LG SW 440 GR G2 SWRO Membranes

Original price was: 690 $.Current price is: 675 $.

Among the LG SW G2 series, the LG SW 440 GR G2 (Great Rejection) SWRO membranes are designed to cater to high-salinity seawater applications. These membranes combine high rejection rates with low energy requirements, ultimately reducing the total cost of desalination.

The LG SW 440 GR G2 membranes are suitable for applications where high salt concentrations in seawater are a concern, making them ideal for use in coastal areas where seawater has a higher salt content. With their superior performance and low cost of operation, LG SW 440 GR G2 membranes are an excellent choice for seawater desalination projects.
