Summary
Product Identification
LG SW 400 GR G2 is a Seawater Reverse Osmosis (RO) Membrane. These "next generation LG SW G2 membranes" utilize enhanced Thin Film Nanocomposite (TFN) technology to offer high salt rejection and low energy requirements, suitable for high salinity seawater applications.
Overview
LG SW G2 membranes achieve high salt rejection, with improvements in product quality compared to conventional technologies, and can significantly reduce desalination costs. LG SW GR (Great Rejection) membranes combine high rejection and low energy demands.
Key Benefits
- Improved permeate quality without increasing operating pressure
- Reduced energy cost without sacrificing permeate quality
- Reduced capital and operation costs for multi-pass SWRO systems
