Proton Exchange Membrane for Water Treatment

Product Overview

The proton exchange membrane for water treatment is a high-performance composite membrane, featuring a high-strength PTFE (polytetrafluoroethylene) mesh support layer combined with perfluorosulfonic acid resin of optimized molecular weight and ion exchange capacity. It offers excellent chemical resistance and long service life, enabling efficient ion conduction in harsh environments such as high-salinity wastewater treatment and electrodialysis, providing reliable performance for industrial water purification and treatment processes.

Working Principle

The membrane achieves high-efficiency proton or ion conduction through ion channels formed by perfluorosulfonic acid resin, while maintaining electronic insulation and mechanical strength. It exhibits low swelling and stable dimensions under high-salinity, high-temperature, and high-humidity conditions, ensuring efficient and continuous ion transport during electrodialysis and wastewater treatment, thereby improving overall process efficiency.

Key Features

• Excellent Chemical Resistance and Durability:High-strength support layer and perfluorosulfonic acid resin ensure long-term stability in corrosive media.
• High Ionic Conductivity:Conductivity >0.100 S/cm, enabling rapid and efficient ion transport.
• Low Swelling Rate:Maintains dimensional stability under high-temperature and high-humidity conditions, ensuring uninterrupted operation.
• Robust Mechanical Structure:High tensile strength and elongation at break guarantee membrane durability and long service life.

Applications

• High-Salinity Wastewater Treatment:Efficiently removes ions from corrosive, high-salinity industrial wastewater.
• Electrodialysis Systems:Enhances ion separation and conduction efficiency, reducing operational costs and improving water treatment performance.
