LG RO Membrane

LG’s NanoH₂O™ membranes utilize patented Thin-Film Nanocomposite (TFN) technology—embedding benign nanoparticles into the top polyamide layer. This boosts water flux while maintaining industry-leading salt rejection, outperforming conventional TFC membranes

Features of LG RO Membranes

1. Thin-Film Nanocomposite (TFN) Technology

• Patented membrane structure with embedded nanoparticles in the active layer.

• Results in higher water flux and greater salt rejection than conventional thin-film composite (TFC) membranes.

• Reduces energy consumption and increases membrane life.

2. High Salt Rejection

• Salt rejection rates up to 99.89% for seawater membranes.

• Ideal for producing high-purity permeate in desalination and brackish water applications.

3. High Permeate Flow

• TFN design enhances water permeability, delivering greater flow at lower pressure.

• Reduces operating costs and system footprint in large-scale installations.

4. Excellent Fouling Resistance

• Smooth surface and optimized feed spacers (28–36 mil) reduce the likelihood of fouling by particulates, biofilm, and scaling.

• Extends cleaning intervals and membrane life.

5. Energy Efficiency

• Lower operating pressures due to higher permeability help save energy (especially in energy-saving models like LG ES series).

6. Durability & Cleaning Tolerance

• Wide pH range tolerance: pH 2–11 (operation), pH 1–13 (cleaning).

• Maximum operating pressure up to 1,200 psi (for seawater models).

7. NSF/ANSI-61 Certification

• Certified for drinking water applications, ensuring safety and regulatory compliance.

8. Wide Product Range

LG offers specialized membranes for:

• Brackish water (LG BW series) – high rejection, high flow, energy-saving options.

• Seawater (LG SW series) – high rejection and boron removal for desalination.

• Compact & commercial systems (LG 4040 sizes) – for small-scale plants or specialized uses (e.g. car wash).
