We are an Authorized Distributor for LG Water Solutions Membranes
LG Water Solutions Reverse Osmosis Membrane Collection
This comprehensive collection features professional-grade reverse osmosis (RO) and nanofiltration membrane elements from LG Water Solutions, engineered for high-performance water purification across commercial, industrial, municipal, and marine applications. As an authorized distributor, this lineup provides facility operators and water treatment professionals with direct access to advanced thin-film nanocomposite (TFC) membrane technology, delivering superior salt rejection, optimized flow rates, and exceptional energy efficiency.
The collection encompasses a diverse range of specialized product lines tailored to specific operating environments. This includes extra low energy (UES and ES) brackish water elements designed to minimize utility overhead, high-rejection (R) brackish and seawater (SW) desalination modules for extreme TDS removal, anti-fouling (AFR) elements engineered for challenging feedwaters, and specialized car wash (CW) spot-free rinse membranes. Available in industry-standard element dimensions—including 2.5-inch, 4.0-inch, and 8.0-inch diameters across multiple length configurations—these genuine LG elements ensure seamless integration into existing pressure vessel housings while maximizing operational reliability.
