The LG Chem SW-400-R is a high-rejection, 8-inch seawater reverse osmosis (SWRO) membrane designed for desalination applications. Engineered to withstand the harsh conditions of seawater, it delivers a permeate flow of 6,000 GPD with an exceptional salt rejection of 99.85%. Its robust construction and boron removal capabilities make it the ideal choice for converting seawater into high-purity potable or process water for coastal facilities, islands, and ships.
Key Features:
Model: LG-SW-400-R (8040)
Flow Rate: 6,000 Gallons Per Day (GPD)
Salt Rejection: 99.85%
Boron Rejection: > 93%
Max Operating Pressure: 1,200 psi
Built for Seawater Desalination
Technical Specifications & Performance:
Model: LG-SW-400-R
Standard Size: 8" diameter x 40" length (8040) - Industry-standard for easy replacement in SWRO pressure vessels.
Average Permeate Flow: 6,000 Gallons Per Day (GPD) / 22.7 m³/day under standard seawater test conditions (32,000 ppm NaCl, 800 psi, 77°F, 10% recovery, pH 8).
Minimum Salt Rejection: 99.85% - providing supreme removal of salts and total dissolved solids (TDS) from high-salinity feed water.
Boron Rejection: > 93% - a critical performance metric for producing water that meets strict drinking water standards.
Maximum Operating Pressure: 1,200 psi (83 bar) - constructed to handle the very high pressures required for seawater desalination.
Maximum Feed Flow Rate: 75 GPM (17 m³/hr).
