Reverse osmosis membrane

High-Performance Membrane for Water Purification

Product Overview

Reverse Osmosis (RO) Membranes are the core components of reverse osmosis water treatment systems, designed to effectively remove dissolved salts, heavy metals, bacteria, viruses, colloids, and organic matter from water.
Using advanced thin-film composite (TFC) membrane technology, RO membranes deliver high salt rejection, stable performance, and long service life.

They are widely used in industrial pure water production, seawater desalination, brackish water treatment, wastewater reuse, and ultrapure water systems.

Working Principle

Reverse osmosis membranes operate based on pressure-driven membrane separation:

  • Pressure is applied to feed water to overcome osmotic pressure

  • Water molecules pass through the semi-permeable membrane

  • Dissolved salts and impurities are rejected and discharged as concentrate

RO membranes typically remove up to 99.7% of dissolved salts, ensuring high-quality permeate water.
