling, extending cleaning intervals.
  • Proven at scale — installed in municipal and industrial plants worldwide, from small commercial systems to >500,000 m³/d desalination plants.

Compatibility & Replacement

LG-SW-440-SR-G2 is a standard 8" × 40" spiral-wound RO element and fits all industry-standard 8×40 pressure vessels (Codeline, Bekaert, Protec, ROPV, etc.). It is a like-for-like swap for Filmtec/DuPont, Hydranautics/Nitto, and Toray 8" × 40" seawater elements of comparable flow and rejection class.

B2B / OEM pricing available — volume discounts on full pressure vessel sets and container loads.
