LG Membranes

Industrial LG membranes are primarily sold under the LG Water Solutions brand, which is part of LG Chem’s water treatment business.

Their membrane technologies are widely used in industrial water treatment, desalination, ultrapure water production, and wastewater reuse.

LG membranes Water Solutions evolved from the NanoH₂O business and focuses on advanced membrane-based water treatment technologies. The brand serves municipal and industrial customers globally.

Main Industrial Membrane Product Lines

1. NanoH₂O™️ Reverse Osmosis (RO) Membranes

This is LG’s flagship industrial membrane brand.

Key characteristics:

* Thin-Film Nanocomposite (TFN) membrane technology
* High salt rejection performance
* Higher water permeability (flow)
* Lower energy consumption compared with conventional RO designs
* Anti-fouling and durability improvements for long operating life

Applications (LG membranes):

• Industrial process water

• Seawater desalination

• Brackish water treatment

• Ultrapure water systems

• Wastewater reuse

Typical categories:

• SWRO – Seawater Reverse Osmosis membranes

• BWRO– Brackish Water Reverse Osmosis membranes

• Commercial and industrial RO elements.

Example model:

1. BW 2540 R — designed for brackish water and light industrial/commercial use, emphasizing high salt rejection and long-term reliability.
2. QuantumFlux™️ UF / MBR Membranes

A newer membrane family for:

• Ultrafiltration (UF)

• Membrane Bioreactors (MBR)

Technology highlights:

• PVDF hollow-fiber construction

• Chemical and mechanical durability

• Municipal and industrial wastewater treatment

Why LG membranes are used in industry

Industrial users often choose LG membranes for:

• Reduced operating energy

• Stable permeate quality

• High rejection efficiency

• Long cleaning intervals

• Support for large-scale desalination and reuse projects
