LG Chem Brackish (BW) & Seawater (SW) RO Membranes
Lowering the Cost of Desalination
LG Chem Water Solutions has set a new standard for membrane productivity within the reverse osmosis desalination industry. Utilizing patent-pending thin-film nanocomposite membranes, LG Chem’s spiral-wound NanoH2O membrane elements deliver the highest flux and energy efficiency when compared to the current installed base. Extensive research and development in innovative technologies allow LG to manufacture membrane materials that demonstrate increased permeability and/or increased salt rejection, fundamentally changing the economics of desalination.
Our LG Chem Brackish and Seawater reverse osmosis membranes feature nanomaterials incorporated into the thin-film polyamide composite layer that improve membrane energy efficiency and productivity. The innovative patented technology significantly increases membrane permeability, increases flow, and reduces energy consumption, while matching best-in-class salt rejection.
LG Chem water anti-fouling membranes also feature proprietary chemistry to inhibit adsorption of biological and organic materials.

Dow UF Membranes
OW Integraflux Ultrafiltration (UF) Hollow Fiber Membranes
Ultrafiltration (UF) technology uses a membrane barrier to exclude particles as small as 0.01 microns, including bacteria, viruses, pathogens, suspended solids, and colloids. Advantages of UF compared to clarifiers and media filters, are its high tolerance to feed water quality upsets, absolute barrier and improved water quality. Our DOW IntegraFlux™ Ultrafiltration Modules and DOW IntegraPac™ Ultrafiltration Skids utilize the latest PVDF hollow fiber membranes in an outside-in flow configuration with a 0.03 micron nominal pore diameter making them an excellent choice to protect downstream processes such as RO.
