The LP22-8040 Reverse Osmosis Membrane is designed for high-capacity industrial and commercial reverse osmosis systems that require dependable performance under standard operating pressures. Manufactured using advanced thin film composite (TFC) membrane technology, the LP22-8040 delivers excellent rejection of dissolved salts, total dissolved solids (TDS), and other common water contaminants.
Built in the industry-standard 8" × 40" (8040) configuration, this membrane is widely compatible with industrial RO skids and large commercial water treatment systems. Its low-pressure design provides an optimal balance between energy efficiency and high permeate output, making it ideal for applications where ultra-low-pressure membranes are not required but consistent performance is critical.
The LP22-8040 is commonly used in industrial process water systems, manufacturing facilities, food and beverage processing, equipment feed water, and large commercial RO installations. High salt rejection ensures stable permeate quality, while robust membrane construction supports long service life when paired with proper pretreatment such as multimedia filtration, carbon filtration, and anti-scalant dosing.
For operators seeking reliable, cost-effective, and high-flow reverse osmosis performance, the LP22-8040 offers a proven solution for large-scale water purification.
