In applications such as high-salinity water, seawater desalination, and industrial water treatment, long-term stability and high desalination efficiency are critical for RO membranes. Through continuous innovation and precise engineering, HJC has developed high-performance RO membranes that reliably operate in demanding water environments, providing dependable solutions for customers worldwide.
1 Four-Layer Membrane Structure
Under high-pressure, high-TDS conditions, traditional three-layer membranes are prone to scratches or fouling, leading to reduced desalination performance. HJC adds a protective layer to enhance durability and maintain stable performance under challenging water conditions.
Technical Features:
l Protection Layer: Shields the desalination layer from particle damage, ensuring long-term stability
l Desalination Layer: Ultra-thin for high-efficiency desalination
l Polysulfone Layer: Provides mechanical strength and pressure resistance
l Non-woven Fabric Support Layer: Enhances structural stability and extends membrane lifespan
2 Heat-Sealing Technology
Beyond membrane structure, the sealing method determines long-term reliability. Conventional room-temperature sealants may tear or leak under high pressure. HJC’s heat-sealing process uses heat-melt bonding to achieve strong adhesion, ensuring membrane integrity and stable performance under demanding conditions.
Benefits:
l Reliable sealing under high pressure
l Minimizes risk of leakage
l Improves overall system stability
3 Air Flotation Low-Temperature Drying
High-temperature drying can damage organic RO membranes, affecting performance and lifespan. HJC employs air flotation low-temperature drying, which reduces drying temperatures and precisely controls the environment to fully dry membranes without overheating or causing damage.
Key Advantages:
l Preserves membrane material integrity
l Maintains long-term desalination performance
l Suitable for a wide range of complex water conditions
4 Application-Based Customization
Different water sources require tailored membrane solutions. HJC combines scientific selection of auxiliary materials with extensive experimental data to customize membrane element combinations for seawater, high-salinity water, and industrial wastewater, ensuring optimal water quality and system performance.
Application Benefits:
l Precisely matches water quality requirements
l Improves output water quality
l Maximizes membrane performance and lifespan
