Toray TM820V-400 8040 is a high-performance seawater reverse osmosis (SWRO) membrane designed for efficient seawater desalination and industrial water treatment applications.
The Toray TM820V-400 8040 is an 8-inch × 40-inch seawater reverse osmosis (SWRO) membrane designed for efficient seawater desalination and high-salinity water treatment. Its spiral-wound thin-film composite membrane construction is designed to provide high salt rejection and reliable permeate production in demanding seawater RO applications. The standard 8040 configuration makes the membrane suitable for large-scale commercial and industrial desalination systems. The TM820V-400 is designed to remove dissolved salts, minerals, and other contaminants from seawater, producing high-quality permeate for drinking water, industrial process water, and other applications. The membrane is suitable for seawater desalination plants, municipal drinking-water production, industrial water treatment, marine applications, and water-reuse systems. Proper pretreatment is essential to control suspended solids, fouling, scaling, and other feed-water conditions that can affect membrane performance and service life.
